Subject: [PATCH] rcu: Add debug checks to TREE_PREEMPT_RCU for premature grace
 periods

Check to make sure that there are no blocked tasks for the previous
grace period while initializing for the next grace period, verify
that rcu_preempt_qs() is given the correct CPU number and is never
called for an offline CPU.
