[PATCH v8 0/1] virtio_console: Add support for multiple console ports and generic serial ports

[Amit Shah <amit.shah@redhat.com>]

Hello all,

Here is a new iteration of the patch series that implements a
transport for guest and host communications.

I've tested for compatibility (old qemu & new kernel, new qemu & old
kernel, new qemu & new kernel) and it all works fine. To maintain
backward compatibility, the first port to be spawned (port at id 0) is
to be a console port, to be bound to hvc. This keeps new host, old
guest happy.

Christian has tested the console functionality on s390.

Please review and apply,
	Amit
