On the same note, is there any reason we want to expose
XEN_GUEST_HANDLE_PARAM to the guest?

It has been introduced with ARM to represent a guest pointer as an
hypercall pointer and only used within Xen to differentiate 32bit vs
64bit build.

XEN_GUEST_HANDLE will be different when built for 32-bit/64-bit as will
not really have any meaning from the guest POV.
