Doesn't 'logical_processors' (ignoring _available and _online) suffice
for your use case?

If not, and assuming you're on Apple hardware, I'm afraid there's no
way to ask OS X about hot swappable CPUs, because there is no such
concept in OS X. Also, I'm not aware of current Apple hardware that
supports hot-swapping CPUs.

If you run OS X on non-Apple hardware, maybe a device driver (kext)
could access such info.
