Subject: [PATCH tip/core/urgent] v2 rcu: updates for RCU lockdep

Hello!

These four patches provides a pair of new APIs and documentation to handle
a couple of cases that David Howells came across when running an NFS
workload under CONFIG_PROVE_RCU, along with some comment improvements
suggested by David and also some by Yong Zhang.

Updated from v1 (http://lkml.org/lkml/2010/4/9/28) to reflect David's
and Eric Dumazet's comments:

o	Remove (void*) cast from rcu_access_pointer().

o	Merge identical definitions of rcu_access_pointer() outside
	of #ifdef.

o	Merge comment syntax-error fix into comment patch.

							Thanx, Paul
