I'm getting a pile of build errors from this patchset (and related
patches).  Due to messed up merge fixing, probably.  Please the review
process has been a bit bumpy.

So I'll drop

kasan-allow-kasan_check_read-write-to-accept-pointers-to-volatiles.patch
asm-generic-x86-wrap-atomic-operations.patch
asm-generic-x86-wrap-atomic-operations-fix.patch
asm-generic-add-kasan-instrumentation-to-atomic-operations.patch
asm-generic-fix-compilation-failure-in-cmpxchg_double.patch
x86-remove-unused-atomic_inc_short.patch
x86-asm-generic-add-kasan-instrumentation-to-bitops.patch

for now.  Please resend (against -mm or linux-next) when the dust has
settled.
