Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Ingo Molnar:
"Some tooling fixes plus three kernel fixes: a memory leak fix, a
statistics fix and a crash fix"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
perf/x86/intel/uncore: Fix memory leaks on allocation failures
perf/core: Fix cgroup time when scheduling descendants
perf/core: Avoid freeing static PMU contexts when PMU is unregistered
tools include uapi bpf.h: Sync kernel ABI header with tooling header
perf pmu: Unbreak perf record for arm/arm64 with events with explicit PMU
perf script: Add missing separator for "-F ip,brstack" (and brstackoff)
perf callchain: Compare dsos (as well) for CCKEY_FUNCTION
