I plan on posting a respin of it by next week, which should look pretty
much the same besides cleaning up the build error I introduced :)

Besides that, I think we need to decide on the KVM side of things
whether or not we want to support an event counter in addition to the
PMU cycle counter. Janne's FEX use case would certainly benefit from it.

Do you think you could grab patch #3? It is entirely unrelated to the
series at this point with the PMUv3 event remapping helper.
