Paul E. McKenney 778d250a29 rcu: Limit lazy-callback duration ...

Currently, a given CPU is permitted to remain in dyntick-idle mode
indefinitely if it has only lazy RCU callbacks queued.  This is vulnerable
to corner cases in NUMA systems, so limit the time to six seconds by
default.  (Currently controlled by a cpp macro.)
