[PATCH RFC tip/core/rcu 0/3] RT latency optimizations

[Paul E. McKenney]

Hello!

This series provides some minor latency optimizations for kernels that
build with CONFIG_RCU_NOCB_CPU_ALL=y:

1.	Create a static inline implementation of rcu_is_nocb_cpu() that
	unconditionally returns true when CONFIG_RCU_NOCB_CPU_ALL=y.

2.	Create a static inline implementation of rcu_needs_cpu() that
	unconditionally returns false when CONFIG_RCU_NOCB_CPU_ALL=y.

3.	Create static inline implementations of rcu_prepare_for_idle()
	and rcu_cleanup_after_idle() that are no-ops when
	CONFIG_RCU_NOCB_CPU_ALL=y.

							Thanx, Paul
