Subject: [PATCH tip/core/rcu 0/3] SRCU changes for 3.20

Hello!

This series contains some minor changes to SRCU:

1.	Expand SRCU ->completed to 64 bits.  This is to be consistent with
	rcutorture, which now pays attention to this field for more precise
	error checking.

2.	Combine DEFINE_SRCU() and DEFINE_STATIC_SRCU().

3.	Make SRCU optional via a new CONFIG_SRCU Kconfig parameter,
	courtesy of Pranith Kumar.  This saves about 2KB.

								Thanx, Paul
