CoreSight trace being updated to use the perf_report_aux_output_id() in a similar way to intel-pt.
This function in needs export visibility to allow it to be called from kernel loadable modules, which CoreSight may configured to be built as.

Are you happy with me picking up this change through the coresight tree ?
Suzuki
Please could you let me know your thoughts on this ? Coresight PMU would use this to inform the dynamically allocated trace id for a CPU to the perf via this HWID packet.
If you are happy with the above change, I could pick it up via the coresight tree with your Ack. Otherwise, please could you pick it up ?
