rcu: Kick CPU halfway to RCU CPU stall warning When an RCU CPU stall warning occurs, the CPU invokes resched_cpu() on itself. This can help move the grace period forward in some situations, but it would be even better to do this -before- the RCU CPU stall warning. This commit therefore causes resched_cpu() to be called every five jiffies once the system is halfway to an RCU CPU stall warning. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
