I couldn't find a kernel Documentation link handy. But, I found this
email from Boris:
https://lore.kernel.org/lkml/20190411135547.GH30080@zn.tnic/

I believe at least arch/x86 follows this for the most part. One simple
reason is to make it easier to find headers when a ton of them are
included in the same file.
