No. Please just remove the conditionals on the leaf pages. We know exactly what we require them to be, there is minimal cost and no downside to just setting the pte entries to what we want them to be for the identity mapping. It doesn't make sense for paravirtualization or anything else to influence that. This may be redoing work that has been done before but it is doing it all one common place. It does make sense not to overwrite the intermediate pages. Not overwriting intermediate pages is reasonable, and allows other things to be going on and to be preserved.
