Commit f7b93d42945c ("arm64/alternatives: use subsections for replacement sequences") breaks LLVM's integrated assembler, because due to its one-pass design, it cannot compute instruction sequence lengths before the layout for the subsection has been finalized. This change fixes the build by moving the .org directives inside the subsection, so they are processed after the subsection layout is known.

Commit f7b93d42945c went in 5.8-rc4. Why is this cc stable from 4.14? If Will picks it up for 5.8, it doesn't even need a cc stable.
Greg or Sasha can probably answer why, but this patch is in 4.14.189, 4.19.134, 5.4.53, and 5.7.10, which ended up breaking some downstream Android kernel builds.
Please add a Fixes: tag as well.
Sure, I'll send v2 shortly with the tag. Thanks.
