Avi, i not understand it clearly, Could you please explain it? :-(
Right now if the fault is in spte i, you prefetch ptes
(i+1)..(i+MAX_PREFETCH-1). I'd like to prefetch ptes (i &
~(MAX_PREFETCH-1))..(i | (MAX_PREFETCH - 1)). Read all those gptes, and
map them one by one with speculative = false only for spte i.
Perhaps we need to integrate it into walk_addr, there's no reason to
read the gptes twice.
