This patch set if my first attempt to make virtio_console usable on s390. To do so, I had to change hvc_console, because s390 has no request_irq and no free_irq. I want to get feedback from the main users of hvc_console before I proceed. The basic idea of this patch set is to remove the calls to request_irq and free_irq and replace them with backend specific callbacks. Please see the
