[PATCH tip/core/rcu 0/7] Yet more RCU commits queued for 2.6.37

[Paul E. McKenney]

Hello!

This patchset shows additional patches queued for 2.6.37, over
and above those posted at http://lkml.org/lkml/2010/7/14/334 and
at http://lkml.org/lkml/2010/8/9/332.  These are all trivial fixes.
The patches are as follows:

1.	Allow kernel debuggers to avoid spurious RCU CPU stall warnings
	when restarting from a breakpoint via a new rcu_cpu_stall_reset().
2.	Repair code-duplication FIXMEs.  This code was temporarily
	duplicated to avoid inter-patch dependencies in the RCU tree.
3.	Document some additional ways of stalling updates to prevent
	call_rcu()-induced OOM situations.
4.	Update srcu_read_lock() docbook comment to note that it is
	illegal to wait for a given flavor of SRCU grace period while
	in that same flavor of SRCU read-side critical section.
5.	Combine duplicate code, courtesy of a newly refurbished
	CONFIG_PREEMPT_RCU symbol.  Also convert from macro to
	static inline function in a couple of places.
6.	Apply the TINY_PREEMPT_RCU read-side speedups/fixes to
	TREE_PREEMPT_RCU.  This update to TINY_PREEMPT_RCU update was
	posted at http://lkml.org/lkml/2010/8/17/437.
7.	Add a comment stating that list_empty() serves the function of
	the non-existent list_empty_rcu().
