Hi,
I'm reposting the whole series just in case my previous attempt to
repost only the broken patch was confusing. Patches are based on
4.5-rc2.
Patches 1-3 add support for ThunderX specific PMU events.
Patch 4 changes the cycle counter to overflow on 64 bit but tries to minimize
code changes. Without this change perf does not work at all on ThunderX.
Patch 5 extends the event mask according to ARMv8.1 and also affects arm32.
Changes to v2:
- fixed arm compile errors
Changes to v1:
- renamed thunderx dt pmu binding to thunder
