Address Greg's VmBus audit comments: 1) Leverage driver_data field in struct hv_vmbus_device_id to simplify driver code. 2) Make the util driver conform to the Linux Driver Model. 3) Get rid of the ext field in struct hv_device by using the driver specific data functionality. 4) Other general cleanup. Regards, K. Y

The main motivation for this patch is to enable cloud service providers to provide an accelerated datapath to virtio-net enabled VMs in a transparent manner with no/minimal guest userspace changes. This also enables hypervisor controlled live migration to be supported with VMs that have direct attached SR-IOV VF devices. Patch 1 introduces a failover module that provides a generic interface for
