[PATCH 0/6] virtio: graceful failure with get == NULL
virtio 1.0 says device configuration is optional, but most drivers treat it as
mandatory. Even if presented by device, guest bios might disable the BAR
holding that configuration, so we can't assume it's there, but we also don't
want to fail if not in case drivers can cope with it's absence - such as caif
or rng.
Add code to drivers to check presence of get callback and fail

[PATCH v3 00/16] virtio-pci: towards virtio 1.0 guest support
Changes since v2:
handling for devices without config space (e.g. rng)
reduce # of mappings for VQs
These patches seem to work fine on my virtio-1.0 qemu branch.
There haven't been any bugs since v2: just minor cleanups
and enhancements.
QEMU side is still undergoing polishing, but is already testable.
Rusty, what do you think? Let's merge these for 3.20?
Also - will you be doing that
