# commit d310ec03a34e92a77302edb804f7d68ee4f01ba0
# Merge: 657bd90c9314 8bcfdd7cad3d
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Sun Feb 21 12:49:32 2021 -0800

#     Merge tag 'perf-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull performance event updates from Ingo Molnar:
#     
#      - 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.
