Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking updates from Ingo Molnar:
"The main changes relate to making lock_is_held() et al (and external
wrappers of them) work on const data types - this requires const
propagation through the depths of lockdep.
This removes a number of ugly type hacks the external helpers used"
* 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
lockdep: Convert some users to const
lockdep: Make lockdep checking constant
lockdep: Assign lock keys on registration
