From: Avi Kivity on 10 Feb 2010 12:40 From: Alexander Graf <agraf(a)suse.de> We're using a switch table to find the irqprio that belongs to a specific interrupt vector. This table is part of the interrupt inject logic. Since we'll add a new function to stop interrupts, let's move this table out of the injection logic into a separate function.
