[GIT PULL 00/14] perf/core improvements and fixes
From: Arnaldo Carvalho de Melo

Hi Ingo,
This comes with part of Adrian's latest pull req to support Intel PT
on tools/perf, with enough to testing it, see the example in the latest
patch in this series.
More wore patches for BTS and further Intel PT goodies will come soon,
after some issues with resolving symbols get fixed. This was something that
wasn't present last time I tested the BTS bits, so I think we should resolve
it soon, but while we do it, these patches should move things forward wrt
being able to test the stuff already in the kernel and to have access to this
hardware feature using perf.
Please consider applying,
- Arnaldo

perf tools: Take Intel PT into use (2015-08-17 11:11:37 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Support Intel PT in several tools, enabling the use of the processor trace
feature introduced in Intel Broadwell processors: (Adrian Hunter)
