Further cleanup of the hv drivers: 1) Cleanup the reference counting mess for both stor and net devices. 2) Handle all block devices using the storvsc driver. 3) Accomodate some host side scsi emulation bugs. 4) In case of scsi errors off-line the device. Regads, K. Y

Further cleanup of the hv drivers: 1) Continue to cleanup our drivers to conform to the Linux Driver Model. 2) Fix some long standing bugs with regards to unloading and reloading the drivers - block, net and stor. 3) VMBUS is an ACPI enumerated device; make VMBUS an ACPI bus driver. 4) Get rid of channel polling code; instead the channel receive paths will be purely interrupt

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
