Subject: [GIT PULL] Performance events updates for v5.12

Linus,

Please pull the latest perf/core git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2021-02-17

   # HEAD: 8bcfdd7cad3dffdd340f9a79098cbf331eb2cd53 Merge branch 'perf/kprobes' into perf/core, to pick up finished branch

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.

 Thanks,

	Ingo
