Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf tool fixes from Thomas Gleixner:
"A small set of fixes for perf tool:
- synchronize the i915 drm header to avoid the 'out of date' warning
- make sure that perf trace cleans up its temporary files on exit
- unbreak the build with newer flex versions
- add missing braces in the eBPF parsing rules"
* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
tooling/headers: Sync the tools/include/uapi/drm/i915_drm.h UAPI header
perf trace: Call machine__exit() at exit
perf tools: Fix eBPF event specification parsing
perf tools: Add "reject" option for parse-events.l
