Cover letter Fwd: [RFC PATCH 00/15] ARM: perf: support multiple PMUs

The series is based on Will Deacon's perf-updates branch at:

       git://linux-arm.org/linux-2.6-wd.git perf-updates

An example driver using the framework (supporting the PMU present in L220/PL310 level 2 cache controllers) can be found at:

       git://linux-arm.org/linux-2.6-wd.git perf-l2x0-wip

Do you still maintain this tree? Looks it is empty. I'm wondering if we can make use of this to instrument the PMU counters of L2/pl310.

There's an old branch here, but this stuff is pretty bit-rotted and needs reworking as part of the big.LITTLE support:

Thanks, will look at it.
