What do you want to solve, as yamt asked you first? He said pmap_extract() could be used to get PA from VA. You just answered pmap_extract() was bad API. What you were trying to solve? If existing API can solve it without bad side effect, I don't think it's so bad for your purpose and its design should be another discussion. --- Izumi Tsutsui
