[GIT PULL] RCU changes for 2.6.35

[GIT PULL] RCU changes for 2.6.35

[Paul E. McKenney]

Hello, Ingo,

Here are the first installment of RCU changes for 2.6.35, this time
rebased to 2.6.34-rc7.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-2.6-rcu.git rcu/next

As noted earlier, Mathieu's debugobjects changes and Arnd's "sparse"
checks are also in the works.

							Thanx, Paul
