Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf events changes from Ingo Molnar:
"- kernel side:
- Intel uncore PMU support for Nehalem and Sandy Bridge CPUs, we
support both the events available via the MSR and via the PCI
access space.
- various uprobes cleanups and restructurings
- PMU driver quirks by microcode version and required x86 microcode
loader cleanups/robustization
- various tracing robustness updates
- static keys: remove obsolete static_branch()
- tooling side:
- GTK browser improvements
- perf report browser: support screenshots to file
- more automated tests
- perf kvm improvements
- perf bench refinements
- build environment improvements
- pipe mode improvements
- libtraceevent updates, we have now hopefully merged most bits with
the out of tree forked code base
... and many other goodies."
