#     Pull arm64 fix from Catalin Marinas:
#      "Fix kernel compilation when using the LLVM integrated assembly.
#     
#       A recent commit (2decad92f473, "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"
#     
#     * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
