[Arnaldo Carvalho de Melo]

Hi Ingo,

	Please consider pulling, there is some more stuff in queue to be
processed, but better send in smaller batches,

  perf symbols: Convert lseek + read to pread (2015-01-29 17:02:01 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- 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:

- 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)
