I really hate we're duplicating all these things all over the place, but
I don't really know what to do about it either.

Anyway, it looks like perf_event_intel.c is missing 31, that said I
cannot seem to find model 31 on wikipedia either.

What about 44, WSM-EP ?

I understand NHM-EX (46) and WSM-EX (47) have different uncores not
implemented in this series, will those follow?
