I have added a hangup notifier that can be used by hvc console
backends to handle a tty hangup. The default irq hangup notifier
calls the notifier_del_irq() for compatibility.

to get "full-screen" terminal access to z/VM guest machines.
The solution consists of a HVC backend that provides the terminal interface;
