Adding a new file would seem too kludgy. Adding it to existing arch headers is
still OK but then one needs to know what exact syscall ABI each arch has as even
asm-generic ones differ depending on when the linux port was merged. And the only
way to know that is to do a build for each arch or is there some documentation one
could refer to.
