Merge tag 'perf-core-for-mingo-4.18-20180502' of... 

Merge tag 'perf-core-for-mingo-4.18-20180502' 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:

perf stat: (Jiri Olsa)

- Display time in precision based on std deviation

- Add --table option to display time of each run

- Display length strings of each run for --table option

perf buildid-cache: (Ravi Bangoria)

- Add --list and --purge-all options

perf test: (Hendrik Brueckner)

- Let 'perf test list' display subtests

Core libraries:

- Remove the splitting of maps into MAP__FUNCTION and MAP__VARIABLE.
  It isn't needed, adds complexity, so remove this split in a very granular
  fashion using better ways of detecting if a map is executable, using map->prot,
  etc. More is needed to further untangle map aspects from DSO ones and
  also to have arch specific stuff better isolated.  (Arnaldo Carvalho de Melo)

- Fix spelling mistake: "builid" -> "buildid" in a jitdump error
  message (Colin Ian King)

Build system: (Jiri Olsa)

- Add support to check 2 independent files in check-headers.sh

Documentation: (Takashi Iwai)

- Support for asciidoctor, since 'asciidoc' wasn't so far ported to
  python3 and distros are ditching python2
