Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf update from Thomas Gleixner: "The perf crowd presents: Kernel updates: - Removal of jprobes - Cleanup and consolidatation the handling of kprobes - Cleanup and consolidation of hardware breakpoints - The usual pile of fixes and updates to PMUs and event descriptors Tooling updates: - Updates and improvements all over the place. Nothing outstanding, just the (good) boring incremental grump work" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (103 commits) perf trace: Do not require --no-syscalls to suppress strace like output perf bpf: Include uapi/linux/bpf.h from the 'perf trace' script's bpf.h perf tools: Allow overriding MAX_NR_CPUS at compile time perf bpf: Show better message when failing to load an object perf list: Unify metric group description format with PMU event description perf vendor events arm64: Update ThunderX2 implementation defined pmu core events perf cs-etm: Generate branch sample for CS_ETM_TRACE_ON packet perf cs-etm: Generate branch sample when receiving a CS_ETM_TRACE_ON packet perf cs-etm: Support dummy address value for CS_ETM_TRACE_ON packet perf cs-etm: Fix start tracing packet handling perf build: Fix installation directory for eBPF perf c2c report: Fix crash for empty browser perf tests: Fix indexing when invoking subtests perf trace: Beautify the AF_INET & AF_INET6 'socket' syscall 'protocol' args perf trace beauty: Add beautifiers for 'socket''s 'protocol' arg perf trace beauty: Do not print NULL strarray entries perf beauty: Add a generator for IPPROTO_ socket's protocol constants tools include uapi: Grab a copy of linux/in.h perf tests: Fix complex event name parsing perf evlist: Fix error out while applying initial delay and LBR ...
