I remember someone making noise about a need and don't remember the
context. I'll just let them take it up when the patches go out. I
actually presumed it wouldn't be natively supported, but rather be a
helper function for more general usage cases, esp. ones where > 1 cpu
is needed, but not all, and hitting every cpu on the system is greatly
more expensive than hitting only the desired cpus, which is about all
I remember of the noise that was made.
