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tool fixes from Thomas Gleixner: "A small set of fixes for perf tool: - synchronize the i915 drm header to avoid the 'out of date' warning - make sure that perf trace cleans up its temporary files on exit - unbreak the build with newer flex versions - add missing braces in the eBPF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
