4.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@linutronix.de>

commit 4364e1a29be16b2783c0bcbc263f61236af64281 upstream.

virq is not required to be the same for all msi descs. Use the base irq number
from the desc in the debug printk.
