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   - synchronize the i915 drm header to avoid the 'out of date' warning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