[Xen-devel] [PATCH 07/10] xen: replace XEN_GUEST_HANDLE with XEN_GUEST_HANDLE_PARAM when appropriate



From: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>

Note: these changes don't make any difference on x86.

Replace XEN_GUEST_HANDLE with XEN_GUEST_HANDLE_PARAM when it is used as
an hypercall argument.

ijc v2: - correct usage of guest handle paramters in tmem
        - defer some changes to next patch to avoid temporarily
          breaking the build.
