[PATCH tip/core/rcu 0/6] Documentation changes for 3.15

[Paul E. McKenney]

Hello!

This series provides a variety of documentation updates:

1.	Update the documentation on actions to take to avoid frenetic
	call_rcu() invocations from exhausting memory, including a mention
	of internal-to-RCU avoidance measures.

2.	Add a note to Documentation/memory-barriers.txt stating that
	ACCESS_ONCE() provides cache coherence for accesses to any
	single given variable.

3.	Add an explicit statement that in control dependencies, the
	condition must include the load in question.

4.	Add WQ_SYSFS workqueues as a work-offloading option in
	Documentation/kernel-per-CPU-kthreads.txt.

5.	It turns out that some types of control dependencies require
	memory barriers, most notably when the exact same store is
	at the beginning of both the then-clause and the else-clause.
	Document this.

6.	Fixups to RTFP.txt

							Thanx, Paul
