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

Pull perf fixes from Thomas Gleixner:
 "A series of fixes for perf tooling:

   - Make xyarray return the X/Y size correctly which fixes a crash in
     the exit code.

   - Fix the libc path in test so it works not only on Debian/Ubuntu
     correctly

   - Check for eBPF file existance and output a useful error message
     instead of failing to compile a non existant file

   - Make sure perf_hpp_fmt is not longer references before freeing it

   - Use list_del_init() in the histogram code to prevent a crash when
     the already deleted element is deleted again

   - Remove the leftovers of the removed '-l' option

   - Add reviewer entries to the MAINTAINERS file"
