From 583617b7866cfcc0b3830a4b7ab20f218d180f67 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Mon, 21 Dec 2009 20:21:23 +0100 Subject: KVM: powerpc: Move vector to irqprio resolving to separate function 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.
