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 buffer. Work on ETMv4 and other type of sink buffers will follow once a foundation has been established.

Changes since V1: * Fixed typos in typographical error in documentation. * Moved to a multi session support scheme. * Split static and dynamic tracer configuration. * Fixed configuration for user and kernel space tracing. * Using WARN_ON_ONCE() rather than WARN_ON(). * Implemented strategy to prevent tracers from being used simultaneously. * Changed sink_ops::unset_buffer() to sink_ops::reset_buffer(). * Moves ETM's sysFS interface from driver core to dedicated file. * Removed spinlock in "etm_cpu_id()". * Aggregated PMU driver pieces in a single patch. * Added user space changes and rebased everything to v4.3-rc5.
