	ordering guarantees.

2.	Add verbiage stating that long-running irq handlers can stall
	RCU grace periods.

4.	Update description of RCU CPU stall warning messages.

5.	Replace uses of "transitive" in memory-barriers.txt.

6.	Rework multicopy-atomicity section of memory-barriers.txt,
	courtesy of Alan Stern.

7.	Fix RCU's docbook options.

8.	Add parameters to rcupdate.h docbook comments.

9.	Remove extra docbook comment in rculist.h.

10.	Fix docbook comments for rcu_sync functions.

11.	Fix list and emphasis in rcupdate.h docbook comments.

12.	Flag code segment in rcu_pointer_handoff()'s docbook comment.
