Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull more perf updates from Ingo Molnar:
"A second (and last) round of late coming fixes and changes, almost all
of them in perf tooling:
User visible tooling changes:
- Add period data column and make it default in 'perf script' (Jiri
Olsa)
- Add a visual cue for toggle zeroing of samples in 'perf top'
(Taeung Song)
- Improve callchains when using libunwind (Namhyung Kim)
Tooling fixes and infrastructure changes:
- Fix for double free in 'perf stat' when using some specific invalid
command line combo (Yasser Shalabi)
- 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)
- Document sysfs events/ interfaces (Cody P Schafer)
- Fix typos in perf/Documentation (Masanari Iida)
- Add missing 'struct option' forward declaration (Arnaldo Carvalho
de Melo)
- Add option to copy events when queuing for sorting across cpu
buffers and enable it for 'perf kvm stat live', to avoid having
events left in the queue pointing to the ring buffer be rewritten
in high volume sessions. (Alexander Yarygin, improving work done
by David Ahern):
- 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)
- Move exit stuff from perf_evsel__delete to perf_evsel__exit, delete
should be just a front end for exit + free (Arnaldo Carvalho de
Melo)
- Add support to new style format of kernel PMU event. (Kan Liang)
and other misc fixes"
