Nice! I will add it on top, if you don?t mind (instead squashing it).
The original decision to have local/remote functions was mostly to provide
the generality.
I would change the last argument of __smp_call_function_many() from ?wait?
to ?flags? that would indicate whether to run the fun...

Nit: the compiler will probably inline this sucker anyway. So, for
these kinds of patches, I'd resist the urge to do these kinds of tweaks,
especially since it starts to hide the important change on the line.
