Subject: [PATCH] exports from rcu_idle_exit() and rcu_idle_enter()

References: bnc#978907 Scheduler performance -- idle
Patch-mainline: v4.14-rc1
Git-commit: 16c0b106070f4760f7d1fffb0cd40393552b5294

The rcu_idle_exit() and rcu_idle_enter() functions are exported because they
were originally used by RCU_NONIDLE(), which was intended to be usable from
modules.  However, RCU_NONIDLE() now instead uses rcu_irq_enter_irqson()
and rcu_irq_exit_irqson(), which are not exported, and there have been
no complaints.

This commit therefore removes the exports from rcu_idle_exit() and
rcu_idle_enter().
