Subject: [PATCH tip/core/rcu 0/13] Torture-test updates

Hello!

This series contains torture-test updates:

1.	Move SRCU status printing to SRCU implementations.

2.	Print SRCU lock/unlock totals because I am getting tired of
	doing the addition in my head.

3.	Remove CONFIG_TASKS_RCU ifdef from rcuperf.c.

4.	Select CONFIG_PROVE_LOCKING for Tiny SRCU scenario.

5.	Add --kconfig argument to kvm.sh to allow test runs to override
	the test-scenario files.

6.	Don't wait for kernel when all builds fail.

7.	Enable SRCU readers from timer handler.

8.	Place event-traced strings into trace buffer.

9.	Use nr_cpus rather than maxcpus to limit test size.

10.	Add task's CPU for rcutorture writer stalls.

11.	Eliminate unused ts_rem local from rcu_trace_clock_local().

12.	Add last-CPU to GP-kthread starvation messages.

13.	Invoke call_rcu() from timer handler.

							Thanx, Paul
