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
