Rusty, I have a mind to include this patchset for this merge window. Any input on this? This fixes the following virtio spec compliance issues: 1. on restore, drivers use device before setting ACKNOWLEDGE and DRIVER bits 2. on probe, drivers aren't prepared to handle config interrupts arriving before probe returns 3. on probe, drivers use device before DRIVER_OK it set Note that 1 is a

Changes from v4: rename virtio_enable_vqs_early() to virtio_device_ready() Note: Rusty requested we add a BUG_ON in the virtio_ring code. This can be done by a separate patch on top. Good for bisectability in case BUG_ON starts triggering :) Rusty, please review this, and consider for this merge window.
