Linus Torvalds d310ec03a3 The performance event updates for v5.12 are:
- Add CPU-PMU support for Intel Sapphire Rapids CPUs
 
  - Extend the perf ABI with PERF_SAMPLE_WEIGHT_STRUCT, to offer two-parameter
    sampling event feedback. Not used yet, but is intended for Golden Cove
    CPU-PMU, which can provide both the instruction latency and the cache
    latency information for memory profiling events.
 
  - Remove experimental, default-disabled perfmon-v4 counter_freezing support
    that could only be enabled via a boot option. The hardware is hopelessly
    broken, we'd like to make sure nobody starts relying on this, as it would
    only end in tears.
 
  - Fix energy/power events on Intel SPR platforms
 
  - Simplify the uprobes resume_execution() logic
 
  - Misc smaller fixes.
