The easiest thing is certainly to simply replace XEN_GUEST_HANDLE by
XEN_GUEST_HANDLE_64.

As to xlat.lst, just add ? entry there - the ? says the type needs to be
checked, and it is followed by the type's name and the header it is
found in. This will generate a CHECK_<typename> macro in
xen/include/compat/xlat.h, which you then ought to use somewhere in
the source code. Just pick one of the existing entries to see how this
works.
