Hello!

This series provides torture-test updates, and must be applied on top
of the SRCU series.

1.	Add testing for RCU's global memory ordering.

2.	Add debug output for wrong-CPU warning.

3.	Allow summarization of verbose output.

4.	Require entire stutter period be post-boot.

5.	Make synctype[] and nsynctype be static global.

6.	Make rcu_torture_fakewriter() use blocking wait primitives.

7.	Add fuzzed hrtimer-based sleep functions.

8.	Use torture_hrtimeout_jiffies() to avoid busy-waits.

9.	Make stutter use torture_hrtimeout_*() functions.

10.	Use hrtimers for reader and writer delays.

11.	Make refscale throttle high-rate printk()s.

12.	Throttle VERBOSE_TOROUT_*() output.

13.	Make object_debug also double call_rcu() heap object.

14.	Clean up after torture-test CPU hotplugging.

15.	Maintain torture-specific set of CPUs-online books.

16.	Break affinity of kthreads last running on outgoing CPU.

17.	Add rcutree.use_softirq=0 to RUDE01 and TASKS01.

						Thanx, Paul
