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)
