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:

User visible changes:

  - Introduce 'srcfile' sort key: (Andi Kleen)

    # perf record -F 10000 usleep 1
    # perf report --stdio --dsos '[kernel.vmlinux]' -s srcfile
    <SNIP>
    # Overhead  Source File
        26.49%  copy_page_64.S
         5.49%  signal.c
         0.51%  msr.h
    #

    It can be combined with other fields, for instance, experiment with
    '-s srcfile,symbol'.

    There are some oddities in some distros and with some specific DSOs, being
    investigated, so your mileage may vary.

  - Update the column width for the "srcline" sort key (Arnaldo Carvalho de Melo)

  - Support per-event 'freq' term: (Namhyung Kim)

    $ perf record -e 'cpu/instructions,freq=1234/',cycles -c 1000 sleep 1
    $ perf evlist -F
    cpu/instructions,freq=1234/: sample_freq=1234
    cycles: sample_period=1000
    $

Infrastructure changes:

  - Move perf_counts struct and functions into separate object (Jiri Olsa)

  - Unset perf_event_attr::freq when period term is set (Jiri Olsa)

  - Move callchain option parsing code to util.c (Kan Liang)
