Every platform might not have userspace software that would do some
actions based on this. But, these are nice and useful stats to have.

They tell you a lot about how the hardware/governor/policies are
behaving with load. And so will eventually help getting performance based
on governor tunables for your platform. That's why I asked to put this in
core as this should be pretty much useful.
