[Qemu-devel] [PATCH] PPC: Initialize OpenPIC properly

[Alexander Graf]

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.
