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.
