Merge tag 'perf-core-for-mingo-4.16-20180117' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

- Fix various per event 'max-stack' and 'call-graph=dwarf' issues,
  mostly in 'perf trace', allowing to use 'perf trace --call-graph' with
  'dwarf' and 'fp' to setup the callgraph details for the syscall events
  and make that apply to other events, whilhe allowing to override that on
  a per-event basis, using '-e sched:*switch/call-graph=dwarf/' for
  instance (Arnaldo Carvalho de Melo)

- Improve the --time percent support in record/report/script (Jin Yao)

- Fix copyfile_offset update of output offset (Jiri Olsa)

- Add python script to profile and resolve physical mem type (Kan Liang)

- Add ARM Statistical Profiling Extensions (SPE) support (Kim Phillips)

- Remove trailing semicolon in the evlist code (Luis de Bethencourt)

- Fix incorrect handling of type _TERM_DRV_CFG (Mathieu Poirier)

- Use asprintf when possible in libtraceevent (Federico Vaga)

- Fix bad force_token escape sequence in libtraceevent (Michael Sartain)

- Add UL suffix to MISSING_EVENTS in libtraceevent (Michael Sartain)

- value of unknown symbolic fields in libtraceevent (Jan Kiszka)

- libtraceevent updates: (Steven Rostedt)
  o Show value of flags that have not been parsed
  o Simplify pointer print logic and fix %pF
  o Handle new pointer processing of bprint strings
  o Show contents (in hex) of data of unrecognized type records
  o Fix get_field_str() for dynamic strings

- Add missing break in FALSE case of pevent_filter_clear_trivial() (Taeung Song)

- Fix failed memory allocation for get_cpuid_str (Thomas Richter)
