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
