[PATCH tip/core/rcu 0/5] Documentation updates for 3.19

[Paul E. McKenney]

Hello!

This series contains a few documentation updates:

1.	Records limitations of bitfields and small variables.
	Also rules out pre-EV56 Alpha, which lack 8- and 16-bit
	memory-reference instructions.  Later Alpha CPUs are OK.
	(The official Alpha maintainers have thus far been silent
	on this patch.)

2.	Document the new RCU self-test boot parameters, courtesy of
	Pranith Kumar.

3.	Records that short-circuit boolean evaluation does not necessarily
	defend against control-dependency breakage by compiler optimizations.

4.	Add mention of atomic_long_t to atomic_ops.txt.

5.	Fix an example in memory-barriers.txt, courtesy of Pranith Kumar.

							Thanx, Paul
