Also do you think you would be able to merge the driver (corresponding v4 patch follows) in the 3.2 merge window that seems to have just opened?

Aiming these for coming merge window. Nothing should change, but get ready for a non-guest-endian config transports, and > 32 features bits. Final one is just an overdue consolidation. Cheers, Rusty. Rusty Russell (7): virtio_config: introduce size-based accessors. virtio: use size-based config accessors. virtio_config: helpers for non-converting accessors. virtio_config: make
