Add nvcsw and nivcsw -- number of voluntary context switches and number of involuntary context switches to platforms supporting these. Roughly (and IIUC), voluntary context switches are when threads sleep or yield, involuntary are when threads are preempted.
I named these Voluntary and NonVoluntary context switches. I've seen both names used, not sure which is more common, but I think that is.
These are super useful for when working with performance and scheduler related things.
