I think that's pretty safe. Maybe some way to get feedback to/from cpu vendors about this would help. If we really want to kill highmem dead in 2.7, beating cpu vendors with a baseball bat until they^W^W^W^W^W^W^W^Wkindly asking cpu vendors to kill that fucking PAE shit dead (goddammit!) might help. -- wli
