[PATCH tip/core/rcu 0/2] Callback-offloading changes for 3.17

[Paul E. McKenney]

Hello!

This series provides a couple of callback-offloading changes:

1.	Parallelize and economize NOCB kthread wakeups to better handle
	cases where callback offloading is used on workloads that have
	many context switches and thus many grace periods.

2.	Don't offload callbacks for a given CPU unless it has been
	explicitly requested for that CPU, either directly at build
	time or boot time, or indirectly at boot time due to that
	CPU being a nohz_full CPU.

							Thanx, Paul
