Hello!

This series contains performance improvements and locktorture testing
for percpu-rwsem:

1.	Add rtmutex torturing to locktorture, courtesy of Davidlohr Bueso.

2.	Add exports to allow locktorture to be built as a module.

3.	Add torture tests for percpu-rwsem.

4.	Consolidate cond_resched_rcu_qs() into stutter_wait().

5.	Create rcu_sync infrastructure, courtesy of Oleg Nesterov.

6.	Simplify rcu_sync using new rcu_sync_ops structure, courtesy
	of Oleg Nesterov.

7.	Add CONFIG_PROVE_RCU checks for rcu_sync, courtesy of Oleg Nesterov.

8.	Introduce rcu_sync_dtor(), courtesy of Oleg Nesterov.

9.	Make percpu_free_rwsem() after kzalloc() safe, courtesy of Oleg
	Nesterov.

10.	Make percpu-rwsem make use of rcu_sync, courtesy of Oleg Nesterov.

11.	Fix the comments outdated by rcu_sync, courtesy of Oleg Nesterov.

12.	Clean up the lockdep annotations in percpu_down_read(), courtesy
	Peter Zijlstra and of Oleg Nesterov.

13.	Cleanup the CONFIG_PROVE_RCU checks, courtesy of Oleg Nesterov.

							Thanx, Paul
