Merge tag 'perf-core-for-mingo' 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:
New user selectable features:
- Support recording running/enabled time in 'perf record' (Andi Kleen)
- New tool: 'perf data' for converting perf.data to other formats,
initially for the CTF (Common Trace Format) from LTTng (Jiri Olsa, Sebastian Siewior)
User visible changes:
- Only insert blank duration bracket when tracing syscalls in 'perf trace' (Arnaldo Carvalho de Melo)
- Filter out the trace pid when no threads are specified in 'perf trace' (Arnaldo Carvalho de Melo)
- Add 'perf trace' man page entry for --event (Arnaldo Carvalho de Melo)
- Dump stack on segfaults in 'perf trace' (Arnaldo Carvalho de Melo)
Infrastructure changes:
- Introduce set_filter_pid and set_filter_pids methods in the evlist class (Arnaldo Carvalho de Melo)
- Some perf_session untanglement patches, removing the need to pass a
perf_session instance for things that are related to evlists, so that
tools that don't deal with perf.data files like trace in live mode can
make use of the ordered_events class (Arnaldo Carvalho de Melo)
