Subject: [GIT PULL] perf updates/fixes
Linus,
Please pull the latest perf-urgent-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus
HEAD: 95cf59ea72331d0093010543b8951bb43f262cac perf: Fix perf_cgroup_switch for sw-events
This tree includes some late late perf items that missed the
first round:
tools:
* Bash auto completion improvements, now we can auto complete the tools long
options, tracepoint event names, etc, from Namhyung Kim.
* Look up thread using tid instead of pid in 'perf sched'.
* Move global variables into a perf_kvm struct, from David Ahern.
* Hists refactorings, preparatory for improved 'diff' command, from Jiri Olsa.
* Hists refactorings, preparatory for event group viewieng work, from Namhyung Kim.
* Remove double negation on optional feature macro definitions, from Namhyung Kim.
* Remove several cases of needless global variables, on most builtins.
* misc fixes
kernel:
* sysfs support for IBS on AMD CPUs, from Robert Richter.
* Support for an upcoming Intel CPU, the Xeon-Phi / Knights
Corner HPC blade PMU, from Vince Weaver.
* misc fixes
Thanks,
Ingo
