Pull arm64 fix from Catalin Marinas:
 "Fix kernel compilation when using the LLVM integrated assembly.

  A recent commit (3c9652edccf6, "arm64: mte: Ensure TIF_MTE_ASYNC_FAULT
  is set atomically") broke the kernel build when using the LLVM
  integrated assembly (only noticeable with clang-12 as MTE is not
  supported by earlier versions and the code in question not compiled).
  The Fixes: tag in the commit refers to the original patch introducing
  subsections for the alternative code sequences"
