Series perf/core: Add ability for an event to "pause" or "resume" AUX area tracing |

Commit Message

Adrian Hunter Feb. 8, 2024, 11:31 a.m. UTC 
  Set pmu->auxtrace on ARM/ARM64 AUX area PMUs. evsel__is_aux_event() needs
the setting to identify AUX area tracing selected events.

Currently, the features that use evsel__is_aux_event() are used only by
Intel PT, but that may change in the future.
