Subject: [PATCH 04/12] xen: add missing definitions in include/xen/interface/vcpu.h which ia64/xen needs

Add xen handles realted definitions for xen vcpu which ia64/xen needs.
Pointer argumsnts for ia64/xen hypercall are passed in pseudo physical
address (guest physical address) so that it is required to convert
guest kernel virtual address into pseudo physical address.
The xen guest handle represents such arguments.
