Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
 "Kernel side changes:

   - x86 Intel uncore driver cleanups and enhancements (Kan Liang)

   - group scheduling and other fixes (Song Liu

   - store frame pointer in the sample traces for better profiling
     (Alexey Budankov)

   - compat fixes/enhancements (Eugene Syromiatnikov)

  Tooling side changes, which you can build and install in a single step
  via:

      make -C tools/perf clean install

  perf annotate:

   - Support 'perf annotate --group' for non-explicit recorded event
     "groups", showing multiple columns, one for each event, just like
     when dealing with explicit event groups (those enclosed with {})
     (Jin Yao)

   - Record min/max LBR cycles (>= Skylake) and add 'perf annotate' TUI
     hotkey to show it (c) (Jin Yao)

  perf bpf:

   - Add infrastructure to help in writing eBPF C programs to be used
     with '-e name.c' type events in tools such as 'record' and 'trace',
     with headers for common constructs and an examples directory that
     will get populated as we add more such helpers and the 'perf bpf'
     (Arnaldo Carvalho de Melo)

  perf stat:

   - Display time in precision based on std deviation (Jiri Olsa)

   - Add --table option to display time of each run (Jiri Olsa)

   - Display length strings of each run for --table option (Jiri Olsa)

  perf buildid-cache:

   - Add --list and --purge-all options (Ravi Bangoria)

  perf test:

   - Let 'perf test list' display subtests (Hendrik Brueckner)

  perf pti:

   - Create extra kernel maps to help in decoding samples in x86 PTI
     entry trampolines (Adrian Hunter)

   - Copy x86 PTI entry trampoline sections in the kcore copy used for
     annotation and intel_pt CPU traces decoding (Adrian Hunter)

  ... and a lot of other fixes, enhancements and cleanups I did not
  list, see the shortlog and git log for details"
