+Subject: [PATCH] Enable CET (-fcf-protection=full) by default
+
+Needs:
+- CET to be enabled for GCC
+- -DEXTRA_OPTIONS_CF to be passed during build (via toolchain.eclass)
+ for now to avoid accidentally enabling it on other arches.
+
+ Only supported on amd64.

11.3.0: fix CET patch
Our patch was causing unhandled state to leak into the LTO metadata writer,
it shouldn't have got that far though. Instead of messing about with GCC's
option handling, use the macro they provide for purposes like this, which
makes things far simpler (and less fragile).

+Subject: [PATCH] Fix target/103910: missing GTY on x86_mfence causing PCH
+ usage to ICE
+
+With -O3 -march=opteron, a mfence builtin is added after the loop
+to say the nontemporal stores are no longer needed. This all good
+without precompiled headers as the function decl that is referneced
+by x86_mfence is referenced in another variable but with precompiled
+headers, x86_mfence is all messed up and the decl was GC'ed away.
+This fixes the problem by marking x86_mfence as GTY to save/restore
+during precompiled headers just like most other variables in
+the header file.
+
+Committed as obvious after a bootstrap/test on x86_64-linux-gnu.

+Subject: [PATCH] libgo: don't include <linux/fs.h> when building
+ gen-sysinfo.go
+
+Removing this doesn't change anything at least with glibc 2.33.
+The include was added in https://go.dev/cl/6100049 but it's not
+clear why.
+
+Fixes PR go/106266
