Merge branch 'core-locking-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking changes from Ingo Molnar:
"The most noticeable change are mutex speedups from Waiman Long, for
higher loads. These scalability changes should be most noticeable on
larger server systems.
There are also cleanups, fixes and debuggability improvements."
