3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <ben@decadent.org.uk>
commit 690cec8e70c211d1f5f6e520b21a68d0306173b6 upstream.
In uniprocessor configurations, synchronize_irq() is defined in <linux/hardirq.h> as a macro, and this function definition fails to compile.
