SubjectRe: [RFC][PATCH v3] ftrace/x86_64: Emulate call function while updating in breakpoint handler
This looks sane to me, although I'm surprised that we didn't already
have an annotation for the nonstandard stack frame for asm files. That
probably would be cleaner in a separate commit, but I guess it doesn't
matter.

Anyway, I'm willing to consider the entry code version if it looks a
_lot_ simpler than this (so I'd like to see them side-by-side), but
it's not like this looks all that complicated to me either.
