Subject: [PATCH v6 0/3] perf tools: Add support for some spe events

Hi Mark,

Yes I think this is something I can look into. For now I have removed
that last patch because the current patch set already works very similarly anyway
and allows people to use SPE in perf:

    ./perf record -e arm_spe_0/branch_filter=1/
vs
    ./perf record -e arm_spe/branch-misses/pp

Also I don't have access to any big.LITTLE hardware with SPE so wouldn't be able
to test collating all the SPE PMUs.

Thanks
James
