[PATCHv6 1/4] virtio: add names to virtqueue struct, mapping from devices to queues.
From: Rusty Russell <rusty at rustcorp.com.au>
Add a linked list of all virtqueues for a virtio device: this helps for
debugging and is also needed for upcoming interface change.
Also, add a "name" field for clearer debug messages.

[PATCH] virtio: support reserved vqs
virtio network device multiqueue support reserves
vq 3 for future use (useful both for future extensions and to make it
pretty - this way receive vqs have even and transmit - odd numbers).
Make it possible to skip initialization for
specific vq numbers by specifying NULL for name.
Document this usage as well as (existing) NULL callback.
Drivers using this not coded up yet, so I simply tested

This patch implements kvm guest kernel support for paravirtualized devices

o a basic virtio stub using virtio_ring and external interrupts and hypercalls
