Subject: [PATCH tip/core/rcu 40/45] rcutorture: Run rcu_torture_writer at normal priority

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

There are usually lots of readers and only one writer, so if there has
to be a choice, we would want rcu_torture_writer to win.  This commit
therefore removes the set_user_nice() from rcu_torture_writer().
