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

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf/x86/intel: Plug memory leak in intel_pmu_init()
  x86/asm: Allow again using asm.h when building for the 'bpf' clang target
  tools arch s390: Do not include header files from the kernel sources
  perf jvmti: Generate correct debug information for inlined code
  perf tools: Fix up build in hardened environments
