Merge tag 'perf-core-2023-08-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf event updates from Ingo Molnar:
- AMD IBS improvements
- Intel PMU driver updates
- Extend core perf facilities & the ARM PMU driver to better handle ARM big.LITTLE events
- Micro-optimize software events and the ring-buffer code
- Misc cleanups & fixes
