[PATCH tip/core/rcu 0/6] Documentation updates for 3.21^W4.1

[Paul E. McKenney]

Hello!

This series contains a few documentation updates:

1.	Record the fact that the rcutree.kthread_prio kernel boot parameter
	also controls the priority of the grace-period kthreads.

2.	Update the kernel-per-CPU-kthreads.txt documentation based on
	Christoph Lameter's on-demand vmstat workers commit.

3.	Update NO_HZ.txt documentation to reflect the fact that POSIX
	timers are no longer starved on adaptive-ticks CPUs.

4.	Update kernel-per-CPU-kthreads.txt documentation to reflect
	workqueue usage and nosoftlockup boot parameter.

5.	Clarify memory-barrier semantics of atomic operations.

6.	Clarify control-dependency pairing.

							Thanx, Paul
