Subject: [PATCH rcu 0/12] RCU-tasks torture-test updates

Hello!

This series contains torture-tests updates for the RCU tasks flavors,
most notably ensuring that building rcutorture and friends does not
change the RCU-tasks-related Kconfig options.

1.	Make TASKS_RUDE_RCU select IRQ_WORK.

2.	Make the TASKS_RCU Kconfig option be selected.

3.	Allow rcutorture without RCU Tasks Trace.

4.	Allow rcutorture without RCU Tasks.

5.	Allow rcutorture without RCU Tasks Rude.

6.	Add CONFIG_PREEMPT_DYNAMIC=n to TASKS02 scenario.

7.	Allow specifying per-scenario stat_interval.

8.	Allow refscale without RCU Tasks.

9.	Allow refscale without RCU Tasks Rude/Trace.

10.	Allow rcuscale without RCU Tasks.

11.	Allow rcuscale without RCU Tasks Rude/Trace.

12.	Adjust for TASKS_RCU Kconfig option being selected.

						Thanx, Paul
