This is the fourth revision of ARM performance counter support. This adds
support for software performance events on all ARM platforms and hardware
support for v6 processors. There is a generic PMU framework to allow for v7
and later to be added in the future.
Jamie Iles (5):
arm: provide a mechanism to reserve performance counters
arm/oprofile: reserve the PMU when starting
arm: use the spinlocked, generic atomic64 support
arm: enable support for software perf events
arm/perfevents: implement perf event support for ARMv6
