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:

  - Show precise number of samples in at the end of a 'record' session, if
    processing build ids, since we will then traverse the whole perf.data file
    and see all the PERF_RECORD_SAMPLE records, otherwise stop showing the
    previous off-base heuristicly counted number of "samples"  (Namhyung Kim).

  - Support to read compressed module from build-id cache (Namhyung Kim)

 Infrastructure changes:

  - Cache eh/debug frame offset for dwarf unwind (Namhyung Kim)

  - Set header version correctly in all cases (Namhyung Kim)

  - Set attr.task bit for a tracking event, to be consistent (Namhyung Kim)
    perf tools: Use perf_data_file__fd() consistently
    perf symbols: Convert lseek + read to pread

  - Don't rely on malloc working for sz 0, fixing another problem when
    using uClibc (Vineet Gupta)

  - Provide stub for missing pthread_attr_setaffinity_np for libcs where this
    is not available, such as uClibc (Vineet Gupta)
