Merge tag 'perf-core-2021-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Thomas Gleixner:
"Core:
- Allow ftrace to instrument parts of the perf core code
- Add a new mem_hops field to perf_mem_data_src which allows to
represent intra-node/package or inter-node/off-package details to
prepare for next generation systems which have more hieararchy
within the node/pacakge level.
Tools:
- Update for the new mem_hops field in perf_mem_data_src
Arch:
- A set of constraints fixes for the Intel uncore PMU
- The usual set of small fixes and improvements for x86 and PPC"
