[0/5] coresight: Fix snapshot mode

Message

Mathieu Poirier May 1, 2019, 5:50 p.m. UTC

This set fix miscellaneous problems that prevented perf's snapshot
mode from working properly when CoreSight events are used.

Given the late state in the cycle, it is sent out for reviewing
purposes and is not intended for the coming merge window.

Applies cleanly to coresight next[1].

Regards,
Mathieu
