Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar: "The main kernel changes were: - add support for Intel's "adaptive PEBS v4" - which embedds LBS data in PEBS records and can thus batch up and reduce the IRQ (NMI) rate significantly - reducing overhead and making call-graph profiling less intrusive. - add Intel CPU core and uncore support updates for Tremont, Icelake, - extend the x86 PMU constraints scheduler with 'constraint ranges' to better support Icelake hw constraints, - make x86 call-chain support work better with CONFIG_FRAME_POINTER=y - misc other changes Tooling changes: - updates to the main tools: 'perf record', 'perf trace', 'perf stat' - updated Intel and S/390 vendor events - libtraceevent updates - misc other updates and fixes" * 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (69 commits) perf/x86: Make perf callchains work without CONFIG_FRAME_POINTER watchdog: Fix typo in comment perf/x86/intel: Add Tremont core PMU support perf/x86/intel/uncore: Add Intel Icelake uncore support perf/x86/msr: Add Icelake support perf/x86/intel/rapl: Add Icelake support perf/x86/intel/cstate: Add Icelake support perf/x86/intel: Add Icelake support perf/x86: Support constraint ranges perf/x86/lbr: Avoid reading the LBRs when adaptive PEBS handles them perf/x86/intel: Support adaptive PEBS v4 perf/x86/intel/ds: Extract code of event update in short period perf/x86/intel: Extract memory code PEBS parser for reuse perf/x86: Support outputting XMM registers perf/x86/intel: Force resched when TFA sysctl is modified perf/core: Add perf_pmu_resched() as global function perf/headers: Fix stale comment for struct perf_addr_filter perf/core: Make perf_swevent_init_cpu() static perf/x86: Add sanity checks to x86_schedule_events() perf/x86: Optimize x86_schedule_events() ...
