It looks like IA64 has introduced a start_pfn for xc_get_pfn_list().
The PPC port requires this as well since it allows us to fill in the
page_array a little bit at a time.
I can either replicate the IA64 ifdef logic (yuk!) or we can formally
add a start_pfn to this interface, since it _is_ a formal member of
the data structure.
I'll take a stab at it, if it is acceptable.
