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

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

From: "Paul E. McKenney" <paulmck@linux.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.
