#     Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
#     
#     Pull perf tooling updates from Ingo Molnar:
#      "Tooling changes only: fixes and a few stray improvements.
#     
#       Most of the diffstat is dominated by a PowerPC related fix of system
#       call trace output beautification that allows us to (again) use the
#       UAPI header version and sync up with the kernel's version of PowerPC
#       system call names in the arch/powerpc/kernel/syscalls/syscall.tbl
#       header"
#     
#     * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (36 commits)
