I have no problem keeping PG_reserved for that, and _ONLY_ for that.
(though i'd rather see it renamed then). I'm just afraid by doing so,
some drivers will jump in the gap and abuse it again...

Sure it would be renamed (better yet may be a slower page_is_valid()
that doesn't need to use a flag).

Right!  This is the correct time to wrap all remaining users (that use the 
newly-mandated valid page sense) in an inline or macro.  And this patch set 
should change the flag name, because it quietly changes the rules.  I think 
you need a 3/3 that drops the other shoe.
