[GIT pull] perf fixes for 4.14

From: Thomas Gleixner
Date: Sun Nov 12 2017 - 06:48:59 EST


Linus,

please pull the latest perf-urgent-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus

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- Synchronize the i915 drm header to avoid the 'out of date' warning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


Thanks,

tglx
