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:
   - Clean up the x86 instruction decoder (Masami Hiramatsu)
   - Add new uprobes optimization for PUSH instructions on x86 (Yonghong
     Song)
   - Add MSR_IA32_THERM_STATUS to the MSR events (Stephane Eranian)
   - Fix misc bugs, update documentation, plus various cleanups (Jiri
     Olsa)
  There's a large number of tooling side improvements:
   - Intel-PT/BTS improvements (Adrian Hunter)
   - Numerous 'perf trace' improvements (Arnaldo Carvalho de Melo)
   - Introduce an errno code to string facility (Hendrik Brueckner)
   - Various build system improvements (Jiri Olsa)
   - Add support for CoreSight trace decoding by making the perf tools
     use the external openCSD (Mathieu Poirier, Tor Jeremiassen)
   - Add ARM Statistical Profiling Extensions (SPE) support (Kim
     Phillips)
   - libtraceevent updates (Steven Rostedt)
   - Intel vendor event JSON updates (Andi Kleen)
   - Introduce 'perf report --mmaps' and 'perf report --tasks' to show
     info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)
   - Add infrastructure to record first and last sample time to the
     perf.data file header, so that when processing all samples in a
     'perf record' session, such as when doing build-id processing, or
     when specifically requesting that that info be recorded, use that
     in 'perf report --time', that also got support for percent slices
     in addition to absolute ones.
     I.e. now it is possible to ask for the samples in the 10%-20% time
     slice of a perf.data file (Jin Yao)
   - Allow system wide 'perf stat --per-thread', sorting the result (Jin
     Yao)
     E.g.:
      [root@jouet ~]# perf stat --per-thread --metrics IPC
      ^C

   - Improve shell auto-completion of perf events (Jin Yao)
   - 'perf probe' improvements (Masami Hiramatsu)
   - Improve PMU infrastructure to support amp64's ThunderX2
     implementation defined core events (Ganapatrao Kulkarni)
   - Various annotation related improvements and fixes (Thomas Richter)
   - Clarify usage of 'overwrite' and 'backward' in the evlist/mmap
     code, removing the 'overwrite' parameter from several functions as
     it was always used it as 'false' (Wang Nan)
   - Fix/improve 'perf record' reverse recording support (Wang Nan)
   - Improve command line options documentation (Sihyeon Jang)
   - Optimize sample parsing for ordering events, where we don't need to
     parse all the PERF_SAMPLE_ bits, just the ones leading to the
     timestamp needed to reorder events (Jiri Olsa)
   - Generalize the annotation code to support other source information
     besides objdump/DWARF obtained ones, starting with python scripts,
     that will is slated to be merged soon (Jiri Olsa)
   - ... and a lot more that I failed to list, see the shortlog and
     changelog for details"
