[PATCH v2 0/5] Cavium ThunderX uncore PMU support

This patch series provides access to various counters on the ThunderX SOC.

For details of the uncore implementation see patch #1.

Patches #2-5 add the various ThunderX specific PMUs.

As suggested I've put the files under drivers/perf/uncore. I would
prefer this location over drivers/bus because not all of the uncore
drivers are bus related.

Changes to v1:
- Added NUMA support
- Fixed CPU hotplug by pmu migration
- Moved files to drivers/perf/uncore
- Removed OCX FRC and LNE drivers, these will fit better into a edac driver
- improved comments abount overflow interrupts
- removed max device limit
- trimmed include files

Feedback welcome!
