 tagger Arnaldo Carvalho de Melo <acme@redhat.com> 1422562663 -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)
