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.

Please review !

Compared to v2 this series has:
 [1] Removed patch with raw-events support.
     It needs some rework and let's then discuss it separately.
     Still I plan to send it shortly.
 [2] Merged "set usable max period as a half of real max period" into
     "implement "event_set_period".
 [3] Fixed arc_pmu_event_set_period() in regard of incorrect
     "hwc->period_left" setup.
 [4] Moved interrupts enabling from arc_pmu_add() to arc_pmu_start()

Compared to v1 this series has:
 [1] Addressed review comments
 [2] More verbose commit messages and comments in sources
 [3] Minor cosmetics

Thanks,
Alexey
