Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Thomas Gleixner:
- plug a memory leak in the intel pmu init code
- clang fixes
- tooling fix to avoid including kernel headers
- a fix for jvmti to generate correct debug information for inlined
code
- replace backtick with a regular shell function
- fix the build in hardened environments
