Ahh, I tried to look for that, but there was enough indirection and
confusion that I wasn't sure they were generically available.
And the "raw_cpu_*()" functions are rare enough that I'd never
encountered them enough to really be aware of them. In fact, we seem
to have exactly _one_ user of "raw_cpu_add()" in the whole kernel, and
a handful of "raw_cpu_inc()".
But ack on your patch, and a heartfelt "yeah, that's the right thing". Thanks,
Linus
