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

The following changes since commit b3890e4704594fa23abe1395d1fafc97d3214be8:

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)
