From: Paul E. McKenney <paulmck@xxxxxxxxxx> commit 8d68e68a781db80606c8e8f3e4383be6974878fd upstream. The "NOHZ tick-stop error: Non-RCU local softirq work is pending" warning happens frequently and appears to be irrelevant to the various torture tests. This commit therefore filters it out. If there proves to be a need to pay attention to it a later commit will add an "advice" category to allow the user to immediately see that although something happened, it was not an indictment of the system being tortured.
