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