From db0f888848bc5cc578d005d04f4cf7a1105bb758 Mon Sep 17 00:00:00 2001 From: xiaoqiang zhao Date: Tue, 5 Nov 2013 18:16:05 +0800 Subject: ioapic: QOM'ify ioapic MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Convert 'init' function to QOM's 'realize' for ioapic and kvm-ioapic. Change variable 'ioapic_no' from static to global. Then we can drop the 'instance_no' function argument.
