Subject: [GIT PULL] perf events changes for v6.7


Linus,

Please pull the latest perf/core git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2023-10-28

   # HEAD: 744940f1921c8feb90e3c4bcc1e153fdd6e10fe2 perf/x86/amd/uncore: Pass through error code for initialization failures, instead of -ENODEV

Performance events changes for v6.7 are:

 - Add AMD Unified Memory Controller (UMC) events introduced with Zen 4
 - Simplify & clean up the uncore management code
 - Fall back from RDPMC to RDMSR on certain uncore PMUs
 - Improve per-package and cstate event reading
 - Extend the Intel ref-cycles event to GP counters
 - Fix Intel MTL event constraints
 - Improve the Intel hybrid CPU handling code
 - Micro-optimize the RAPL code
 - Optimize perf_cgroup_switch()
 - Improve large AUX area error handling

 - Misc fixes and cleanups

 Thanks,

	Ingo
