Subject: [PATCH tip/core/rcu 04/12] rcu: Drive PROVE_RCU directly off of PROVE_LOCKING

From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>

In the past, it has been useful to enable PROVE_LOCKING without also
enabling PROVE_RCU.  However, experience with PROVE_RCU over the past
few years has demonstrated its usefulness, so this commit makes
PROVE_LOCKING directly imply PROVE_RCU.
