+Subject: [PATCH] libsanitizer: Remove cyclades inclusion in sanitizer
+
+The Linux kernel has removed the interface to cyclades from
+the latest kernel headers[1] due to them being orphaned for the
+past 13 years.
+
+libsanitizer uses this header when compiling against glibc, but
+glibcs itself doesn't seem to have any references to cyclades.
+
+Further more it seems that the driver is broken in the kernel and
+the firmware doesn't seem to be available anymore.
+
+As such since this is breaking the build of libsanitizer (and so the
+GCC bootstrap[2]) I propose to remove this.

+Subject: [PATCH] gcc/config.gcc: sh-*: Disable sysroot-suffix (PR42947)
+
+sh-* is a multilib target. It is also one of 2 sysroot-prefix targets.
+Unfortunately two options do not mix well. Attempt to use default
+multilib flavour always prepends sysroot-prefix.
