Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
* 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 changes:
* 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)
