arm64 fix for 5.12-rc8/final

Hi Linus,

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.

Please pull the fix below for -rc8/final (Will's off today). Thanks.

The following changes since commit 738fa58ee1328481d1d7889e7c430b3401c571b9:
