Yeah, selftests is going to start suffering from the same "tools/ header
duplication" problem. I've also had cases (see the logic in the Makefile
in selftests/x86) where selftests is duplicating existing Kconfig and
Makefile logic ("can I build this way?")

But yes, I think getting a copy of asm.h would be nice here. I don't
think the WRITE_ONCE() is needed in this particular case. Hmm.
