Most of this patchset to implement the PMU has been merged already, but the interrupt-on-overflow behavior had some additional review comments. In addition to improving the overflow detection and bit-clearing logic, I split the previous patch [1] into two to (hopefully) make it more digestable.
There is also a separate bugfix for one of the the already-merged patches which I already sent out separately as "target/arm: Don't clear supported PMU events when initializing PMCEID1" [2].
