-Cc: mpagano@gentoo.org
-
-[ Upstream commit 2ab957492d13bb819400ac29ae55911d50a82a13 ]
-
-Initial discussion was:
-[FYI] xfrm: Don't lookup sk_policy for timewait sockets
-
-Forwarded frames should not have a socket attached. Especially
-tw sockets will lead to panics later-on in the stack.
-
-This was observed with TPROXY assigning a tw socket and broken
-policy routing (misconfigured). As a result frame enters
-forwarding path instead of input. We cannot solve this in
-TPROXY as it cannot know that policy routing is broken.
-
-v2:
-Remove useless comment

-Cc: mpagano@gentoo.org
-
-[ Upstream commit d83769a580f1132ac26439f50068a29b02be535e ]
-
-Using sk_stream_alloc_skb() in tcp_send_fin() is dangerous in
-case a huge process is killed by OOM, and tcp_mem[2] is hit.
-
-To be able to free memory we need to make progress, so this
-patch allows FIN packets to not care about tcp_mem[2], if
-skb allocation succeeded.
-
-In a follow-up patch, we might abort tcp_send_fin() infinite loop
-in case TIF_MEMDIE is set on this thread, as memory allocator
-did its best getting extra memory already.

-Cc: mpagano@gentoo.org
-
-[ Upstream commit 845704a535e9b3c76448f52af1b70e4422ea03fd ]
-
-Presence of an unbound loop in tcp_send_fin() had always been hard
-to explain when analyzing crash dumps involving gigantic dying processes
-with millions of sockets.
-
-Lets try a different strategy :
-
-In case of memory pressure, try to add the FIN flag to last packet
-in write queue, even if packet was already sent. TCP stack will
-be able to deliver this FIN after a timeout event. Note that this
-FIN being delivered by a retransmit, it also carries a Push flag
-given our current implementation.
-
-By checking sk_under_memory_pressure(), we anticipate that cooking
-many FIN packets might deplete tcp memory.
-
-In the case we could not allocate a packet, even with __GFP_WAIT
-allocation, then not sending a FIN seems quite reasonable if it allows
-to get rid of this socket, free memory, and not block the process from
-eventually doing other useful work.

-Cc: mpagano@gentoo.org
-
-[ Upstream commit 79930f5892e134c6da1254389577fffb8bd72c66 ]
-
-build_skb() should look at the page pfmemalloc status.
-If set, this means page allocator allocated this page in the
-expectation it would help to free other pages. Networking
-stack can do that only if skb->pfmemalloc is also set.
-
-Also, we must refrain using high order pages from the pfmemalloc
-reserve, so __page_frag_refill() must also use __GFP_NOMEMALLOC for
-them. Under memory pressure, using order-0 pages is probably the best
-strategy.

-Subject: [PATCH 007/219] net: fix crash in build_skb()
-Cc: mpagano@gentoo.org
-
-[ Upstream commit 2ea2f62c8bda242433809c7f4e9eae1c52c40bbe ]
-
-When I added pfmemalloc support in build_skb(), I forgot netlink
-was using build_skb() with a vmalloc() area.
-
-In this patch I introduce __build_skb() for netlink use,
-and build_skb() is a wrapper handling both skb->head_frag and
-skb->pfmemalloc
-
-This means netlink no longer has to hack skb->head_frag

-Cc: mpagano@gentoo.org
-
-[ Upstream commit 0e03fd3e335d272bee88fe733d5fd13f5c5b7140 ]
-
-Commit 43d3ddf87a57 ("net: pxa168_eth: add device tree support") starts
-to use managed resources by adding devm_clk_get() and
-devm_ioremap_resource(), but it leaves explicit iounmap() and clock_put()
-in pxa168_eth_remove() and in failure handling code of pxa168_eth_probe().
-As a result double free can happen.
-
-The patch removes explicit resource deallocation. Also it converts
-clk_disable() to clk_disable_unprepare() to make it symmetrical with
-clk_prepare_enable().
-
-Found by Linux Driver Verification project (linuxtesting.org).

-Cc: mpagano@gentoo.org
-
-[ Upstream commit a31196b07f8034eba6a3487a1ad1bb5ec5cd58a5 ]
-
-Commit 567e4b79731c ("net: rfs: add hash collision detection") had one
-mistake :
-
-RPS_NO_CPU is no longer the marker for invalid cpu in set_rps_cpu()
-and get_rps_cpu(), as @next_cpu was the result of an AND with
-rps_cpu_mask
-
-This bug showed up on a host with 72 cpus :
-next_cpu was 0x7f, and the code was trying to access percpu data of an
-non existent cpu.
-
-In a follow up patch, we might get rid of compares against nr_cpu_ids,
-if we init the tables with 0. This is silly to test for a very unlikely
-condition that exists only shortly after table initialization, as
-we got rid of rps_reset_sock_flow() and similar functions that were
-writing this RPS_NO_CPU magic value at flow dismantle : When table is
-old enough, it never contains this value anymore.

-Subject: [PATCH 010/219] net/mlx4_en: Prevent setting invalid RSS hash
- function
-Cc: mpagano@gentoo.org
-
-[ Upstream commit b37069090b7c5615610a8aa6b36533d67b364d38 ]
-
-mlx4_en_check_rxfh_func() was checking for hardware support before
-setting a known RSS hash function, but didn't do any check before
-setting unknown RSS hash function. Need to make it fail on such values.
-In this occasion, moved the actual setting of the new value from the
-check function into mlx4_en_set_rxfh().
-
-Fixes: 947cbb0 ("net/mlx4_en: Support for configurable RSS hash function")

-Cc: mpagano@gentoo.org
-
-commit 74672d069b298b03e9f657fd70915e055739882e upstream.
-
-Simon reported the md io stats accounting issue:
-"
-I'm seeing "iostat -x -k 1" print this after a RAID1 rebuild on 4.0-rc5.
-It's not abnormal other than it's 3-disk, with one being SSD (sdc) and
-the other two being write-mostly:
-
-Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util
-sda 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00

-"
-The cause is commit "18c0b223cf9901727ef3b02da6711ac930b4e5d4" uses the
-generic_start_io_acct to account the disk stats rather than the open code,
-but it also introduced the increase to .in_flight[rw] which is needless to
-md. So we re-use the open code here to fix it.

-Subject: [PATCH 012/219] x86/asm/decoder: Fix and enforce max instruction size
- in the insn decoder
-Cc: mpagano@gentoo.org
-
-commit 91e5ed49fca09c2b83b262b9757d1376ee2b46c3 upstream.
-
-x86 instructions cannot exceed 15 bytes, and the instruction
-decoder should enforce that. Prior to 6ba48ff46f76, the
-instruction length limit was implicitly set to 16, which was an
-approximation of 15, but there is currently no limit at all.
-
-Fix MAX_INSN_SIZE (it should be 15, not 16), and fix the decoder
-to reject instructions that exceed MAX_INSN_SIZE.
-
-Other than potentially confusing some of the decoder sanity
-checks, I'm not aware of any actual problems that omitting this
-check would cause, nor am I aware of any practical problems
-caused by the MAX_INSN_SIZE error.

-
-If we were migrated right after __getcpu, but before reading the
-migration_count, we wouldn't notice that we read TSC of a different
-VCPU, nor that KVM's bug made pvti invalid, as only migration_count
-on source VCPU is increased.
-
-Change vdso instead of updating migration_count on destination.

-Subject: [PATCH 015/219] sched/idle/x86: Restore mwait_idle() to fix boot
- hangs, to improve power savings and to improve performance
-Cc: mpagano@gentoo.org
-
-commit b253149b843f89cd300cbdbea27ce1f847506f99 upstream.
-
-In Linux-3.9 we removed the mwait_idle() loop:
-
- 69fb3676df33 ("x86 idle: remove mwait_idle() and "idle=mwait" cmdline param")
-
-The reasoning was that modern machines should be sufficiently
-happy during the boot process using the default_idle() HALT
-loop, until cpuidle loads and either acpi_idle or intel_idle
-invoke the newer MWAIT-with-hints idle loop.
-
-But two machines reported problems:
-
- 1. Certain Core2-era machines support MWAIT-C1 and HALT only.
- MWAIT-C1 is preferred for optimal power and performance.
- But if they support just C1, cpuidle never loads and
- so they use the boot-time default idle loop forever.
-
- 2. Some laptops will boot-hang if HALT is used,
- but will boot successfully if MWAIT is used.
- This appears to be a hidden assumption in BIOS SMI,
- that is presumably valid on the proprietary OS
- where the BIOS was validated.
-
- https://bugzilla.kernel.org/show_bug.cgi?id=60770
-
-So here we effectively revert the patch above, restoring
-the mwait_idle() loop. However, we don't bother restoring
-the idle=mwait cmdline parameter, since it appears to add
-no value.
-
-Maintainer notes:
-
- For 3.9, simply revert 69fb3676df
- for 3.10, patch -F3 applies, fuzz needed due to __cpuinit use in
- context For 3.11, 3.12, 3.13, this patch applies cleanly

-Subject: [PATCH 016/219] sched/idle/x86: Optimize unnecessary mwait_idle()
- resched IPIs
-Cc: mpagano@gentoo.org
-
-commit f8e617f4582995f7c25ef25b4167213120ad122b upstream.
-
-To fully take advantage of MWAIT, apparently the CLFLUSH instruction needs
-another quirk on certain CPUs: proper barriers around it on certain machines.
-
-On a Q6600 SMP system, pipe-test scheduling performance, cross core,
-improves significantly:
-
- 3.8.13 487.2 KHz 1.000
- 3.13.0-master 415.5 KHz .852
- 3.13.0-master+ 415.2 KHz .852 + restore mwait_idle
- 3.13.0-master++ 488.5 KHz 1.002 + restore mwait_idle + IPI fix
-
-Since X86_BUG_CLFLUSH_MONITOR is already a quirk, don't create a separate
-quirk for the extra smp_mb()s.

-Subject: [PATCH 018/219] x86: fix special __probe_kernel_write() tail zeroing
- case
-Cc: mpagano@gentoo.org
-
-commit d869844bd081081bf537e806a44811884230643e upstream.
-
-Commit cae2a173fe94 ("x86: clean up/fix 'copy_in_user()' tail zeroing")
-fixed the failure case tail zeroing of one special case of the x86-64
-generic user-copy routine, namely when used for the user-to-user case
-("copy_in_user()").
-
-But in the process it broke an even more unusual case: using the user
-copy routine for kernel-to-kernel copying.
-
-Now, normally kernel-kernel copies are obviously done using memcpy(),
-but we have a couple of special cases when we use the user-copy
-functions. One is when we pass a kernel buffer to a regular user-buffer
-routine, using set_fs(KERNEL_DS). That's a "normal" case, and continued
-to work fine, because it never takes any faults (with the possible
-exception of a silent and successful vmalloc fault).
-
-But Jan Beulich pointed out another, very unusual, special case: when we
-use the user-copy routines not because it's a path that expects a user
-pointer, but for a couple of ftrace/kgdb cases that want to do a kernel
-copy, but do so using "unsafe" buffers, and use the user-copy routine to
-gracefully handle faults. IOW, for probe_kernel_write().
-
-And that broke for the case of a faulting kernel destination, because we
-saw the kernel destination and wanted to try to clear the tail of the
-buffer. Which doesn't work, since that's what faults.
-
-This only triggers for things like kgdb and ftrace users (eg trying
-setting a breakpoint on read-only memory), but it's definitely a bug.
-The fix is to not compare against the kernel address start (TASK_SIZE),
-but instead use the same limits "access_ok()" uses.

-Cc: mpagano@gentoo.org
-
-commit 9e9c3fe40bcd28e3f98f0ad8408435f4503f2781 upstream.
-
-kvm_init_msr_list is currently called before hardware_setup. As a result,
-vmx_mpx_supported always returns false when kvm_init_msr_list checks whether to
-save MSR_IA32_BNDCFGS.
-
-Move kvm_init_msr_list after vmx_hardware_setup is called to fix this issue.

-Subject: [PATCH 020/219] Btrfs: fix log tree corruption when fs mounted with
- -o discard
-Cc: mpagano@gentoo.org
-
-commit dcc82f4783ad91d4ab654f89f37ae9291cdc846a upstream.
-
-While committing a transaction we free the log roots before we write the
-new super block. Freeing the log roots implies marking the disk location
-of every node/leaf (metadata extent) as pinned before the new super block
-is written. This is to prevent the disk location of log metadata extents
-from being reused before the new super block is written, otherwise we
-would have a corrupted log tree if before the new super block is written
-a crash/reboot happens and the location of any log tree metadata extent
-ended up being reused and rewritten.
-
-Even though we pinned the log tree's metadata extents, we were issuing a
-discard against them if the fs was mounted with the -o discard option,
-resulting in corruption of the log tree if a crash/reboot happened before
-writing the new super block - the next time the fs was mounted, during
-the log replay process we would find nodes/leafs of the log btree with
-a content full of zeroes, causing the process to fail and require the
-use of the tool btrfs-zero-log to wipeout the log tree (and all data
-previously fsynced becoming lost forever).
-
-Fix this by not doing a discard when pinning an extent. The discard will
-be done later when it's safe (after the new super block is committed) at
-extent-tree.c:btrfs_finish_extent_commit().
-
-Fixes: e688b7252f78 (Btrfs: fix extent pinning bugs in the tree log)

-Cc: mpagano@gentoo.org
-
-commit 3c3b04d10ff1811a27f86684ccd2f5ba6983211d upstream.
-
-Due to insufficient check in btrfs_is_valid_xattr, this unexpectedly
-works:
-
- $ touch file
- $ setfattr -n user. -v 1 file
- $ getfattr -d file
-user.="1"
-
-ie. the missing attribute name after the namespace.

-
-So just bail out of the clone ioctl if the length of the region to clone
-is zero, without locking any extent range, in order to prevent this issue
-(same behaviour as a pwrite with a 0 length for example).
-
-This is trivial to reproduce. For example, the steps for the test I just
-made for fstests:
-
- mkfs.btrfs -f SCRATCH_DEV
- mount SCRATCH_DEV $SCRATCH_MNT
-
- touch $SCRATCH_MNT/foo
- touch $SCRATCH_MNT/bar
-
- $CLONER_PROG -s 0 -d 4096 -l 0 $SCRATCH_MNT/foo $SCRATCH_MNT/bar
- umount $SCRATCH_MNT
-
-A test case for fstests follows soon.

-Subject: [PATCH 023/219] Btrfs: fix inode eviction infinite loop after
- extent_same ioctl
-Cc: mpagano@gentoo.org
-
-commit 113e8283869b9855c8b999796aadd506bbac155f upstream.
-
-If we pass a length of 0 to the extent_same ioctl, we end up locking an
-extent range with a start offset greater then its end offset (if the
-destination file's offset is greater than zero). This results in a warning
-from extent_io.c:insert_state through the following call chain:
-
- btrfs_extent_same()
- btrfs_double_lock()
- lock_extent_range()
- lock_extent(inode->io_tree, offset, offset + len - 1)
- lock_extent_bits()
- __set_extent_bit()
- insert_state()
- --> WARN_ON(end < start)
-
-This leads to an infinite loop when evicting the inode. This is the same
-problem that my previous patch titled
-"Btrfs: fix inode eviction infinite loop after cloning into it" addressed
-but for the extent_same ioctl instead of the clone ioctl.

-Subject: [PATCH 024/219] mm/hugetlb: use pmd_page() in follow_huge_pmd()
-Cc: mpagano@gentoo.org
-
-commit 97534127012f0e396eddea4691f4c9b170aed74b upstream.
-
-Commit 61f77eda9bbf ("mm/hugetlb: reduce arch dependent code around
-follow_huge_*") broke follow_huge_pmd() on s390, where pmd and pte
-layout differ and using pte_page() on a huge pmd will return wrong
-results. Using pmd_page() instead fixes this.
-
-All architectures that were touched by that commit have pmd_page()
-defined, so this should not break anything on other architectures.

-Cc: mpagano@gentoo.org
-
-commit 50c6a665b383cb5839e45d04e36faeeefaffa052 upstream.
-
-Commit dc6c9a35b66b5 ("mm: account pmd page tables to the process")
-added a counter that is incremented whenever a PMD is allocated and
-decremented whenever a PMD is freed. For hugepages on PPC, common code
-is used to allocated PMDs, but arch-specific code is used to free PMDs.
-
-This results in kernel output such as "BUG: non-zero nr_pmds on freeing
-mm: 1" when using hugepages.
-
-Update the PPC hugepage PMD freeing code to decrement the count, just
-as the above commit did for free_pmd_range().

-Subject: [PATCH 026/219] usb: gadget: printer: enqueue printer's response for
- setup request
-Cc: mpagano@gentoo.org
-
-commit eb132ccbdec5df46e29c9814adf76075ce83576b upstream.
-
-Function-specific setup requests should be handled in such a way, that
-apart from filling in the data buffer, the requests are also actually
-enqueued: if function-specific setup is called from composte_setup(),
-the "usb_ep_queue()" block of code in composite_setup() is skipped.
-
-The printer function lacks this part and it results in e.g. get device id
-requests failing: the host expects some response, the device prepares it
-but does not equeue it for sending to the host, so the host finally asserts
-timeout.
-
-This patch adds enqueueing the prepared responses.

-Cc: mpagano@gentoo.org
-
-commit 261520dcfcba93ca5dfe671b88ffab038cd940c8 upstream.
-
-If the I/O interrupt could not be written to the guest provided
-area (e.g. access exception), a program exception was injected into the
-guest but "inti" wasn't freed, therefore resulting in a memory leak.
-
-In addition, the I/O interrupt wasn't reinjected. Therefore the dequeued
-interrupt is lost.
-
-This patch fixes the problem while cleaning up the function and making the
-cc and rc logic easier to handle.

-Cc: mpagano@gentoo.org
-
-commit 15462e37ca848abac7477dece65f8af25febd744 upstream.
-
-The reinjection of an I/O interrupt can fail if the list is at the limit
-and between the dequeue and the reinjection, another I/O interrupt is
-injected (e.g. if user space floods kvm with I/O interrupts).
-
-This patch avoids this memory leak and returns -EFAULT in this special
-case. This error is not recoverable, so let's fail hard. This can later
-be avoided by not dequeuing the interrupt but working directly on the
-locked list.

-Subject: [PATCH 030/219] KVM: s390: fix get_all_floating_irqs
-Cc: mpagano@gentoo.org
-
-commit 94aa033efcac47b09db22cb561e135baf37b7887 upstream.
-
-This fixes a bug introduced with commit c05c4186bbe4 ("KVM: s390:
-add floating irq controller").
-
-get_all_floating_irqs() does copy_to_user() while holding
-a spin lock. Let's fix this by filling a temporary buffer
-first and copy it to userspace after giving up the lock.

-Subject: [PATCH 031/219] s390/hibernate: fix save and restore of kernel text
- section
-Cc: mpagano@gentoo.org
-
-commit d74419495633493c9cd3f2bbeb7f3529d0edded6 upstream.
-
-Sebastian reported a crash caused by a jump label mismatch after resume.
-This happens because we do not save the kernel text section during suspend
-and therefore also do not restore it during resume, but use the kernel image
-that restores the old system.
-
-This means that after a suspend/resume cycle we lost all modifications done
-to the kernel text section.
-The reason for this is the pfn_is_nosave() function, which incorrectly
-returns that read-only pages don't need to be saved. This is incorrect since
-we mark the kernel text section read-only.
-We still need to make sure to not save and restore pages contained within
-NSS and DCSS segment.
-To fix this add an extra case for the kernel text section and only save
-those pages if they are not contained within an NSS segment.
-
-Fixes the following crash (and the above bugs as well):
-
-Jump label code mismatch at netif_receive_skb_internal+0x28/0xd0
-Found: c0 04 00 00 00 00
-Expected: c0 f4 00 00 00 11

-Subject: [PATCH 033/219] KVM: arm/arm64: check IRQ number on userland
- injection
-Cc: mpagano@gentoo.org
-
-commit fd1d0ddf2ae92fb3df42ed476939861806c5d785 upstream.
-
-When userland injects a SPI via the KVM_IRQ_LINE ioctl we currently
-only check it against a fixed limit, which historically is set
-to 127. With the new dynamic IRQ allocation the effective limit may
-actually be smaller (64).
-So when now a malicious or buggy userland injects a SPI in that
-range, we spill over on our VGIC bitmaps and bytemaps memory.
-I could trigger a host kernel NULL pointer dereference with current
-mainline by injecting some bogus IRQ number from a hacked kvmtool:
------------------
-....
-DEBUG: kvm_vgic_inject_irq(kvm, cpu=0, irq=114, level=1)
-DEBUG: vgic_update_irq_pending(kvm, cpu=0, irq=114, level=1)
-DEBUG: IRQ #114 still in the game, writing to bytemap now...
-Unable to handle kernel NULL pointer dereference at virtual address 00000000
-pgd = ffffffc07652e000
-[00000000] *pgd=00000000f658b003, *pud=00000000f658b003, *pmd=0000000000000000
-Internal error: Oops: 96000006 [#1] PREEMPT SMP
-Modules linked in:
-CPU: 1 PID: 1053 Comm: lkvm-msi-irqinj Not tainted 4.0.0-rc7+ #3027
-Hardware name: FVP Base (DT)
-task: ffffffc0774e9680 ti: ffffffc0765a8000 task.ti: ffffffc0765a8000
-PC is at kvm_vgic_inject_irq+0x234/0x310
-LR is at kvm_vgic_inject_irq+0x30c/0x310
-pc : [<ffffffc0000ae0a8>] lr : [<ffffffc0000ae180>] pstate: 80000145
-.....
-
-So this patch fixes this by checking the SPI number against the
-actual limit. Also we remove the former legacy hard limit of
-127 in the ioctl code.

- mode.
-Cc: mpagano@gentoo.org
-
-commit 085e68eeafbf76e21848ad5bafaecec88a11dd64 upstream.
-
-The host's decision to enable machine check exceptions should remain
-in force during non-root mode. KVM was writing 0 to cr4 on VCPU reset
-and passed a slightly-modified 0 to the vmcs.guest_cr4 value.
-
-Tested: Built.
-On earlier version, tested by injecting machine check
-while a guest is spinning.
-
-Before the change, if guest CR4.MCE==0, then the machine check is
-escalated to Catastrophic Error (CATERR) and the machine dies.
-If guest CR4.MCE==1, then the machine check causes VMEXIT and is
-handled normally by host Linux. After the change, injecting a machine
-check causes normal Linux machine check handling.

-Subject: [PATCH 035/219] MIPS: KVM: Handle MSA Disabled exceptions from guest
-Cc: mpagano@gentoo.org
-
-commit 98119ad53376885819d93dfb8737b6a9a61ca0ba upstream.
-
-Guest user mode can generate a guest MSA Disabled exception on an MSA
-capable core by simply trying to execute an MSA instruction. Since this
-exception is unknown to KVM it will be passed on to the guest kernel.
-However guest Linux kernels prior to v3.15 do not set up an exception
-handler for the MSA Disabled exception as they don't support any MSA
-capable cores. This results in a guest OS panic.
-
-Since an older processor ID may be being emulated, and MSA support is
-not advertised to the guest, the correct behaviour is to generate a
-Reserved Instruction exception in the guest kernel so it can send the
-guest process an illegal instruction signal (SIGILL), as would happen
-with a non-MSA-capable core.
-
-Fix this as minimally as reasonably possible by preventing
-kvm_mips_check_privilege() from relaying MSA Disabled exceptions from
-guest user mode to the guest kernel, and handling the MSA Disabled
-exception by emulating a Reserved Instruction exception in the guest,
-via a new handle_msa_disabled() KVM callback.

-Cc: mpagano@gentoo.org
-
-commit acaf6a97d623af123314c2f8ce4cf7254f6b2fc1 upstream.
-
-The lose_fpu() function only disables the FPU in CP0_Status.CU1 if the
-FPU is in use and MSA isn't enabled.
-
-This isn't necessarily a problem because KSTK_STATUS(current), the
-version of CP0_Status stored on the kernel stack on entry from user
-mode, does always get updated and gets restored when returning to user
-mode, but I don't think it was intended, and it is inconsistent with the
-case of only the FPU being in use. Sometimes leaving the FPU enabled may
-also mask kernel bugs where FPU operations are executed when the FPU
-might not be enabled.
-
-So lets disable the FPU in the MSA case too.

-Subject: [PATCH 037/219] MIPS: Malta: Detect and fix bad memsize values
-Cc: mpagano@gentoo.org
-
-commit f7f8aea4b97c4d48e42f02cb37026bee445f239f upstream.
-
-memsize denotes the amount of RAM we can access from kseg{0,1} and
-that should be up to 256M. In case the bootloader reports a value
-higher than that (perhaps reporting all the available RAM) it's best
-if we fix it ourselves and just warn the user about that. This is
-usually a problem with the bootloader and/or its environment.
-
-[ralf@linux-mips.org: Remove useless parens as suggested bei Sergei.
-Reformat long pr_warn statement to fit into 80 column limit.]

-Subject: [PATCH 039/219] MIPS: unaligned: Prevent EVA instructions on kernel
- unaligned accesses
-Cc: mpagano@gentoo.org
-
-commit eeb538950367e3966cbf0237ab1a1dc30e059818 upstream.
-
-Commit c1771216ab48 ("MIPS: kernel: unaligned: Handle unaligned
-accesses for EVA") allowed unaligned accesses to be emulated for
-EVA. However, when emulating regular load/store unaligned accesses,
-we need to use the appropriate "address space" instructions for that.
-Previously, an unaligned load/store instruction in kernel space would
-have used the corresponding EVA instructions to emulate it which led to
-segmentation faults because of the address translation that happens
-with EVA instructions. This is now fixed by using the EVA instruction
-only when emulating EVA unaligned accesses.

-Subject: [PATCH 040/219] MIPS: unaligned: Surround load/store macros in do {}
- while statements
-Cc: mpagano@gentoo.org
-
-commit 3563c32d6532ece53c9dd8905a8e41983ef9952f upstream.
-
-It's best to surround such complex macros with do {} while statements
-so they can appear as independent logical blocks when used within other
-control blocks.

-Subject: [PATCH 041/219] MIPS: unaligned: Fix regular load/store instruction
- emulation for EVA
-Cc: mpagano@gentoo.org
-
-commit 6eae35485b26f9e51ab896eb8a936bed9908fdf6 upstream.
-
-When emulating a regular lh/lw/lhu/sh/sw we need to use the appropriate
-instruction if we are in EVA mode. This is necessary for userspace
-applications which trigger alignment exceptions. In such case, the
-userspace load/store instruction needs to be emulated with the correct
-eva/non-eva instruction by the kernel emulator.

-Cc: mpagano@gentoo.org
-
-commit 0add9c2f1cff9f3f1f2eb7e9babefa872a9d14b9 upstream.
-
-HPET irq is routed to i8259 and then to MIPS CPU irq (cascade). After
-commit a3e6c1eff5 (MIPS: IRQ: Fix disable_irq on CPU IRQs), if without
-IRQF_NO_SUSPEND in cascade_irqaction, HPET interrupts will lost during
-suspend. The result is machine cannot be waken up.

-Cc: mpagano@gentoo.org
-
-commit 2c20d92dad5db6440cfa88d811b69fd605240ce4 upstream.
-
-the lcd type as defined in the Kconfig is not matching in the code.
-as a result the rs, rw and en pins were getting interchanged.
-Kconfig defines the value of PANEL_LCD to be 1 if we select custom
-configuration but in the code LCD_TYPE_CUSTOM is defined as 5.
-
-my hardware is LCD_TYPE_CUSTOM, but the pins were assigned to it
-as pins of LCD_TYPE_OLD, and it was not working.
-Now values are corrected with referenece to the values defined in
-Kconfig and it is working.
-checked on JHD204A lcd with LCD_TYPE_CUSTOM configuration.

-Subject: [PATCH 045/219] staging: android: sync: Fix memory corruption in
- sync_timeline_signal().
-Cc: mpagano@gentoo.org
-
-commit 8e43c9c75faf2902955bd2ecd7a50a8cc41cb00a upstream.
-
-The android_fence_release() function checks for active sync points
-by calling list_empty() on the list head embedded on the sync
-point. However, it is only valid to use list_empty() on nodes that
-have been initialized with INIT_LIST_HEAD() or list_del_init().
-
-Because the list entry has likely been removed from the active list
-by sync_timeline_signal(), there is a good chance that this
-WARN_ON_ONCE() will be hit due to dangling pointers pointing at
-freed memory (even though the sync drivers did nothing wrong)
-and memory corruption will ensue as the list entry is removed for
-a second time, corrupting the active list.
-
-This problem can be reproduced quite easily with CONFIG_DEBUG_LIST=y
-and fences with more than one sync point.

-Subject: [PATCH 047/219] md/raid0: fix bug with chunksize not a power of 2.
-Cc: mpagano@gentoo.org
-
-commit 47d68979cc968535cb87f3e5f2e6a3533ea48fbd upstream.
-
-Since commit 20d0189b1012a37d2533a87fb451f7852f2418d1
-in v3.14-rc1 RAID0 has performed incorrect calculations
-when the chunksize is not a power of 2.
-
-This happens because "sector_div()" modifies its first argument, but
-this wasn't taken into account in the patch.
-
-So restore that first arg before re-using the variable.

- the caches
-Cc: mpagano@gentoo.org
-
-commit 8a7d95f95c95f396decbd4cda6d4903fc4664946 upstream.
-
-On architectures that depend on DT for obtaining cache hierarcy, we need
-to validate the device node for all the cache indices, failing to do so
-might result in wrong information being exposed to the userspace.
-
-This is quite possible on initial/incomplete versions of the device
-trees. In such cases, it's better to bail out if all the required device
-nodes are not present.
-
-This patch adds checks for the validation of device node for all the
-caches and doesn't initialise the cacheinfo if there's any error.

- reset control
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-Cc: mpagano@gentoo.org
-
-commit 9e71c589e44ddf2b86f361c81e360c6b0d0354b1 upstream.
-
-The reset control for the sunxi mmc controller is optional. Some
-newer platforms (sun6i, sun8i, sun9i) have it, while older ones
-(sun4i, sun5i, sun7i) don't.
-
-Use the properly stubbed _optional version so the driver does not
-fail to compile when RESET_CONTROLLER=n.
-
-This patch also adds a check for deferred probing on the reset
-control.

-Cc: mpagano@gentoo.org
-
-commit f511ab09dfb0fe7b2335eccac51ff9f001a32e4a upstream.
-
-They are used to decide if the controller can do DMA on a buffer
-of a specific length and thus are needed before any transfer is attempted.
-
-This fixes a memory leak where the SPI core uses the drivers can_dma()
-callback to determine if a buffer needs to be mapped. As the watermark
-levels aren't correct at that point the driver falsely claims to be able to
-DMA the buffer when it fact it isn't.
-After the transfer has been done the core uses the same callback to
-determine if it needs to unmap the buffers. As the driver now correctly
-claims to not being able to DMA the buffer the core doesn't attempt to
-unmap the buffer which leaves the SGT leaking.

-Subject: [PATCH 054/219] spi: spidev: fix possible arithmetic overflow for
- multi-transfer message
-Cc: mpagano@gentoo.org
-
-commit f20fbaad7620af2df36a1f9d1c9ecf48ead5b747 upstream.
-
-`spidev_message()` sums the lengths of the individual SPI transfers to
-determine the overall SPI message length. It restricts the total
-length, returning an error if too long, but it does not check for
-arithmetic overflow. For example, if the SPI message consisted of two
-transfers and the first has a length of 10 and the second has a length
-of (__u32)(-1), the total length would be seen as 9, even though the
-second transfer is actually very long. If the second transfer specifies
-a null `rx_buf` and a non-null `tx_buf`, the `copy_from_user()` could
-overrun the spidev's pre-allocated tx buffer before it reaches an
-invalid user memory address. Fix it by checking that neither the total
-nor the individual transfer lengths exceed the maximum allowed value.
-
-Thanks to Dan Carpenter for reporting the potential integer overflow.

-

-
-The return value of power_supply_register() call was not checked and
-even on error probe() function returned 0. If registering failed then
-during unbind the driver tried to unregister power supply which was not
-actually registered.
-
-This could lead to memory corruption because power_supply_unregister()

-
-Fix this by checking return status of power_supply_register() call. In

-Subject: [PATCH 057/219] ring-buffer: Replace this_cpu_*() with __this_cpu_*()
-Cc: mpagano@gentoo.org
-
-commit 80a9b64e2c156b6523e7a01f2ba6e5d86e722814 upstream.
-
-It has come to my attention that this_cpu_read/write are horrible on
-architectures other than x86. Worse yet, they actually disable
-preemption or interrupts! This caused some unexpected tracing results
-on ARM.
-
- 101.356868: preempt_count_add <-ring_buffer_lock_reserve
- 101.356870: preempt_count_sub <-ring_buffer_lock_reserve
-
-The ring_buffer_lock_reserve has recursion protection that requires
-accessing a per cpu variable. But since preempt_disable() is traced, it
-too got traced while accessing the variable that is suppose to prevent
-recursion like this.
-
-The generic version of this_cpu_read() and write() are:
-
- #define this_cpu_generic_read(pcp) \
- ({ typeof(pcp) ret__; \
- preempt_disable(); \
- ret__ = *this_cpu_ptr(&(pcp)); \
- preempt_enable(); \
- ret__; \
- })
-
- #define this_cpu_generic_to_op(pcp, val, op) \
- do { \
- unsigned long flags; \
- raw_local_irq_save(flags); \
- *__this_cpu_ptr(&(pcp)) op val; \
- raw_local_irq_restore(flags); \
- } while (0)
-
-Which is unacceptable for locations that know they are within preempt
-disabled or interrupt disabled locations.
-
-Paul McKenney stated that __this_cpu_() versions produce much better code on
-other architectures than this_cpu_() does, if we know that the call is done in
-a preempt disabled location.
-
-I also changed the recursive_unlock() to use two local variables instead
-of accessing the per_cpu variable twice.

-Cc: mpagano@gentoo.org
-
-commit 68c3ed6fa7e0d69529ced772d650ab128916a81d upstream.
-
-The return value of power_supply_register() call was not checked and
-even on error probe() function returned 0. If registering failed then
-during unbind the driver tried to unregister power supply which was not
-actually registered.
-
-This could lead to memory corruption because power_supply_unregister()
-unconditionally cleans up given power supply.

- in probe
-Cc: mpagano@gentoo.org
-
-commit a2c1d531854c4319610f1d83351213b47a633969 upstream.
-
-The return values of create_singlethread_workqueue() and
-power_supply_register() calls were not checked and even on error probe()
-function returned 0.
-
-1. If allocation of workqueue failed (returning NULL) then further
- accesses could lead to NULL pointer dereference. The
- queue_delayed_work() expects workqueue to be non-NULL.
-
-2. If registration of power supply failed then during unbind the driver
- tried to unregister power supply which was not actually registered.
- This could lead to memory corruption because
- power_supply_unregister() unconditionally cleans up given power
- supply.

-Subject: [PATCH 064/219] NFS: fix BUG() crash in notify_change() with patch to
- chown_common()
-Cc: mpagano@gentoo.org
-
-commit c1b8940b42bb6487b10f2267a96b486276ce9ff7 upstream.
-
-We have observed a BUG() crash in fs/attr.c:notify_change(). The crash
-occurs during an rsync into a filesystem that is exported via NFS.
-
-1.) fs/attr.c:notify_change() modifies the caller's version of attr.
-2.) 6de0ec00ba8d ("VFS: make notify_change pass ATTR_KILL_S*ID to
- setattr operations") introduced a BUG() restriction such that "no
- function will ever call notify_change() with both ATTR_MODE and
- ATTR_KILL_S*ID set". Under some circumstances though, it will have
- assisted in setting the caller's version of attr to this very
- combination.
-3.) 27ac0ffeac80 ("locks: break delegations on any attribute
- modification") introduced code to handle breaking
- delegations. This can result in notify_change() being re-called. attr
- _must_ be explicitly reset to avoid triggering the BUG() established
- in #2.
-4.) The path that that triggers this is via fs/open.c:chmod_common().
- The combination of attr flags set here and in the first call to
- notify_change() along with a later failed break_deleg_wait()
- results in notify_change() being called again via retry_deleg
- without resetting attr.
-
-Solution is to move retry_deleg in chmod_common() a bit further up to
-ensure attr is completely reset.
-
-There are other places where this seemingly could occur, such as
-fs/utimes.c:utimes_common(), but the attr flags are not initially
-set in such a way to trigger this.
-
-Fixes: 27ac0ffeac80 ("locks: break delegations on any attribute modification")

-Subject: [PATCH 065/219] ARM: fix broken hibernation
-Cc: mpagano@gentoo.org
-
-commit 767bf7e7a1e82a81c59778348d156993d0a6175d upstream.
-
-Normally, when a CPU wants to clear a cache line to zero in the external
-L2 cache, it would generate bus cycles to write each word as it would do
-with any other data access.
-
-However, a Cortex A9 connected to a L2C-310 has a specific feature where
-the CPU can detect this operation, and signal that it wants to zero an
-entire cache line. This feature, known as Full Line of Zeros (FLZ),
-involves a non-standard AXI signalling mechanism which only the L2C-310
-can properly interpret.
-
-There are separate enable bits in both the L2C-310 and the Cortex A9 -
-the L2C-310 needs to be enabled and have the FLZ enable bit set in the
-auxiliary control register before the Cortex A9 has this feature
-enabled.
-
-Unfortunately, the suspend code was not respecting this - it's not
-obvious from the code:
-
-swsusp_arch_suspend()
- cpu_suspend() /* saves the Cortex A9 auxiliary control register */
- arch_save_image()
- soft_restart() /* turns off FLZ in Cortex A9, and disables L2C */
- cpu_resume() /* restores the Cortex A9 registers, inc auxcr */
-
-At this point, we end up with the L2C disabled, but the Cortex A9 with
-FLZ enabled - which means any memset() or zeroing of a full cache line
-will fail to take effect.
-
-A similar issue exists in the resume path, but it's slightly more
-complex:
-
-swsusp_arch_suspend()
- cpu_suspend() /* saves the Cortex A9 auxiliary control register */
- arch_save_image() /* image with A9 auxcr saved */
-...
-swsusp_arch_resume()
- call_with_stack()
- arch_restore_image() /* restores image with A9 auxcr saved above */
- soft_restart() /* turns off FLZ in Cortex A9, and disables L2C */
- cpu_resume() /* restores the Cortex A9 registers, inc auxcr */
-
-Again, here we end up with the L2C disabled, but Cortex A9 FLZ enabled.
-
-There's no need to turn off the L2C in either of these two paths; there
-are benefits from not doing so - for example, the page copies will be
-faster with the L2C enabled.
-
-Hence, fix this by providing a variant of soft_restart() which can be
-used without turning the L2 cache controller off, and use it in both
-of these paths to keep the L2C enabled across the respective resume
-transitions.
-
-Fixes: 8ef418c7178f ("ARM: l2c: trial at enabling some Cortex-A9 optimisations")

-Subject: [PATCH 066/219] ARM: 8320/1: fix integer overflow in ELF_ET_DYN_BASE
-Cc: mpagano@gentoo.org
-
-commit 8defb3367fcd19d1af64c07792aade0747b54e0f upstream.
-
-Usually ELF_ET_DYN_BASE is 2/3 of TASK_SIZE. With 3G/1G user/kernel
-split this is not so, because 2*TASK_SIZE overflows 32 bits,
-so the actual value of ELF_ET_DYN_BASE is:
- (2 * TASK_SIZE / 3) = 0x2a000000
-
-When ASLR is disabled PIE binaries will load at ELF_ET_DYN_BASE address.
-On 32bit platforms AddressSanitzer uses addresses [0x20000000 - 0x40000000]
-for shadow memory [1]. So ASan doesn't work for PIE binaries when ASLR disabled
-as it fails to map shadow memory.
-Also after Kees's 'split ET_DYN ASLR from mmap ASLR' patchset PIE binaries
-has a high chance of loading somewhere in between [0x2a000000 - 0x40000000]
-even if ASLR enabled. This makes ASan with PIE absolutely incompatible.
-
-Fix overflow by dividing TASK_SIZE prior to multiplying.
-After this patch ELF_ET_DYN_BASE equals to (for CONFIG_VMSPLIT_3G=y):
- (TASK_SIZE / 3 * 2) = 0x7f555554

-
-commit 548ae94c1cc7fc120848757249b9a542b1080ffb upstream.
-
-On Armada 38x SoCs, under heavy I/O load, the system hangs when CPU
-Idle is enabled. Waiting for a solution to this issue, this patch
-disables the CPU Idle support for this SoC.
-
-As CPU Hot plug support also uses some of the CPU Idle functions it is
-also affected by the same issue. This patch disables it also for the
-Armada 38x SoCs.

- on Cragganmore
-Cc: mpagano@gentoo.org
-
-commit 4e330ae4ab2915444f1e6dca1358a910aa259362 upstream.
-
-There are two PMICs on Cragganmore, currently one dynamically assign
-its IRQ base and the other uses a fixed base. It is possible for the
-statically assigned PMIC to fail if its IRQ is taken by the dynamically
-assigned one. Fix this by statically assigning both the IRQ bases.

-Cc: mpagano@gentoo.org

-commit 98b80987c940956da48f0c703f60340128bb8521 upstream.
-
-After 57a38effa598 (net: phy: micrel: disable broadcast for KSZ8081/KSZ8091)
-the macb1 interface refuses to work properly because it tries
-to cling to address 0 which isn't able to communicate in broadcast with
-the mac anymore. The micrel phy on the board is actually configured
-to show up at address 1.
-Adding the phy node and its real address fixes the issue.

-Cc: mpagano@gentoo.org
-
-commit e3c93e1a3f35be4cf1493d3ccfb0c6d9209e4922 upstream.
-
-As per Mentor Graphics' documentation, we should
-always handle TX endpoints before RX endpoints.
-
-This patch fixes that error while also updating
-some hard-to-read comments which were scattered
-around musb_interrupt().
-
-This patch should be backported as far back as
-possible since this error has been in the driver
-since it's conception.

-Subject: [PATCH 074/219] usb: define a generic USB_RESUME_TIMEOUT macro
-Cc: mpagano@gentoo.org
-
-commit 62f0342de1f012f3e90607d39e20fce811391169 upstream.
-
-Every USB Host controller should use this new
-macro to define for how long resume signalling
-should be driven on the bus.
-
-Currently, almost every single USB controller
-is using a 20ms timeout for resume signalling.
-
-That's problematic for two reasons:
-
-a) sometimes that 20ms timer expires a little
-before 20ms, which makes us fail certification
-
-b) some (many) devices actually need more than
-20ms resume signalling.
-
-Sure, in case of (b) we can state that the device
-is against the USB spec, but the fact is that
-we have no control over which device the certification
-lab will use. We also have no control over which host
-they will use. Most likely they'll be using a Windows
-PC which, again, we have no control over how that
-USB stack is written and how long resume signalling
-they are using.
-
-At the end of the day, we must make sure Linux passes
-electrical compliance when working as Host or as Device
-and currently we don't pass compliance as host because
-we're driving resume signallig for exactly 20ms and
-that confuses certification test setup resulting in
-Certification failure.

+/*
-+ * USB Resume Timer: Every Host controller driver should drive the resume
-+ * signalling on the bus for the amount of time defined by this macro.
-+ *
-+ * That way we will have a 'stable' behavior among all HCDs supported by Linux.
-+ *
-+ * Note that the USB Specification states we should drive resume for *at least*
-+ * 20 ms, but it doesn't give an upper bound. This creates two possible
-+ * situations which we want to avoid:
-+ *
-+ * (a) sometimes an msleep(20) might expire slightly before 20 ms, which causes
-+ * us to fail USB Electrical Tests, thus failing Certification
-+ *
-+ * (b) Some (many) devices actually need more than 20 ms of resume signalling,
-+ * and while we can argue that's against the USB Specification, we don't have
-+ * control over which devices a certification laboratory will be using for
-+ * certification. If CertLab uses a device which was tested against Windows and
-+ * that happens to have relaxed resume signalling rules, we might fall into
-+ * situations where we fail interoperability and electrical tests.
-+ *
-+ * In order to avoid both conditions, we're using a 40 ms resume timeout, which
-+ * should cope with both LPJ calibration errors and devices not following every
-+ * detail of the USB Specification.
++ * This type of clock has a glitch-free mux that switches between the output of
++ * the M/N counter and an always on clock source (XO). When clk_set_rate() is
++ * called we need to make sure that we don't switch to the M/N counter if it
++ * isn't clocking because the mux will get stuck and the clock will stop
++ * outputting a clock. This can happen if the framework isn't aware that this
++ * clock is on and so clk_set_rate() doesn't turn on the new parent. To fix
++ * this we switch the mux in the enable/disable ops and reprogram the M/N
++ * counter in the set_rate op. We also make sure to switch away from the M/N
++ * counter in set_rate if software thinks the clock is off.

-Cc: mpagano@gentoo.org
-
-commit 7a606ac29752a3e571b83f9b3fceb1eaa1d37781 upstream.
-
-While this driver was already using a 50ms resume
-timeout, let's make sure everybody uses the same
-macro so it's easy to fix later should anything
-go wrong.
-
-It also gives a more "stable" expectation to Linux
-users.

- parent clk
-Cc: mpagano@gentoo.org
-
-commit 4591243102faa8de92da320edea47219901461e9 upstream.
-
-The at91sam9n12 and at91sam9x5 usb clocks do not propagate rate
-modification requests to their parents.
-This causes a bug when the PLLB is left uninitialized by the bootloader
-(PLL multiplier set to 0, or in other words, PLL rate = 0 Hz).
-
-Implement the determinate_rate method and propagate the change rate
-request to the parent clk.

-Cc: mpagano@gentoo.org
-
-commit eef0342cf32689f77d78ee3302999e5caaa6a8f3 upstream.
-
-Adds Microsoft LifeCam Cinema USB ID to the snd_usb_get_sample_rate_quirk list as the Lifecam Cinema does not appear to support getting the sample rate.
-
-Fixes the issue where the LifeCam Cinema would wait for USB timeout and log the message "cannot get freq at ep 0x82" when accessed.
-
-Addresses bug report https://bugzilla.kernel.org/show_bug.cgi?id=95961.

-Cc: mpagano@gentoo.org
-
-commit 91bf0c2dcb935a87e5c0795f5047456b965fd143 upstream.
-
-The functions snd_emu10k1_proc_spdif_read and snd_emu1010_fpga_read
-acquire the emu_lock before accessing the FPGA. The function used
-to access the FPGA (snd_emu1010_fpga_read) also tries to take
-the emu_lock which causes a deadlock.
-Remove the outer locking in the proc-functions (guarding only the
-already safe fpga read) to prevent this deadlock.
-
-[removed superfluous flags variables too -- tiwai]

-Subject: [PATCH 093/219] ALSA: hda - fix "num_steps = 0" error on ALC256
-Cc: mpagano@gentoo.org
-
-commit 7d1b6e29327428993ba568bdd8c66734070f45e0 upstream.
-
-The ALC256 does not have a mixer nid at 0x0b, and there's no
-loopback path (the output pins are directly connected to the DACs).
-
-This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)"
-error (and as a result, problems with amixer/alsamixer).
-
-If there's pcbeep functionality, it certainly isn't controlled by setting an
-amp on 0x0b, so disable beep functionality (at least for now).

-Subject: [PATCH 096/219] Input: elantech - fix absolute mode setting on some
- ASUS laptops
-Cc: mpagano@gentoo.org
-
-commit bd884149aca61de269fd9bad83fe2a4232ffab21 upstream.
-
-On ASUS TP500LN and X750JN, the touchpad absolute mode is reset each
-time set_rate is done.
-
-In order to fix this, we will verify the firmware version, and if it
-matches the one in those laptops, the set_rate function is overloaded
-with a function elantech_set_rate_restore_reg_07 that performs the
-set_rate with the original function, followed by a restore of reg_07
-(the register that sets the absolute mode on elantech v4 hardware).
-
-Also the ASUS TP500LN and X750JN firmware version, capabilities, and
-button constellation is added to elantech.c

-Subject: [PATCH 097/219] Input: alps - fix touchpad buttons getting stuck when
- used with trackpoint
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-Cc: mpagano@gentoo.org
-
-commit 6bcca19f5dcedc3a006ca0bcc3699a437cadee74 upstream.
-
-When the left touchpad button gets pressed, and then the trackpoint is
-moved, and then the button is released, the following happens:
-
-1) touchpad packet is received, touchpad evdev node reports BTN_LEFT 1
-
-2) pointing stick packet is received, the hw will report a BTN_LEFT 1 in
- this packet because when the trackstick is active it communicates the
- combined touchpad + pointing stick buttons in the trackstick packet,
- since alps_report_bare_ps2_packet passes NULL (*) for the dev2 parameter
- to alps_report_buttons the combining is not detected and the
- pointing stick evdev node will also report BTN_LEFT 1
-
-3) on release of the button a pointing stick packet with BTN_LEFT 0 is
- received and the pointing stick evdev node will report BTN_LEFT 0
-
-Note how because of the passing as NULL for dev2 the touchpad evdev node
-will never send BTN_LEFT 0 in this scenario leading to a stuck mouse button.
-
-This is a regression in 4.0 introduced by commit 04aae283ba6a8
-("Input: ALPS - do not mix trackstick and external PS/2 mouse data")
-
-This commit fixes this by passing in the touchpad evdev as dev2 parameter
-when calling alps_report_buttons for the pointingstick on alps v2 devices,
-so that alps_report_buttons correctly detect that we're already reporting
-the button as pressed via the touchpad evdev node, and will also send the
-release event there.

-Cc: mpagano@gentoo.org
-
-commit a77c50b44cfb663ad03faba9800fec19bdf83577 upstream.
-
-Since commit 6e3f62f0793e ("mfd: core: Fix platform-device id
-generation") we honour PLATFORM_DEVID_AUTO and PLATFORM_DEVID_NONE when
-registering mfd-devices.
-
-Unfortunately, some mfd-drivers rely on the old behaviour of generating
-platform-device ids by adding the cell id also to the special value of
-PLATFORM_DEVID_NONE. The resulting platform ids are not only used to
-generate device-unique names, but are also used instead of the cell id
-to identify cells when probing subdevices.
-
-These drivers should be updated to use PLATFORM_DEVID_AUTO, which would
-also allow more than one device to be registered without resorting to
-hacks (see for example wm831x), but lets fix the regression first by
-partially reverting the above mentioned commit with respect to
-PLATFORM_DEVID_NONE.

-Subject: [PATCH 099/219] fs/binfmt_elf.c: fix bug in loading of PIE binaries
-Cc: mpagano@gentoo.org
-
-commit a87938b2e246b81b4fb713edb371a9fa3c5c3c86 upstream.
-
-With CONFIG_ARCH_BINFMT_ELF_RANDOMIZE_PIE enabled, and a normal top-down
-address allocation strategy, load_elf_binary() will attempt to map a PIE
-binary into an address range immediately below mm->mmap_base.
-
-Unfortunately, load_elf_ binary() does not take account of the need to
-allocate sufficient space for the entire binary which means that, while
-the first PT_LOAD segment is mapped below mm->mmap_base, the subsequent
-PT_LOAD segment(s) end up being mapped above mm->mmap_base into the are
-that is supposed to be the "gap" between the stack and the binary.
-
-Since the size of the "gap" on x86_64 is only guaranteed to be 128MB this
-means that binaries with large data segments > 128MB can end up mapping
-part of their data segment over their stack resulting in corruption of the
-stack (and the data segment once the binary starts to run).
-
-Any PIE binary with a data segment > 128MB is vulnerable to this although
-address randomization means that the actual gap between the stack and the
-end of the binary is normally greater than 128MB. The larger the data
-segment of the binary the higher the probability of failure.
-
-Fix this by calculating the total size of the binary in the same way as
-load_elf_interp().

-Subject: [PATCH 100/219] ptrace: fix race between ptrace_resume() and
- wait_task_stopped()
-Cc: mpagano@gentoo.org
-
-commit b72c186999e689cb0b055ab1c7b3cd8fffbeb5ed upstream.
-
-ptrace_resume() is called when the tracee is still __TASK_TRACED. We set
-tracee->exit_code and then wake_up_state() changes tracee->state. If the
-tracer's sub-thread does wait() in between, task_stopped_code(ptrace => T)
-wrongly looks like another report from tracee.
-
-This confuses debugger, and since wait_task_stopped() clears ->exit_code
-the tracee can miss a signal.
-
-Test-case:
-
- #include <stdio.h>
- #include <unistd.h>
- #include <sys/wait.h>
- #include <sys/ptrace.h>
- #include <pthread.h>
- #include <assert.h>
-
- int pid;
-
- void *waiter(void *arg)
- {
- int stat;
-
- for (;;) {
- assert(pid == wait(&stat));
- assert(WIFSTOPPED(stat));
- if (WSTOPSIG(stat) == SIGHUP)
- continue;
-
- assert(WSTOPSIG(stat) == SIGCONT);
- printf("ERR! extra/wrong report:%x\n", stat);
- }
- }
-
- int main(void)
- {
- pthread_t thread;
-
- pid = fork();
- if (!pid) {
- assert(ptrace(PTRACE_TRACEME, 0,0,0) == 0);
- for (;;)
- kill(getpid(), SIGHUP);
- }
-
- assert(pthread_create(&thread, NULL, waiter, NULL) == 0);
-
- for (;;)
- ptrace(PTRACE_CONT, pid, 0, SIGCONT);
-
- return 0;
- }
-
-Note for stable: the bug is very old, but without 9899d11f6544 "ptrace:
-ensure arch_ptrace/ptrace_request can never race with SIGKILL" the fix
-should use lock_task_sighand(child).

- Baytrail SOC
-Cc: mpagano@gentoo.org
-
-commit d7ef76717322c8e2df7d4360b33faa9466cb1a0d upstream.
-
-On some Silvermont-Core/Baytrail-SOC systems,
-C1E latency is higher than original specifications.
-Although C1E is still enumerated in CPUID.MWAIT.EDX,
-we delete the state from intel_idle to avoid latency impact.
-
-Under some conditions, the latency of the C6N-BYT and C6S-BYT states
-may exceed the specified values of 40 and 140 usec, respectively.
-Increase those values to 300 and 500 usec; to assure
-that the hardware does not violate constraints that may be set
-by the Linux PM_QOS sub-system.
-
-Also increase the C7-BYT target residency to 4.0 ms from 1.5 ms.

-One of them got out of sync after modification by 8a013a9c71b2 (net: macb:

-Subject: [PATCH 106/219] ext4: make fsync to sync parent dir in no-journal for
- real this time
-Cc: mpagano@gentoo.org
-
-commit e12fb97222fc41e8442896934f76d39ef99b590a upstream.
-
-Previously commit 14ece1028b3ed53ffec1b1213ffc6acaf79ad77c added a
-support for for syncing parent directory of newly created inodes to
-make sure that the inode is not lost after a power failure in
-no-journal mode.
-
-However this does not work in majority of cases, namely:
- - if the directory has inline data
- - if the directory is already indexed
- - if the directory already has at least one block and:
- - the new entry fits into it
- - or we've successfully converted it to indexed
-
-So in those cases we might lose the inode entirely even after fsync in
-the no-journal mode. This also includes ext2 default mode obviously.
-
-I've noticed this while running xfstest generic/321 and even though the
-test should fail (we need to run fsck after a crash in no-journal mode)
-I could not find a newly created entries even when if it was fsynced
-before.
-
-Fix this by adjusting the ext4_add_entry() successful exit paths to set
-the inode EXT4_STATE_NEWENTRY so that fsync has the chance to fsync the
-parent directory as well.

-Cc: mpagano@gentoo.org
-
-commit e819f152104c9f7c9fe50e1aecce6f5d4bf06d65 upstream.
-
-- Remove the unneeded declaration from pnode.h
-- Mark umount_tree static as it has no callers outside of namespace.c
-- Define an enumeration of umount_tree's flags.
-- Pass umount_tree's flags in by name
-
-This removes the magic numbers 0, 1 and 2 making the code a little
-clearer and makes it possible for there to be lazy unmounts that don't
-propagate. Which is what __detach_mounts actually wants for example.

-Cc: mpagano@gentoo.org
-
-commit 8318e667f176f7ea34451a1a530634e293f216ac upstream.
-
-Invoking mount propagation from __detach_mounts is inefficient and
-wrong.
-
-It is inefficient because __detach_mounts already walks the list of
-mounts that where something needs to be done, and mount propagation
-walks some subset of those mounts again.
-
-It is actively wrong because if the dentry that is passed to
-__detach_mounts is not part of the path to a mount that mount should
-not be affected.
-
-change_mnt_propagation(p,MS_PRIVATE) modifies the mount propagation
-tree of a master mount so it's slaves are connected to another master
-if possible. Which means even removing a mount from the middle of a
-mount tree with __detach_mounts will not deprive any mount propagated
-mount events.

-Cc: mpagano@gentoo.org
-
-commit c003b26ff98ca04a180ff34c38c007a3998d62f9 upstream.
-
-umount_tree builds a list of mounts that need to be unmounted.
-Utilize mnt_list for this purpose instead of mnt_hash. This begins to
-allow keeping a mount on the mnt_hash after it is unmounted, which is
-necessary for a properly functioning MNT_LOCKED implementation.
-
-The fact that mnt_list is an ordinary list makding available list_move
-is nice bonus.

-Cc: mpagano@gentoo.org
-
-commit 590ce4bcbfb4e0462a720a4ad901e84416080bba upstream.
-
-In some instances it is necessary to know if the the unmounting
-process has begun on a mount. Add MNT_UMOUNT to make that reliably
-testable.
-
-This fix gets used in fixing locked mounts in MNT_DETACH

-Cc: mpagano@gentoo.org
-
-commit 411a938b5abc9cb126c41cccf5975ae464fe0f3e upstream.
-
-- Modify __lookup_mnt_hash_last to ignore mounts that have MNT_UMOUNTED set.
-- Don't remove mounts from the mount hash table in propogate_umount
-- Don't remove mounts from the mount hash table in umount_tree before
- the entire list of mounts to be umounted is selected.
-- Remove mounts from the mount hash table as the last thing that
- happens in the case where a mount has a parent in umount_tree.
- Mounts without parents are not hashed (by definition).
-
-This paves the way for delaying removal from the mount hash table even
-farther and fixing the MNT_LOCKED vs MNT_DETACH issue.

-Cc: mpagano@gentoo.org
-
-commit 5d88457eb5b86b475422dc882f089203faaeedb5 upstream.
-
-A prerequisite of calling umount_tree is that the point where the tree
-is mounted at is valid to unmount.
-
-If we are propagating the effect of the unmount clear MNT_LOCKED in
-every instance where the same filesystem is mounted on the same
-mountpoint in the mount tree, as we know (by virtue of the fact
-that umount_tree was called) that it is safe to reveal what
-is at that mountpoint.

-
-If the first mount in shared subtree is locked don't unmount the
-shared subtree.
-
-This is ensured by walking through the mounts parents before children
-and marking a mount as unmountable if it is not locked or it is locked
-but it's parent is marked.
-
-This allows recursive mount detach to propagate through a set of
-mounts when unmounting them would not reveal what is under any locked
-mount.

-Create a function unhash_mnt that contains the common code between
-detach_mnt and umount_tree, and use unhash_mnt in place of the common
-code. This add a unncessary list_del_init(mnt->mnt_child) into
-umount_tree but given that mnt_child is already empty this extra
-line is a noop.

-Subject: [PATCH 116/219] mnt: Honor MNT_LOCKED when detaching mounts
-Cc: mpagano@gentoo.org
-
-commit ce07d891a0891d3c0d0c2d73d577490486b809e1 upstream.
-
-Modify umount(MNT_DETACH) to keep mounts in the hash table that are
-locked to their parent mounts, when the parent is lazily unmounted.
-
-In mntput_no_expire detach the children from the hash table, depending
-on mnt_pin_kill in cleanup_mnt to decrement the mnt_count of the children.
-
-In __detach_mounts if there are any mounts that have been unmounted
-but still are on the list of mounts of a mountpoint, remove their
-children from the mount hash table and those children to the unmounted
-list so they won't linger potentially indefinitely waiting for their
-final mntput, now that the mounts serve no purpose.

-commit f53e57975151f54ad8caa1b0ac8a78091cd5700a upstream.
-
-lookup_mountpoint can return either NULL or an error value.
-Update the test in __detach_mounts to test for an error value
-to avoid pathological cases causing a NULL pointer dereferences.
-
-The callers of __detach_mounts should prevent it from ever being
-called on an unlinked dentry but don't take any chances.

-Cc: mpagano@gentoo.org

-commit e0c9c0afd2fc958ffa34b697972721d81df8a56f upstream.
-
-Now that it is possible to lazily unmount an entire mount tree and
-leave the individual mounts connected to each other add a new flag
-UMOUNT_CONNECTED to umount_tree to force this behavior and use
-this flag in detach_mounts.
-
-This closes a bug where the deletion of a file or directory could
-trigger an unmount and reveal data under a mount point.

-Subject: [PATCH 119/219] tpm: fix: sanitized code paths in tpm_chip_register()
-Cc: mpagano@gentoo.org
-
-commit 34d47b6322087665be33ca3aa81775b143a4d7ac upstream.
-
-I started to work with PPI interface so that it would be available
-under character device sysfs directory and realized that chip
-registeration was still too messy.
-
-In TPM 1.x in some rare scenarios (errors that almost never occur)
-wrong order in deinitialization steps was taken in teardown. I
-reproduced these scenarios by manually inserting error codes in the
-place of the corresponding function calls.
-
-The key problem is that the teardown is messy with two separate code
-paths (this was inherited when moving code from tpm-interface.c).
-
-Moved TPM 1.x specific register/unregister functionality to own helper
-functions and added single code path for teardown in tpm_chip_register().
-Now the code paths have been fixed and it should be easier to review
-later on this part of the code.
-

- lib64 install dir
-Cc: mpagano@gentoo.org
-
-commit 76aea7731e7050c066943a1d7456ec6510702601 upstream.
-
-Commit:
-
- c6e5e9fbc3ea ("perf tools: Fix building error in x86_64 when dwarf unwind is on")
-
-removed the definition of IS_X86_64 but not all places using it, with
-the consequence that perf-read-vdsox32 would not be built anymore, and
-the default lib install directory was 'lib' instead of 'lib64'.
-
-Also needs to go to v3.19.

-Subject: [PATCH 124/219] tools lib traceevent kbuffer: Remove extra update to
- data pointer in PADDING
-Cc: mpagano@gentoo.org
-
-commit c5e691928bf166ac03430e957038b60adba3cf6c upstream.
-
-When a event PADDING is hit (a deleted event that is still in the ring
-buffer), translate_data() sets the length of the padding and also updates
-the data pointer which is passed back to the caller.
-
-This is unneeded because the caller also updates the data pointer with
-the passed back length. translate_data() should not update the pointer,
-only set the length.

-Subject: [PATCH 125/219] tools/power turbostat: Use $(CURDIR) instead of
- $(PWD) and add support for O= option in Makefile
-Cc: mpagano@gentoo.org
-
-commit f82263c6989c31ae9b94cecddffb29dcbec38710 upstream.
-
-Since commit ee0778a30153
-("tools/power: turbostat: make Makefile a bit more capable")
-turbostat's Makefile is using
-
- [...]
- BUILD_OUTPUT := $(PWD)
- [...]
-
-which obviously causes trouble when building "turbostat" with
-
- make -C /usr/src/linux/tools/power/x86/turbostat ARCH=x86 turbostat
-
-because GNU make does not update nor guarantee that $PWD is set.
-
-This patch changes the Makefile to use $CURDIR instead, which GNU make
-guarantees to set and update (i.e. when using "make -C ...") and also
-adds support for the O= option (see "make help" in your root of your
-kernel source tree for more details).

-Cc: mpagano@gentoo.org
-
-commit f16db8071ce18819fbd705ddcc91c6f392fb61f8 upstream.
-
-In some of the 'out_not_moved' error paths, lnum may be used
-uninitialized. Don't ignore the warning; let's fix it.
-
-This uninitialized variable doesn't have much visible effect in the end,
-since we just schedule the PEB for erasure, and its LEB number doesn't
-really matter (it just gets printed in debug messages). But let's get it
-straight anyway.

-Subject: [PATCH 131/219] iscsi-target: Convert iscsi_thread_set usage to
- kthread.h
-Cc: mpagano@gentoo.org
-
-commit 88dcd2dab5c23b1c9cfc396246d8f476c872f0ca upstream.
-
-This patch converts iscsi-target code to use modern kthread.h API
-callers for creating RX/TX threads for each new iscsi_conn descriptor,
-and releasing associated RX/TX threads during connection shutdown.
-
-This is done using iscsit_start_kthreads() -> kthread_run() to start
-new kthreads from within iscsi_post_login_handler(), and invoking
-kthread_stop() from existing iscsit_close_connection() code.
-
-Also, convert iscsit_logout_post_handler_closesession() code to use
-cmpxchg when determing when iscsit_cause_connection_reinstatement()
-needs to sleep waiting for completion.

-Subject: [PATCH 132/219] target: Fix COMPARE_AND_WRITE with SG_TO_MEM_NOALLOC
- handling
-Cc: mpagano@gentoo.org
-
-commit c8e639852ad720499912acedfd6b072325fd2807 upstream.
-
-This patch fixes a bug for COMPARE_AND_WRITE handling with
-fabrics using SCF_PASSTHROUGH_SG_TO_MEM_NOALLOC.
-
-It adds the missing allocation for cmd->t_bidi_data_sg within
-transport_generic_new_cmd() that is used by COMPARE_AND_WRITE
-for the initial READ payload, even if the fabric is already
-providing a pre-allocated buffer for cmd->t_data_sg.
-
-Also, fix zero-length COMPARE_AND_WRITE handling within the
-compare_and_write_callback() and target_complete_ok_work()
-to queue the response, skipping the initial READ.
-
-This fixes COMPARE_AND_WRITE emulation with loopback, vhost,
-and xen-backend fabric drivers using SG_TO_MEM_NOALLOC.

-Subject: [PATCH 133/219] target/file: Fix BUG() when CONFIG_DEBUG_SG=y and DIF
- protection enabled
-Cc: mpagano@gentoo.org
-
-commit 38da0f49e8aa1649af397d53f88e163d0e60c058 upstream.
-
-When CONFIG_DEBUG_SG=y and DIF protection support enabled, kernel
-BUG()s are triggered due to the following two issues:
-
-1) prot_sg is not initialized by sg_init_table().
-
-When CONFIG_DEBUG_SG=y, scatterlist helpers check sg entry has a
-correct magic value.
-
-2) vmalloc'ed buffer is passed to sg_set_buf().
-
-sg_set_buf() uses virt_to_page() to convert virtual address to struct
-page, but it doesn't work with vmalloc address. vmalloc_to_page()
-should be used instead. As prot_buf isn't usually too large, so
-fix it by allocating prot_buf by kmalloc instead of vmalloc.

-Subject: [PATCH 134/219] target/file: Fix UNMAP with DIF protection support
-Cc: mpagano@gentoo.org
-
-commit 64d240b721b21e266ffde645ec965c3b6d1c551f upstream.
-
-When UNMAP command is issued with DIF protection support enabled,
-the protection info for the unmapped region is remain unchanged.
-So READ command for the region causes data integrity failure.
-
-This fixes it by invalidating protection info for the unmapped region
-by filling with 0xff pattern. This change also adds helper function
-fd_do_prot_fill() in order to reduce code duplication with existing
-fd_format_prot().

-Subject: [PATCH 135/219] target/file: Fix SG table for prot_buf initialization
-Cc: mpagano@gentoo.org
-
-commit c836777830428372074d5129ac513e1472c99791 upstream.
-
-In fd_do_prot_rw(), it allocates prot_buf which is used to copy from
-se_cmd->t_prot_sg by sbc_dif_copy_prot(). The SG table for prot_buf
-is also initialized by allocating 'se_cmd->t_prot_nents' entries of
-scatterlist and setting the data length of each entry to PAGE_SIZE
-at most.
-
-However if se_cmd->t_prot_sg contains a clustered entry (i.e.
-sg->length > PAGE_SIZE), the SG table for prot_buf can't be
-initialized correctly and sbc_dif_copy_prot() can't copy to prot_buf.
-(This actually happened with TCM loopback fabric module)
-
-As prot_buf is allocated by kzalloc() and it's physically contiguous,
-we only need a single scatterlist entry.

-Cc: mpagano@gentoo.org
-
-commit 6d1966dfd6e0ad2f8aa4b664ae1a62e33abe1998 upstream.
-
-Register MIDR_EL1 is masked to get variant and revision fields, then
-compared against midr_range_min and midr_range_max when checking
-whether CPU is affected by any particular erratum. However, variant
-and revision fields in MIDR_EL1 are separated by 16 bits, so the min
-and max of midr range should be constructed accordingly, otherwise
-the patch will not be applied when variant field is non-0.

-Subject: [PATCH 140/219] arm64: head.S: ensure visibility of page tables
-Cc: mpagano@gentoo.org
-
-commit 91d57155dc5ab4b311624b7ee570339b6af19ad5 upstream.
-
-After writing the page tables, we use __inval_cache_range to invalidate
-any stale cache entries. Strongly Ordered memory accesses are not
-ordered w.r.t. cache maintenance instructions, and hence explicit memory
-barriers are required to provide this ordering. However,
-__inval_cache_range was written to be used on Normal Cacheable memory
-once the MMU and caches are on, and does not have any barriers prior to
-the DC instructions.
-
-This patch adds a DMB between the page tables being written and the
-corresponding cachelines being invalidated, ensuring that the
-invalidation makes the new data visible to subsequent cacheable
-accesses. A barrier is not required before the prior invalidate as we do
-not access the page table memory area prior to this, and earlier
-barriers in preserve_boot_args and set_cpu_boot_mode_flag ensures
-ordering w.r.t. any stores performed prior to entering Linux.

-Subject: [PATCH 141/219] arm64: Adjust EFI libstub object include logic
-Cc: mpagano@gentoo.org
-
-commit ad08fd494bf00c03ae372e0bbd9cefa37bf608d6 upstream.
-
-Commit f4f75ad5 ("efi: efistub: Convert into static library")
-introduced a static library for EFI stub, libstub.
-
-The EFI libstub directory is referenced by the kernel build system via
-a obj subdirectory rule in:
-drivers/firmware/efi/Makefile
-
-Unfortunately, arm64 also references the EFI libstub via:
-libs-$(CONFIG_EFI_STUB) += drivers/firmware/efi/libstub/
-
-If we're unlucky, the kernel build system can enter libstub via two
-simultaneous threads resulting in build failures such as:
-
-fixdep: error opening depfile: drivers/firmware/efi/libstub/.efi-stub-helper.o.d: No such file or directory
-scripts/Makefile.build:257: recipe for target 'drivers/firmware/efi/libstub/efi-stub-helper.o' failed
-make[1]: *** [drivers/firmware/efi/libstub/efi-stub-helper.o] Error 2
-Makefile:939: recipe for target 'drivers/firmware/efi/libstub' failed
-make: *** [drivers/firmware/efi/libstub] Error 2
-make: *** Waiting for unfinished jobs....
-
-This patch adjusts the arm64 Makefile to reference the compiled library
-explicitly (as is currently done in x86), rather than the directory.

-Subject: [PATCH 142/219] arm64: apply alternatives for !SMP kernels
-Cc: mpagano@gentoo.org
-
-commit 137650aad96c9594683445e41afa8ac5a2097520 upstream.
-
-Currently we only perform alternative patching for kernels built with
-CONFIG_SMP, as we call apply_alternatives_all() in smp.c, which is only
-built for CONFIG_SMP. Thus !SMP kernels may not have necessary
-alternatives patched in.
-
-This patch ensures that we call apply_alternatives_all() once all CPUs
-are booted, even for !SMP kernels, by having the smp_init_cpus() stub
-call this for !SMP kernels via up_late_init. A new wrapper,
-do_post_cpus_up_work, is added so we can hook other calls here later
-(e.g. boot mode logging).

- #845719
-Cc: mpagano@gentoo.org
-
-commit 905e8c5dcaa147163672b06fe9dcb5abaacbc711 upstream.
-
-When running a compat (AArch32) userspace on Cortex-A53, a load at EL0
-from a virtual address that matches the bottom 32 bits of the virtual
-address used by a recent load at (AArch64) EL1 might return incorrect
-data.
-
-This patch works around the issue by writing to the contextidr_el1
-register on the exception return path when returning to a 32-bit task.
-This workaround is patched in at runtime based on the MIDR value of the
-processor.

-Subject: [PATCH 144/219] powerpc/powernv: Don't map M64 segments using M32DT
-Cc: mpagano@gentoo.org
-
-commit 027fa02f84e851e21daffdf8900d6117071890f8 upstream.
-
-If M64 has been supported, the prefetchable 64-bits memory resources
-shouldn't be mapped to the corresponding PE# via M32DT. Unfortunately,
-we're doing that in pnv_ioda_setup_pe_seg() wrongly. The issue was
-introduced by commit 262af55 ("powerpc/powernv: Enable M64 aperatus
-for PHB3"). The patch fixes the issue by simply skipping M64 resources
-when updating to M32DT.

-Subject: [PATCH 145/219] powerpc: Fix missing L2 cache size in
- /sys/devices/system/cpu
-Cc: mpagano@gentoo.org
-
-commit f7e9e358362557c3aa2c1ec47490f29fe880a09e upstream.
-
-This problem appears to have been introduced in 2.6.29 by commit
-93197a36a9c1 "Rewrite sysfs processor cache info code".
-
-This caused lscpu to error out on at least e500v2 devices, eg:
-
- error: cannot open /sys/devices/system/cpu/cpu0/cache/index2/size: No such file or directory
-
-Some embedded powerpc systems use cache-size in DTS for the unified L2
-cache size, not d-cache-size, so we need to allow for both DTS names.
-Added a new CACHE_TYPE_UNIFIED_D cache_type_info structure to handle
-this.
-
-Fixes: 93197a36a9c1 ("powerpc: Rewrite sysfs processor cache info code")

-Cc: mpagano@gentoo.org
-
-commit b0dd00addc5035f87ec9c5820dacc1ebc7fcb3e6 upstream.
-
-The conversion from __get_cpu_var() to this_cpu_ptr() in iic_setup_cpu()
-is wrong. It causes an oops at boot.
-
-We need the per-cpu address of struct cpu_iic, not cpu_iic.regs->prio.
-
-Sparse noticed this, because we pass a non-iomem pointer to out_be64(),
-but we obviously don't check the sparse results often enough.

-Cc: mpagano@gentoo.org
-
-commit 74ff960222d90999508b4ba0d3449f796695b6d5 upstream.
-
-The delay time after a reset in the codec probe callback was too short,
-and did not work on certain hw because the codec needs more time to
-power on. This increases the delay time from 1us to 1ms.

-Subject: [PATCH 149/219] ASoC: wm8741: Fix rates constraints values
-Cc: mpagano@gentoo.org
-
-commit 8787041d9bb832b9449b1eb878cedcebce42c61a upstream.
-
-The WM8741 DAC supports the following typical audio sampling rates:
- 44.1kHz, 88.2kHz, 176.4kHz (eg: with a master clock of 22.5792MHz)
- 32kHz, 48kHz, 96kHz, 192kHz (eg: with a master clock of 24.576MHz)
-
-For the rates lists, we should use 82000 instead of 88235, 176400
-instead of 1764000 and 192000 instead of 19200 (seems to be a typo).

-Subject: [PATCH 153/219] ACPICA: Utilities: split IO address types from data
- type models.
-Cc: mpagano@gentoo.org
-
-commit 2b8760100e1de69b6ff004c986328a82947db4ad upstream.
-
-ACPICA commit aacf863cfffd46338e268b7415f7435cae93b451
-
-It is reported that on a physically 64-bit addressed machine, 32-bit kernel
-can trigger crashes in accessing the memory regions that are beyond the
-32-bit boundary. The region field's start address should still be 32-bit
-compliant, but after a calculation (adding some offsets), it may exceed the
-32-bit boundary. This case is rare and buggy, but there are real BIOSes
-leaked with such issues (see References below).
-
-This patch fixes this gap by always defining IO addresses as 64-bit, and
-allows OSPMs to optimize it for a real 32-bit machine to reduce the size of
-the internal objects.
-
-Internal acpi_physical_address usages in the structures that can be fixed
-by this change include:
- 1. struct acpi_object_region:
- acpi_physical_address address;
- 2. struct acpi_address_range:
- acpi_physical_address start_address;
- acpi_physical_address end_address;
- 3. struct acpi_mem_space_context;
- acpi_physical_address address;
- 4. struct acpi_table_desc
- acpi_physical_address address;
-See known issues 1 for other usages.
-
-Note that acpi_io_address which is used for ACPI_PROCESSOR may also suffer
-from same problem, so this patch changes it accordingly.
-
-For iasl, it will enforce acpi_physical_address as 32-bit to generate
-32-bit OSPM compatible tables on 32-bit platforms, we need to define
-ACPI_32BIT_PHYSICAL_ADDRESS for it in acenv.h.
-
-Known issues:
- 1. Cleanup of mapped virtual address
- In struct acpi_mem_space_context, acpi_physical_address is used as a virtual
- address:
- acpi_physical_address mapped_physical_address;
- It is better to introduce acpi_virtual_address or use acpi_size instead.
- This patch doesn't make such a change. Because this should be done along
- with a change to acpi_os_map_memory()/acpi_os_unmap_memory().
- There should be no functional problem to leave this unchanged except
- that only this structure is enlarged unexpectedly.

-ACPICA commit c70434d4da13e65b6163c79a5aa16b40193631c7
-
-ACPI_MTX_TABLES is acquired and released by the callers of
-acpi_tb_install_standard_table() so releasing it in the function itself is
-causing the following error in Linux kernel if the table is reloaded:
-
-ACPI Error: Mutex [0x2] is not acquired, cannot release (20141107/utmutex-321)
-Call Trace:

-Subject: [PATCH 155/219] ACPICA: Store GPE register enable masks upfront
-Cc: mpagano@gentoo.org
-
-commit 0ee0d34985ceffe4036319e1e46df8bff591b9e3 upstream.
-
-It is reported that ACPI interrupts do not work any more on
-Dell Latitude D600 after commit c50f13c672df (ACPICA: Save
-current masks of enabled GPEs after enable register writes).
-The problem turns out to be related to the fact that the
-enable_mask and enable_for_run GPE bit masks are not in
-sync (in the absence of any system suspend/resume events)
-for at least one GPE register on that machine.
-
-Address this problem by writing the enable_for_run mask into
-enable_mask as soon as enable_for_run is updated instead of
-doing that only after the subsequent register write has
-succeeded. For consistency, update acpi_hw_gpe_enable_write()
-to store the bit mask to be written into the GPE register
-in enable_mask unconditionally before the write.
-
-Since the ACPI_GPE_SAVE_MASK flag is not necessary any more after
-that, drop it along with the symbols depending on it.
-

-Subject: [PATCH 158/219] xtensa: provide __NR_sync_file_range2 instead of
- __NR_sync_file_range
-Cc: mpagano@gentoo.org
-
-commit 01e84c70fe40c8111f960987bcf7f931842e6d07 upstream.
-
-xtensa actually uses sync_file_range2 implementation, so it should
-define __NR_sync_file_range2 as other architectures that use that
-function. That fixes userspace interface (that apparently never worked)
-and avoids special-casing xtensa in libc implementations.
-See the thread ending at
-http://lists.busybox.net/pipermail/uclibc/2015-February/048833.html
-for more details.

-Cc: mpagano@gentoo.org
-
-commit 24e94454c8cb6a13634f5a2f5a01da53a546a58d upstream.
-
-- don't lock lp->lock in the iss_net_timer for the call of iss_net_poll,
- it will lock it itself;
-- invert order of lp->lock and opened_lock acquisition in the
- iss_net_open to make it consistent with iss_net_poll;
-- replace spin_lock with spin_lock_bh when acquiring locks used in
- iss_net_timer from non-atomic context;
-- replace spin_lock_irqsave with spin_lock_bh in the iss_net_start_xmit
- as the driver doesn't use lp->lock in the hard IRQ context;
-- replace __SPIN_LOCK_UNLOCKED(lp.lock) with spin_lock_init, otherwise
- lockdep is unhappy about using non-static key.

-Subject: [PATCH 160/219] gpio: mvebu: Fix mask/unmask managment per irq chip
- type
-Cc: mpagano@gentoo.org
-
-commit 61819549f572edd7fce53f228c0d8420cdc85f71 upstream.
-
-Level IRQ handlers and edge IRQ handler are managed by tow different
-sets of registers. But currently the driver uses the same mask for the
-both registers. It lead to issues with the following scenario:
-
-First, an IRQ is requested on a GPIO to be triggered on front. After,
-this an other IRQ is requested for a GPIO of the same bank but
-triggered on level. Then the first one will be also setup to be
-triggered on level. It leads to an interrupt storm.
-
-The different kind of handler are already associated with two
-different irq chip type. With this patch the driver uses a private
-mask for each one which solves this issue.
-
-It has been tested on an Armada XP based board and on an Armada 375
-board. For the both boards, with this patch is applied, there is no
-such interrupt storm when running the previous scenario.
-
-This bug was already fixed but in a different way in the legacy
-version of this driver by Evgeniy Dushistov:
-9ece8839b1277fb9128ff6833411614ab6c88d68 "ARM: orion: Fix for certain
-sequence of request_irq can cause irq storm". The fact the new version
-of the gpio drive could be affected had been discussed there:
-http://thread.gmane.org/gmane.linux.ports.arm.kernel/344670/focus=364012

-Cc: mpagano@gentoo.org
-
-commit 3a9e9cb65be84d6c64fbe9c69a73c15d59f29454 upstream.
-
-Commit 42773b28e71d ("clk: samsung: exynos4: Enable ARMCLK
-down feature") enabled ARMCLK down feature on all Exynos4
-SoCs. Unfortunately on Exynos4210 SoC ARMCLK down feature
-causes a lockup when ondemand cpufreq governor is used.
-Fix it by limiting ARMCLK down feature to Exynos4x12 SoCs.
-
-This patch was tested on:
-- Exynos4210 SoC based Trats board
-- Exynos4210 SoC based Origen board
-- Exynos4412 SoC based Trats2 board
-- Exynos4412 SoC based Odroid-U3 board

-Cc: mpagano@gentoo.org
-
-commit 5e43e259171e1eee8bc074d9c44be434e685087b upstream.
-
-The number of resets controls is 32 times the number of peripheral
-register banks rather than 32 times the number of clocks. This reduces
-(drastically) the number of reset controls registered from 10080 (315
-clocks * 32) to 224 (6 peripheral register banks * 32).
-
-This also fixes a potential crash because trying to use any of the
-excess reset controls (224-10079) would have caused accesses beyond
-the array bounds of the peripheral register banks definition array.

-Subject: [PATCH 165/219] clk: qcom: Properly change rates for ahbix clock
-Cc: mpagano@gentoo.org
-
-commit 9d3745d44a7faa7d24db7facb1949a1378162f3e upstream.
-
-The ahbix clock can never be turned off in practice. To change the
-rates we need to switch the mux off the M/N counter to an always on
-source (XO), reprogram the M/N counter to get the rate we want and
-finally switch back to the M/N counter. Add a new ops structure
-for this type of clock so that we can set the rate properly.

-Subject: [PATCH 166/219] clk: qcom: fix RCG M/N counter configuration
-Cc: mpagano@gentoo.org
-
-commit 0b21503dbbfa669dbd847b33578d4041513cddb2 upstream.
-
-Currently, a RCG's M/N counter (used for fraction division) is
-set to either 'bypass' (counter disabled) or 'dual edge' (counter
-enabled) based on whether the corresponding rcg struct has a mnd
-field specified and a non-zero N.
-
-In the case where M and N are the same value, the M/N counter is
-still enabled by code even though no division takes place.
-Leaving the RCG in such a state can result in improper behavior.
-This was observed with the DSI pixel clock RCG when M and N were
-both set to 1.
-
-Add an additional check (M != N) to enable the M/N counter only
-when it's needed for fraction division.

-Subject: [PATCH 168/219] dm crypt: fix deadlock when async crypto algorithm
- returns -EBUSY
-Cc: mpagano@gentoo.org
-
-commit 0618764cb25f6fa9fb31152995de42a8a0496475 upstream.
-
-I suspect this doesn't show up for most anyone because software
-algorithms typically don't have a sense of being too busy. However,
-when working with the Freescale CAAM driver it will return -EBUSY on
-occasion under heavy -- which resulted in dm-crypt deadlock.
-
-After checking the logic in some other drivers, the scheme for
-crypt_convert() and it's callback, kcryptd_async_done(), were not
-correctly laid out to properly handle -EBUSY or -EINPROGRESS.
-
-Fix this by using the completion for both -EBUSY and -EINPROGRESS. Now
-crypt_convert()'s use of completion is comparable to
-af_alg_wait_for_completion(). Similarly, kcryptd_async_done() follows
-the pattern used in af_alg_complete().
-
-Before this fix dm-crypt would lockup within 1-2 minutes running with
-the CAAM driver. Fix was regression tested against software algorithms
-on PPC32 and x86_64, and things seem perfectly happy there as well.

-Subject: [PATCH 175/219] mvsas: fix panic on expander attached SATA devices
-Cc: mpagano@gentoo.org
-
-commit 56cbd0ccc1b508de19561211d7ab9e1c77e6b384 upstream.
-
-mvsas is giving a General protection fault when it encounters an expander
-attached ATA device. Analysis of mvs_task_prep_ata() shows that the driver is
-assuming all ATA devices are locally attached and obtaining the phy mask by
-indexing the local phy table (in the HBA structure) with the phy id. Since
-expanders have many more phys than the HBA, this is causing the index into the
-HBA phy table to overflow and returning rubbish as the pointer.
-
-mvs_task_prep_ssp() instead does the phy mask using the port properties.
-Mirror this in mvs_task_prep_ata() to fix the panic.

-commit 8abaae62f3fdead8f4ce0ab46b4ab93dee39bab2 upstream.
-
-If ib_umem_get() is called with a size equal to 0 and an
-non-page aligned address, one page will be pinned and a
-0-sized umem will be returned to the caller.
-
-This should not be allowed: it's not expected for a memory

-
-This patch adds a check to explicitly refuse to register
-a 0-sized region.

- at 0x0
-Cc: mpagano@gentoo.org
-
-commit 66578b0b2f69659f00b6169e6fe7377c4b100d18 upstream.
-
-In a call to ib_umem_get(), if address is 0x0 and size is
-already page aligned, check added in commit 8494057ab5e4
-("IB/uverbs: Prevent integer overflow in ib_umem_get address
-arithmetic") will refuse to register a memory region that
-could otherwise be valid (provided vm.mmap_min_addr sysctl
-and mmap_low_allowed SELinux knobs allow userspace to map
-something at address 0x0).
-
-This patch allows back such registration: ib_umem_get()
-should probably don't care of the base address provided it
-can be pinned with get_user_pages().
-
-There's two possible overflows, in (addr + size) and in
-PAGE_ALIGN(addr + size), this patch keep ensuring none
-of them happen while allowing to pin memory at address
-0x0. Anyway, the case of size equal 0 is no more (partially)
-handled as 0-length memory region are disallowed by an
-earlier check.

-Cc: mpagano@gentoo.org
-
-commit ca9b590caa17bcbbea119594992666e96cde9c2f upstream.
-
-The current code decreases from the mss size (which is the gso_size
-from the kernel skb) the size of the packet headers.
-
-It shouldn't do that because the mss that comes from the stack
-(e.g IPoIB) includes only the tcp payload without the headers.
-
-The result is indication to the HW that each packet that the HW sends
-is smaller than what it could be, and too many packets will be sent
-for big messages.
-
-An easy way to demonstrate one more aspect of the problem is by
-configuring the ipoib mtu to be less than 2*hlen (2*56) and then
-run app sending big TCP messages. This will tell the HW to send packets
-with giant (negative value which under unsigned arithmetics becomes
-a huge positive one) length and the QP moves to SQE state.

-Subject: [PATCH 183/219] tracing: Fix incorrect enabling of trace events by
- boot cmdline
-Cc: mpagano@gentoo.org
-
-commit 84fce9db4d7eaebd6cb2ee30c15da6d4e4daf846 upstream.
-
-There is a problem that trace events are not properly enabled with
-boot cmdline. The problem is that if we pass "trace_event=kmem:mm_page_alloc"
-to the boot cmdline, it enables all kmem trace events, and not just
-the page_alloc event.
-
-This is caused by the parsing mechanism. When we parse the cmdline, the buffer
-contents is modified due to tokenization. And, if we use this buffer
-again, we will get the wrong result.
-
-Unfortunately, this buffer is be accessed three times to set trace events
-properly at boot time. So, we need to handle this situation.
-
-There is already code handling ",", but we need another for ":".
-This patch adds it.

-Cc: mpagano@gentoo.org
-
-commit 133778482ec6c8fde69406be380333963627c17a upstream.
-
-Those symlinks are created for the mux_dev, so we need to remove it from
-there. Currently, it breaks for muxes where the mux_dev is not the device
-of the parent adapter like this:
-
-[ 78.234644] WARNING: CPU: 0 PID: 365 at fs/sysfs/dir.c:31 sysfs_warn_dup+0x5c/0x78()
-[ 78.242438] sysfs: cannot create duplicate filename '/devices/platform/i2cbus@8/channel-0'
-
-Remove confusing comments while we are here.

-Subject: [PATCH 186/219] i2c: Mark adapter devices with
- pm_runtime_no_callbacks
-Cc: mpagano@gentoo.org
-
-commit 6ada5c1e1b077ab98fc144d7ac132b4dcc0148ec upstream.
-
-Commit 523c5b89640e ("i2c: Remove support for legacy PM") removed the PM
-ops from the bus type, which causes the pm operations on the s3c2410
-adapter device to fail (-ENOSUPP in rpm_callback). The adapter device
-doesn't get bound to a driver and as such can't have its own pm_runtime
-callbacks. Previously this was fine as the bus callbacks would have been
-used, but now this can cause devices which use PM runtime and are
-attached over I2C to fail to resume.
-
-This commit fixes this issue by marking all adapter devices with
-pm_runtime_no_callbacks, since they can't have any.

-Subject: [PATCH 189/219] drm/exynos: Enable DP clock to fix display on
- Exynos5250 and other
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-Cc: mpagano@gentoo.org
-
-commit 1c363c7cccf64128087002b0779986ad16aff6dc upstream.
-
-After adding display power domain for Exynos5250 in commit
-2d2c9a8d0a4f ("ARM: dts: add display power domain for exynos5250") the
-display on Chromebook Snow and others stopped working after boot.
-
-The reason for this suggested Andrzej Hajda: the DP clock was disabled.
-This clock is required by Display Port and is enabled by bootloader.
-However when FIMD driver probing was deferred, the display power domain
-was turned off. This effectively reset the value of DP clock enable
-register.
-
-When exynos-dp is later probed, the clock is not enabled and display is
-not properly configured:
-
-exynos-dp 145b0000.dp-controller: Timeout of video streamclk ok
-exynos-dp 145b0000.dp-controller: unable to config video
-
-Fixes: 2d2c9a8d0a4f ("ARM: dts: add display power domain for exynos5250")

- drm/i915: Stop gathering error states for CS error interrupts
-
-but just clearing is apparently not enough: A sufficiently dead gpu
-left behind by firmware (*cough* coreboot *cough*) can keep the gpu in
-an endless loop of such interrupts, eventually leading to the nmi
-firing. And definitely to what looks like a machine hang.
-
-Since we don't even enable these interrupts on gen5+ let's do the same
-on earlier platforms.

-Subject: [PATCH 192/219] drm: adv7511: Fix nested sleep when reading EDID
-Cc: mpagano@gentoo.org
-
-commit a5241289c4139f0521b89e34a70f5f998463ae15 upstream.
-
-The EDID read code waits for the read completion interrupt to occur
-using wait_event_interruptible(). The condition passed to the macro
-reads I2C registers. This results in sleeping with the task state set
-to TASK_INTERRUPTIBLE, triggering a WARN_ON() introduced in commit
-8eb23b9f35aae ("sched: Debug nested sleeps").
-
-Fix this by reworking the EDID read code. Instead of checking whether
-the read is complete through I2C reads, handle the interrupt registers
-in the interrupt handler and update a new edid_read flag accordingly. As
-a side effect both the IRQ and polling code paths now process the
-interrupt sources through the same code path, simplifying the code.

-I noticed this only by reading the code. To my knowledge it shouldn't

-Subject: [PATCH 194/219] drm/i915: cope with large i2c transfers
-Cc: mpagano@gentoo.org
-
-commit 9535c4757b881e06fae72a857485ad57c422b8d2 upstream.
-
-The hardware, according to the specs, is limited to 256 byte transfers,
-and current driver has no protections in case users attempt to do larger
-transfers. The code will just stomp over status register and mayhem
-ensues.
-
-Let's split larger transfers into digestable chunks. Doing this allows
-Atmel MXT driver on Pixel 1 function properly (it hasn't since commit
-9d8dc3e529a19e427fd379118acd132520935c5d "Input: atmel_mxt_ts -
-implement T44 message handling" which tries to consume multiple
-touchscreen/touchpad reports in a single transaction).

-Subject: [PATCH 195/219] RCU pathwalk breakage when running into a symlink
- overmounting something
-Cc: mpagano@gentoo.org
-
-commit 3cab989afd8d8d1bc3d99fef0e7ed87c31e7b647 upstream.
-
-Calling unlazy_walk() in walk_component() and do_last() when we find
-a symlink that needs to be followed doesn't acquire a reference to vfsmount.
-That's fine when the symlink is on the same vfsmount as the parent directory
-(which is almost always the case), but it's not always true - one _can_
-manage to bind a symlink on top of something. And in such cases we end up
-with excessive mntput().

-Subject: [PATCH 196/219] Revert "nfs: replace nfs_add_stats with nfs_inc_stats
- when add one"
-Cc: mpagano@gentoo.org
-
-commit 3708f842e107b9b79d54a75d152e666b693649e8 upstream.
-
-This reverts commit 5a254d08b086d80cbead2ebcee6d2a4b3a15587a.
-
-Since commit 5a254d08b086 ("nfs: replace nfs_add_stats with
-nfs_inc_stats when add one"), nfs_readpage and nfs_do_writepage use
-nfs_inc_stats to increment NFSIOS_READPAGES and NFSIOS_WRITEPAGES
-instead of nfs_add_stats.
-
-However nfs_inc_stats does not do the same thing as nfs_add_stats with
-value 1 because these functions work on distinct stats:
-nfs_inc_stats increments stats from "enum nfs_stat_eventcounters" (in
-server->io_stats->events) and nfs_add_stats those from "enum
-nfs_stat_bytecounters" (in server->io_stats->bytes).

-Cc: mpagano@gentoo.org
-
-commit 5ba4a25ab7b13be528b23f85182f4d09cf7f71ad upstream.
-
-vfs_fallocate will hit a NULL dereference if the client tries an
-ALLOCATE or DEALLOCATE with a special stateid. Fix that. (We also
-depend on the open to have broken any conflicting leases or delegations
-for us.)
-
-(If it turns out we need to allow special stateid's then we could do a
-temporary open here in the special-stateid case, as we do for read and
-write. For now I'm assuming it's not necessary.)

-Subject: [PATCH 201/219] nfsd: fix nsfd startup race triggering BUG_ON
-Cc: mpagano@gentoo.org
-
-commit bb7ffbf29e76b89a86ca4c3ee0d4690641f2f772 upstream.
-
-nfsd triggered a BUG_ON in net_generic(...) when rpc_pipefs_event(...)
-in fs/nfsd/nfs4recover.c was called before assigning ntfsd_net_id.
-The following was observed on a MIPS 32-core processor:
-kernel: Call Trace:
-kernel: [<ffffffffc00bc5e4>] rpc_pipefs_event+0x7c/0x158 [nfsd]
-kernel: [<ffffffff8017a2a0>] notifier_call_chain+0x70/0xb8

-kernel:
-kernel:
- Code: 0040f809 00000000 2e020001 <00020336> 3c12c00d
- 3c02801a de100000 6442eb98 0040f809
-kernel: ---[ end trace 7471374335809536 ]---
-
-Fixed this behaviour by calling register_pernet_subsys(&nfsd_net_ops) before
-registering rpc_pipefs_event(...) with the notifier chain.

- sleeping
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-Cc: mpagano@gentoo.org
-
-commit 5d05e54af3cdbb13cf19c557ff2184781b91a22c upstream.
-
-Chuck pointed out a problem that crept in with commit 6ffa30d3f734 (nfs:
-don't call blocking operations while !TASK_RUNNING). Linux counts tasks
-in uninterruptible sleep against the load average, so this caused the
-system's load average to be pinned at at least 1 when there was a
-NFSv4.1+ mount active.
-
-Not a huge problem, but it's probably worth fixing before we get too
-many complaints about it. This patch converts the code back to use
-TASK_INTERRUPTIBLE sleep, simply has it flush any signals on each loop
-iteration. In practice no one should really be signalling this thread at
-all, so I think this is reasonably safe.
-
-With this change, there's also no need to game the hung task watchdog so
-we can also convert the schedule_timeout call back to a normal schedule.

-Subject: [PATCH 203/219] nfs: fix DIO good bytes calculation
-Cc: mpagano@gentoo.org
-
-commit 1ccbad9f9f9bd36db26a10f0b17fbaf12b3ae93a upstream.
-
-For direct read that has IO size larger than rsize, we'll split
-it into several READ requests and nfs_direct_good_bytes() would
-count completed bytes incorrectly by eating last zero count reply.
-
-Fix it by handling mirror and non-mirror cases differently such that
-we only count mirrored writes differently.
-
-This fixes 5fadeb47("nfs: count DIO good bytes correctly with mirroring").

-d4b18c3e (pnfs: remove GETDEVICELIST implementation) removed the

-Cc: mpagano@gentoo.org
-
-commit 4cd57f97135840f637431c92380c8da3edbe44ed upstream.
-
-dl_task_timer() may fire on a different rq from where a task was removed
-after throttling. Since the call path is:
-
- dl_task_timer() ->
- enqueue_task_dl() ->
- enqueue_dl_entity() ->
- replenish_dl_entity()
-
-and replenish_dl_entity() uses dl_se's rq, we can't use current's rq
-in dl_task_timer(), but we need to lock the task's previous one.

-Subject: [PATCH 207/219] e1000: add dummy allocator to fix race condition
- between mtu change and netpoll
-Cc: mpagano@gentoo.org
-
-commit 08e8331654d1d7b2c58045e549005bc356aa7810 upstream.
-
-There is a race condition between e1000_change_mtu's cleanups and
-netpoll, when we change the MTU across jumbo size:
-
-Changing MTU frees all the rx buffers:
- e1000_change_mtu -> e1000_down -> e1000_clean_all_rx_rings ->
- e1000_clean_rx_ring
-
-Then, close to the end of e1000_change_mtu:
- pr_info -> ... -> netpoll_poll_dev -> e1000_clean ->
- e1000_clean_rx_irq -> e1000_alloc_rx_buffers -> e1000_alloc_frag
-
-And when we come back to do the rest of the MTU change:
- e1000_up -> e1000_configure -> e1000_configure_rx ->
- e1000_alloc_jumbo_rx_buffers
-
-alloc_jumbo finds the buffers already != NULL, since data (shared with
-page in e1000_rx_buffer->rxbuf) has been re-alloc'd, but it's garbage,
-or at least not what is expected when in jumbo state.
-
-This results in an unusable adapter (packets don't get through), and a
-NULL pointer dereference on the next call to e1000_clean_rx_ring
-(other mtu change, link down, shutdown):
-
-BUG: unable to handle kernel NULL pointer dereference at (null)
-IP: [<ffffffff81194d6e>] put_compound_page+0x7e/0x330
-
- [...]
-
-Call Trace:
- [<ffffffff81195445>] put_page+0x55/0x60
- [<ffffffff815d9f44>] e1000_clean_rx_ring+0x134/0x200

- [<ffffffff81663802>] rtnetlink_rcv_msg+0x92/0x260
-
-By setting the allocator to a dummy version, netpoll can't mess up our
-rx buffers. The allocator is set back to a sane value in
-e1000_configure_rx.

-Subject: [PATCH 209/219] ebpf: verifier: check that call reg with ARG_ANYTHING
- is initialized
-Cc: mpagano@gentoo.org
-
-commit 80f1d68ccba70b1060c9c7360ca83da430f66bed upstream.
-
-I noticed that a helper function with argument type ARG_ANYTHING does
-not need to have an initialized value (register).
-
-This can worst case lead to unintented stack memory leakage in future
-helper functions if they are not carefully designed, or unintended
-application behaviour in case the application developer was not careful
-enough to match a correct helper function signature in the API.
-
-The underlying issue is that ARG_ANYTHING should actually be split
-into two different semantics:
-
- 1) ARG_DONTCARE for function arguments that the helper function
- does not care about (in other words: the default for unused
- function arguments), and
-
- 2) ARG_ANYTHING that is an argument actually being used by a
- helper function and *guaranteed* to be an initialized register.
-
-The current risk is low: ARG_ANYTHING is only used for the 'flags'
-argument (r4) in bpf_map_update_elem() that internally does strict
-checking.

-Subject: [PATCH 210/219] mm, thp: really limit transparent hugepage allocation
- to local node
-Cc: mpagano@gentoo.org
-
-commit 5265047ac30191ea24b16503165000c225f54feb upstream.
-
-Commit 077fcf116c8c ("mm/thp: allocate transparent hugepages on local
-node") restructured alloc_hugepage_vma() with the intent of only
-allocating transparent hugepages locally when there was not an effective
-interleave mempolicy.
-
-alloc_pages_exact_node() does not limit the allocation to the single node,
-however, but rather prefers it. This is because __GFP_THISNODE is not set
-which would cause the node-local nodemask to be passed. Without it, only
-a nodemask that prefers the local node is passed.
-
-Fix this by passing __GFP_THISNODE and falling back to small pages when
-the allocation fails.
-
-Commit 9f1b868a13ac ("mm: thp: khugepaged: add policy for finding target
-node") suffers from a similar problem for khugepaged, which is also fixed.
-
-Fixes: 077fcf116c8c ("mm/thp: allocate transparent hugepages on local node")
-Fixes: 9f1b868a13ac ("mm: thp: khugepaged: add policy for finding target node")

-Cc: mpagano@gentoo.org
-
-commit 0b053c9518292705736329a8fe20ef4686ffc8e9 upstream.
-
-OPTIMIZER_HIDE_VAR(), as defined when using gcc, is insufficient to
-ensure protection from dead store optimization.
-
-For the random driver and crypto drivers, calls are emitted ...
-
- $ gdb vmlinux
- (gdb) disassemble memzero_explicit
- Dump of assembler code for function memzero_explicit:

-
-... but in case in future we might use facilities such as LTO, then
-OPTIMIZER_HIDE_VAR() is not sufficient to protect gcc from a possible
-eviction of the memset(). We have to use a compiler barrier instead.
-
-Minimal test example when we assume memzero_explicit() would *not* be
-a call, but would have been *inlined* instead:
-
- static inline void memzero_explicit(void *s, size_t count)

- <foo>
- }
-
- int main(void)
- {
- char buff[20];
-
- snprintf(buff, sizeof(buff) - 1, "test");
- printf("%s", buff);
-
- memzero_explicit(buff, sizeof(buff));
- return 0;
- }
-

- really is
-Cc: mpagano@gentoo.org
-
-commit a3fa71c40f1853d0c27e8f5bc01a722a705d9682 upstream.
-
-In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
-array, not a number. This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
-used to display this field in debugfs (it would display a pointer, not
-the actual data). Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.
-
-This bug has been found by adding a __printf attribute to
-wl1271_format_buffer. gcc complained about "format '%u' expects
-argument of type 'unsigned int', but argument 5 has type 'u32 *'".

-Subject: [PATCH 213/219] crypto: omap-aes - Fix support for unequal lengths
-Cc: mpagano@gentoo.org
-
-commit 6d7e7e02a044025237b6f62a20521170b794537f upstream.
-
-For cases where total length of an input SGs is not same as
-length of the input data for encryption, omap-aes driver
-crashes. This happens in the case when IPsec is trying to use
-omap-aes driver.
-
-To avoid this, we copy all the pages from the input SG list
-into a contiguous buffer and prepare a single element SG list
-for this buffer with length as the total bytes to crypt, which is
-similar thing that is done in case of unaligned lengths.
-
-Fixes: 6242332ff2f3 ("crypto: omap-aes - Add support for cases of unaligned lengths")

-Cc: mpagano@gentoo.org
-
-commit f4831605f2dacd12730fe73961c77253cc2ea425 upstream.
-
-time_init invokes timer64_init (which is __init annotation)
-since all of these are invoked at init time, lets maintain
-consistency by ensuring time_init is marked appropriately
-as well.
-
-This fixes the following warning with CONFIG_DEBUG_SECTION_MISMATCH=y
-
-WARNING: vmlinux.o(.text+0x3bfc): Section mismatch in reference from the function time_init() to the function .init.text:timer64_init()
-The function time_init() references
-the function __init timer64_init().
-This is often because time_init lacks a __init
-annotation or the annotation of timer64_init is wrong.

-Subject: [PATCH 216/219] drivers: platform: parse IRQ flags from resources
-Cc: mpagano@gentoo.org
-
-commit 7085a7401ba54e92bbb5aa24d6f428071e18e509 upstream.
-
-This fixes a regression from the net subsystem:
-After commit d52fdbb735c36a209f36a628d40ca9185b349ba7
-"smc91x: retrieve IRQ and trigger flags in a modern way"
-a regression would appear on some legacy platforms such
-as the ARM PXA Zylonite that specify IRQ resources like
-this:
-
-static struct resource r = {
- .start = X,
- .end = X,
- .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHEDGE,
-};
-
-The previous code would retrieve the resource and parse
-the high edge setting in the SMC91x driver, a use pattern
-that means every driver specifying an IRQ flag from a
-static resource need to parse resource flags and apply
-them at runtime.
-
-As we switched the code to use IRQ descriptors to retrieve
-the the trigger type like this:
-
- irqd_get_trigger_type(irq_get_irq_data(...));
-
-the code would work for new platforms using e.g. device
-tree as the backing irq descriptor would have its flags
-properly set, whereas this kind of oldstyle static
-resources at no point assign the trigger flags to the
-corresponding IRQ descriptor.
-
-To make the behaviour identical on modern device tree
-and legacy static platform data platforms, modify
-platform_get_irq() to assign the trigger flags to the
-irq descriptor when a client looks up an IRQ from static
-resources.
-
-Fixes: d52fdbb735c3 ("smc91x: retrieve IRQ and trigger flags in a modern way")
