[PATCH tip/core/rcu 0/12] TINY_RCU changes for 3.11

[Paul E. McKenney]

Hello!

This series removes TINY_PREEMPT_RCU, as promised/threatened at
http://lwn.net/Articles/541037/ and https://lkml.org/lkml/2012/11/12/545.

1.	Remove TINY_PREEMPT_RCU.  This is a straight syntactic removal,
	with no attempt at cleanup.  The remaining patches do the cleanup.

2.	Inline the now-empty show_tiny_preempt_stats() function.

3.	Inline the now-empty rcu_preempt_check_callbacks() function.

4.	Inline the now-empty rcu_preempt_remove_callbacks() function.

5.	Inline the now-empty rcu_preempt_process_callbacks() function.

6.	Because TINY_RCU no longer has kthreads, remove the code that
	used to abstract away kthread vs. softirq invocation.

7.	Inline the now-empty check_cpu_stall_preempt() function.

8.	Remove CONFIG_TINY_RCU ifdefs from include/linux/rcutiny.h

9.	Inline the now-empty rcu_preempt_note_context_switch() function.

10.	Move code to allow consolidating ifdefs in kernel/rcutiny_plugin.h.

11.	Remove TINY_PREEMPT_RCU's tracing formats from documentation.

12.	Shrink TINY_RCU a bit by moving exit_rcu() to TREE_RCU, leaving
	TINY_RCU with a static inline empty function.

							Thanx, Paul
