I understand the feeling.

I'm one of those who suggested (but not required) to put full-asm
function in .S files for a reason; I personally think the reboot code
may remain as it is, given the effort involved.  There are minor
details that may be better, but since I'm unable to suggest (and at
least compile-test) them for lack of time, I'm not even listing them.

Thank you very much for your efforts in following previous
suggestions.
