[PATCH 0/4] arm_pmu: Add PERF_PMU_CAP_EXTENDED_HW_TYPE capability

[James Clark]

This came out of the discussion here [1]. It seems like we can get some
extra big.LITTLE stuff working pretty easily. The test issues mentioned
in the linked thread are actually fairly unrelated and I've fixed them
in a different set on the list.

After adding it in the first commit, the remaining ones tidy up a
related capability that doesn't do anything any more.

I've added a fixes tag for the commit where
PERF_PMU_CAP_EXTENDED_HW_TYPE was originally added because it probably
should have been added to the Arm PMU at the same time. It doesn't apply
cleanly that far back because another capability was added between then,
but the resolution is trivial.

Thanks
James
