This patchset aims to integrate configuration and control of
the Coresight tracers with the perf sub-system.

The goal is to use PMUs to represent tracers and the auxiliary
buffer enhancement to collect processor traces.  As such a lot
of work is done to move the current Coresight sysFS oriented
configuration and control commands to perf's AUX API.

For the time being the work concentrates on ETMv3 and ETB1.0
sink buffers.  Work on ETMv4 and other type of sink buffers
will follow once a foundation has been established.

Also this patchset doesn't seem to apply to tip/perf/core, v4.3-rc3,
v4.2. What is it based on? Do you have a git branch with these patches
as well?
