For an ioctl, please follow the normal pattern of defining a separate

You can use a void __user * in the common ioctl function, and pass that
to the typed argument list in the specific functions.

I have a GPL question.  This header file is currently licensed under the  GPL v2
only.  Does that mean that any application that includes this header file so
that it can talk to the driver/hypervisor also needs to be licensed under the GPL?
