hi, following up on [1], this patchset factors out the MSR probe code and use it in msr,cstate* and rapl PMUs.
The functionality stays the same with one exception: the event is not exported if the rdmsr return zero on event's msr. I still need to run tests on other models and verify rapl model table properly, but I'd like to ask it something like this would be acceptable.
