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- synchronize the i915 drm header to avoid the 'out of date' warning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"
