Good question. There is nothing wrong with having the SPU call this,
i.e. it won't break stuff. The question is more if it should return
an SPU number instead of a CPU number. I've had people ask for
a feature like that in the past.

The node information returned from the call usually is the same for
the CPU and the SPU, but we don't guarantee that, unless the user
has specified node affinity.

I don't see a 'right' answer for your question, but I'd say let's
not forbid the user to call it and make it _SPU, even if it is
pointless.
