James, patch 1 fixes scanning of LUNs whose number is greater than 255. QEMU passes a max_lun of 16383 (because it uses SAM numbering) but in Linux it must become 32768 (because LUNs above 255 are "relocated" to 16640). Patch 2 is a resubmission of the patch for online resizing of virtio-scsi LUNs, which needs to be rebased. LUNs above 255 now work for all of scanning, hotplug,

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.
