Linus Torvalds 3871d93b82 Perf events updates for v6.1:
- PMU driver updates:
 
      - Add AMD Last Branch Record Extension Version 2 (LbrExtV2)
        feature support for Zen 4 processors.
 
      - Extend the perf ABI to provide branch speculation information,
        if available, and use this on CPUs that have it (eg. LbrExtV2).
 
      - Improve Intel PEBS TSC timestamp handling & integration.
 
      - Add Intel Raptor Lake S CPU support.
 
      - Add 'perf mem' and 'perf c2c' memory profiling support on
        AMD CPUs by utilizing IBS tagged load/store samples.
 
      - Clean up & optimize various x86 PMU details.
 
  - HW breakpoints:
 
      - Big rework to optimize the code for systems with hundreds of CPUs and
        thousands of breakpoints:
 
         - Replace the nr_bp_mutex global mutex with the bp_cpuinfo_sem
 	  per-CPU rwsem that is read-locked during most of the key operations.
 
 	- Improve the O(#cpus * #tasks) logic in toggle_bp_slot()
 	  and fetch_bp_busy_slots().
 
 	- Apply micro-optimizations & cleanups.
 
   - Misc cleanups & enhancements.
