From a9552c8edbd31bf75d42b561f0a592c00aff1038 Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 5 Sep 2012 23:06:21 +0200 Subject: Introduce powerdown_notifiers Notifier will be used for signaling powerdown request to guest in a more general way and intended to replace very specific qemu_irq_rise(qemu_system_powerdown) and will allow to remove global variable qemu_system_powerdown.
