Subject: [PATCH tip/core/rcu 0/3] Response-time changes for 3.15

Hello!

This series contains minor response-time improvements.

1.	Create trivial always-true version of rcu_is_nocb_cpu() for
	CONFIG_RCU_NOCB_CPU_ALL=y kernels.

2.	Create trivial always-false version of rcu_needs_cpu() for
	CONFIG_RCU_NOCB_CPU_ALL=y kernels.

3.	Don't bother doing CONFIG_RCU_FAST_NO_HZ work at idle entry
	and exit time for CONFIG_RCU_NOCB_CPU_ALL=y kernels.

							Thanx, Paul
