Current shadow code do prefetch in FNAME(prefetch_page), but it is only used to choose shadow_notrap_nonpresent_pte or shadow_trap_nonpresent_pte.
At least for L1 shadow, prefetching to get exact shadow L1 pte won't cause performance regression (though handling time increases slightly ) since it won't generate a new write protected page. for those L2+ shadow page tables, we can do similar for those pointed gfn which is already shadowed.
