rcu: Awaken grace-period kthread if too long since FQS
Recent kernels can fail to awaken the grace-period kthread for quiescent-state forcing. This commit is a crude hack that does a wakeup if a scheduling-clock interrupt sees that it has been too long since force-quiescent-state (FQS) processing. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
