See include/asm-generic/Kbuild:
mandatory-y += bug.h
...
mandatory-y += rwonce.h

IOW, sh will have asm/bug.h and as/rwonce.h copied from asm-generic.

Still, includes of asm/*.h had been a massive headache historically
and breeding more of those shouldn't be overdone.

More painful problem is arch- and config-dependent stuff, though...
