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

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

Infrastructure fixes and changes:

  * Fix off-by-one bugs in map->end handling (Stephane Eranian)

  * Fix off-by-one bug in maps__find(), also related to map->end handling (Namhyung Kim)

  * Make struct symbol->end be the first addr after the symbol range, to make it
    match the convention used for struct map->end. (Arnaldo Carvalho de Melo)

  * Fix perf_evlist__add_pollfd() error handling in 'perf kvm stat live' (Jiri Olsa)

  * Fix python test build by moving callchain_param to an object linked into the
    python binding (Jiri Olsa)

  * Do not include a struct hists per perf_evsel, untangling the histogram code
    from perf_evsel, to pave the way for exporting a minimalistic
    tools/lib/api/perf/ library usable by tools/perf and initially by the rasd
    daemon being developed by Borislav Petkov, Robert Richter and Jean Pihet.
    (Arnaldo Carvalho de Melo)

  * Make perf_evlist__open(evlist, NULL, NULL), i.e. without cpu and thread
    maps mean syswide monitoring, reducing the boilerplate for tools that
    only want system wide mode. (Arnaldo Carvalho de Melo)
