[GIT PULL rcu/urgent] rcu: Permit call_rcu() from CPU_DYING notifiers

[Paul E. McKenney]

Hello, Ingo,

The single commit in this pull request fixes a regression spotted
by Sergey Senozhatsky (https://lkml.org/lkml/2012/4/2/34).  The
underlying problem is that some CPU_DYING notifiers post RCU
callbacks from a CPU that has been marked offline.  The long-term
fix is to adopt those callbacks from RCU's CPU_DEAD notifier in
the 3.5 release.  For 3.4, this commit simply shuts off the warning.
(Yes, the warning will return in 3.5 also.)

This change is available in the git repository at:
  git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/urgent

							Thanx, Paul
