Subject: [PATCH tip/core/rcu 0/3] SRCU updates for 4.11

Hello!

This series provides updates to SRCU:

1.	This is a rewrite of the algorithm simplifying reader-count
	tracking.  Algorithm courtesy of Mathieu Desnoyers, implementation
	courtesy of Lance Roy.

2.	Force full grace-period ordering in SRCU.

3.	Add CBMC-based formal verification for SRCU, courtesy of Lance Roy.

							Thanx, Paul
