Merge branch 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next
Pull core locking updates from Ingo Molnar:
"The main changes in this cycle were:
- reduced/streamlined smp_mb__*() interface that allows more usecases
and makes the existing ones less buggy, especially in rarer
architectures
- add rwsem implementation comments
- bump up lockdep limits"
* 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (33 commits)
rwsem: Add comments to explain the meaning of the rwsem's count field
lockdep: Increase static allocations
