Subject: [PATCH tip/core/rcu 0/2] rcu: fixes for RCU lockdep

Hello!

This set fixes a couple of problems with the RCU-based lockdep patches:

1.	Make the lockdep_rcu_dereference() message less alarmist

2.	Make rcu_read_lock_sched_held() take boot-time lack of
	preemption into account.

							Thanx, Paul
