Looks good.

Is anything preventing us from unifying the constant_tsc and !same paths? We could just do a quick check in the notifier, see the tsc frequency hasn't changed, and return.

Actually, yes. On constant_tsc processors, the processor frequency may still change, however the TSC frequency does not change with it.

I actually have both of these kinds of processors (freq changes with constant TSC and freq changes with variable TSC) so I was able to test both of these cases.
