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.
