I tried this out under EFI and it dies horribly in the stub code because
we're missing at least one KASAN_SANITIZE_ Makefile entry.

So I think this needs longer to stew before hitting mainline. By all means
get the x86 dependencies in for 4.3, but the arm64 port can probably use
another cycle to iron out the bugs.

These series fixes boot crash with KASAN under EFI.
I'm sending it separetly for easier review.
We have one more small x86 dependcy in the first patch.
Patches 2-4 I'm going to squash into v6 'arm64: add KASAN support' patch.


Andrey Ryabinin (4):
  x86, efi, kasan: #undef memset/memcpy/memmove per arch.
  efi/runtime-wrappers, kasan: don't sanitize runtime wrappers.
  arm64/efi-stub, kasan: don't instrument efi-stub.
  libfdt, kasan: don't instrument libfdt.
