Frederic Weisbecker 00f49e5729 rcu: Warn when rcu_read_lock() is used in extended quiescent state
We are currently able to detect uses of rcu_dereference_check() inside
extended quiescent states (such as the RCU-free window in idle).
But rcu_read_lock() and friends can be used without rcu_dereference(),
so that the earlier commit checking for use of rcu_dereference() and
friends while in RCU idle mode miss some error conditions.  This commit
therefore adds extended quiescent state checking to rcu_read_lock() and
friends.

Uses of RCU from within RCU-idle mode are totally ignored by
RCU, hence the importance of these checks.
