TraceID values have to be unique for all tracers and
consistent between drivers and user space. As such
introducing a central function to be used whenever a
traceID value is required.
The patch also account for data traceIDs, which are usually
I(N) + 1.

coresight: etm-perf: new PMU driver for ETM tracers2016-02-20T22:11:01+00:00Mathieu Poiriermathieu.poirier@linaro.org2016-02-18T00:52:01+00:00urn:sha1:0bcbf2e30ff2271b54f54c8697a185f7d86ec6e4
Perf is a well known and used tool for performance monitoring
and much more. A such it is an ideal candidate for integration
with coresight based HW tracing.
This patch introduces a PMU that represent a coresight tracer to
the Perf core.
