Subject: [PATCH tip/core/rcu 02/22] rcu: Four-level hierarchy is no longer experimental

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

Time to make the four-level-hierarchy setting less scary, so this
commit removes "Experimental" from the boot-time message.  Leave the
message in order to get a heads-up on any possible need to expand to
a five-level hierarchy.
