From e6197acc726ab3baa60375a5891d58c2ee87e0f3 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Thu, 24 Feb 2011 14:20:12 -0500 Subject: xen/irq: Export 'xen_pirq_from_irq' function. We need this to find the real Xen PIRQ value for a device that requests an MSI or MSI-X. In the past we used 'xen_gsi_from_irq' since that function would return an Xen PIRQ or GSI depending on the provided IRQ. Now that we have seperated that we need to use the correct function.
