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" * tag 'perf-core-2021-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/intel: Fix ICL/SPR INST_RETIRED.PREC_DIST encodings powerpc/perf: Fix data source encodings for L2.1 and L3.1 accesses tools/perf: Add mem_hops field in perf_mem_data_src structure perf: Add mem_hops field in perf_mem_data_src structure perf: Add comment about current state of PERF_MEM_LVL_* namespace and remove an extra line perf/core: Allow ftrace for functions in kernel/event/core.c perf/x86: Add new event for AUX output counter index perf/x86: Add compiler barrier after updating BTS perf/x86/intel/uncore: Fix Intel SPR M3UPI event constraints perf/x86/intel/uncore: Fix Intel SPR M2PCIE event constraints perf/x86/intel/uncore: Fix Intel SPR IIO event constraints perf/x86/intel/uncore: Fix Intel SPR CHA event constraints perf/x86/intel/uncore: Fix Intel ICX IIO event constraints perf/x86/intel/uncore: Fix invalid unit check perf/x86/intel/uncore: Support extra IMC channel on Ice Lake server
