Isn't the qemu_irq passed as the third argument to the callback? I
thought this solution was fine because you weren't passing the "int n"
from sysbus_connect_irq to your notifier.
If you really cannot make it work, I guess your "sysbus: add
irq_routing_notifier" patch would be okay. I would only ask you to move
the function pointer from SysBusDevice to SysBusDeviceClass.
Thanks,
