Subject: [GIT PULL rcu/urgent] Prevent RCU callbacks from executing during
 early boot

Hello, Ingo,

This pull request fixes a rare but real boot-time hang.  It defers RCU
callback execution until the scheduler has initialized, permitting
RCU callbacks that use late-initialized kernel features to be used in
RCU callbacks that are registered during early boot.  This fixes the
bugzilla at: https://bugzilla.kernel.org/show_bug.cgi?id=38732

This commit is available in the git repository at:

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

							Thanx, Paul
