Nick> It would be a big, annoying patch though :( We're currently working in a slightly different direction, to try to hide page-table implemention details from anything outside the page table implementation. Our goal is to be able to try out other page tables (e.g., Liedtke's guarded page table) instead of the 2/3/4 level fixed hierarchy. We're currently working on a 2.6.10 snapshot; obviously we'll have to roll up to 2.6.11 before releasing (and there are lots of changes there because of the recent 4-layer page table implementation). -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au The technical we do immediately, the political takes *forever* -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
