Hi Carsten,

Because these apply to tools/perf files rather than the coresight drivers
they will need to apply to Arnaldo's perf/core branch. At the moment I'm
getting merge conflicts so I can't test and review them.

I also think you would have to do to: linux-perf-users@vger.kernel.org and acme@kernel.org
