Subject: [GIT PULL] Performance events changes for v6.8


Linus,

Please pull the latest perf/core git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-core-2024-01-08

   # HEAD: fdd041028f2294228e10610b4fca6a1a83ac683d perf/x86/intel/uncore: Factor out topology_gidnid_map()

Performance events changes for v6.8 are:

 - Add branch stack counters ABI extension to better capture
   the growing amount of information the PMU exposes via
   branch stack sampling. There's matching tooling support.

 - Fix race when creating the nr_addr_filters sysfs file

 - Add Intel Sierra Forest and Grand Ridge intel/cstate
   PMU support.

 - Add Intel Granite Rapids, Sierra Forest and Grand Ridge
   uncore PMU support.

 - Misc cleanups & fixes.

 Thanks,

	Ingo
