Hi Peter, This mini-series adds perf support for ARCv2 based cores, which brings in overflow interupts and SMP. Additionally now raw events are supported as well.
This is part of series which adds ARCv2 ISA support to linux. Please see [1] for prep patches and [2] for actual port. I've CC'ed you for some of the patches related to barriers, atomic ops in [2].
