Subject: [PATCH tip/core/rcu 2/4] rcutorture: Make TREE03 use real-time tree.use_softirq setting

From: "Paul E. McKenney" <paulmck@...nel.org>

TREE03 tests RCU priority boosting, which is a real-time feature.
It would also be good if it tested something closer to what is
actually used by the real-time folks.  This commit therefore adds
tree.use_softirq=0 to the TREE03 kernel boot parameters in TREE03.boot.
