Subject: [GIT PULL 00/16] perf/core improvements and fixes
Hi Ingo,
Please consider pulling, now to get back looking at eBPF :-)

perf probe: Support probing at absolute addresses (2015-08-25 12:36:22 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Add support for using several Intel PT features (CYC, MTC packets), the
relevant documentation was updated: tools/perf/Documentation/intel-pt.txt,
briefly describing those packets, its purposes, how to configure them in
the event config terms and relevant external documentation for further
reading. (Adrian Hunter)
- Introduce support for probing at an absolut address, for user and kernel
'perf probe's, useful when one have the symbol maps on a developer machine
but not on an embedded system (Wang Nan)
- Clear the progress bar at the end of a ordered_events flush, fixing
an UI artifact when, after ordering the events the screen doesn't get
completely redraw, for instance, when an error window covers just the
center of the screen and waits for user input. (Arnaldo Carvalho de Melo)
- Fix 'annotate' segfault by resetting the dso find_symbol cache when removing
symbols (Arnaldo Carvalho de Melo)
Infrastructure:
- Fix Intel PT 'instructions' sample period (Adrian Hunter)
- Prevent segfault when reading probe point with absolute address (Wang Nan)
Build fixes:
- Fix tarball build broken by pt/bts (Adrian Hunter)
