After removing a monitor group, its RMID may not be freed immediately
unless its llc_occupancy is less than the re-allocation threshold. If
turning up the threshold, the RMID can be reused. In order to know how
much the threshold should be, it's necessary to acquire the llc_occupancy.

The patch series provides a new tracepoint to track the llc_occupancy.

Changes since v1:
- Rename pseudo_lock_event.h instead of creating a new header file.
- Modify names used in the new tracepoint
- Update changelog

  x86/resctrl: Rename pseudo_lock_event.h to trace.h

Hi Haifeng,

Typo in subject:  llc_occpuancy ->  llc_occupancy
Could you also please use the x86/resctrl subject prefix in the cover letter?

Thank you

Reinette
