Hi Ingo,
Please consider pulling, I guess the changes are minor of affect just some
non-core feature, so it is you call if you prefer to pull it into perf/urgent instead.
Best Regards,

perf kvm stat live: Enable events copying (2014-10-15 17:39:03 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
* Add a visual cue for toggle zeroing of samples in 'perf top' (Taeung Song)
* Fix for double free in 'perf stat' when using some specific invalid
command line combo (Yasser Shalabi)
Infrastructure:
* Add option to copy events when queuing for sorting across cpu buffers
and enable it for 'perf kvm stat live', to avoid having events left
in the queue pointing to the ring buffer be rewritten in high volume
sessions. (Alexander Yarygin, improving work done by David Ahern):
* Document sysfs events/ interfaces (Cody P Schafer)
* Add support to new style format of kernel PMU event. (Kan Liang)
* Fix typos in perf/Documentation (Masanari Iida)
* Improve callchains when using libunwind (Namhyung Kim)

Listing specific events doesn't actually help us at all here because:
- these events actually vary between different ppc processors, they
aren't garunteed to be present.
- the documentation of the (generic) file contents is now superceded by the
docs for arbitrary event file contents.
