This defines on_one_cpu() which is similar to smp_call_function_single()
except that it works if cpu happens to be the current cpu. Can also be
seen as a complement to on_each_cpu() (which also doesn't treat the
current cpu specially).

Would you mind renaming that one to simply 'on_cpu'? It's even shorter and
clearly everybody will know what its purpose is. Also I doubt we will ever
have something like 'on_two_cpus'.
