You're taking out the local_irq_enable() here but I don't see the
equivalent of adding it back in the 1/6 patch that moves the
cpuidle_idle_call() up to common code. It seems that one of the call
paths through cpuidle_idle_call() don't re-enable it on its own.
Even if this is the right thing to do, why it's OK to do so should
probably be documented in the patch description.
