From d14ed2548c3163cdb316eb4da36cd7a6a8975da4 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 18 Dec 2009 23:37:26 +0100 Subject: target-ppc: Initialize OpenPIC properly When lowering an IRQ line, we search for the line we're supposed to lower. Usually we run into an optimization there that queues up interrupts. This queue ends with -1. Unfortunately we didn't set the first item to -1. This patch fixes this, making interrupts work on PPC64.
