Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf tooling fixes from Thomas Gleixner:

 - Synchronization of tools and kernel headers

 - A series of fixes for perf report addressing various failures:
    * Handle invalid maps proper
    * Plug a memory leak
    * Handle frames and callchain order correctly

 - Fixes for handling inlines and children mode

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  tools/include: Sync kernel ABI headers with tooling headers
  perf tools: Put caller above callee in --children mode
  perf report: Do not drop last inlined frame
  perf report: Always honor callchain order for inlined nodes
  perf script: Add --inline option for debugging
  perf report: Fix off-by-one for non-activation frames
  perf report: Fix memory leak in addr2line when called by addr2inlines
  perf report: Don't crash on invalid maps in `-g srcline` mode
