Subject: [PATCH tip/core/rcu 02/10] rcu: Make rcu_is_cpu_rrupt_from_idle helper functions static

From: Josh Triplett <josh@...htriplett.org>

Both rcutiny and rcutree define a helper function named
rcu_is_cpu_rrupt_from_idle(), each used exactly once, later in the
same file.  This commit therefore declares these helper functions static.
