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.

If the API allows us to query the tsc frequency, it would simply return the same values in all cases, which we'd ignore.
