I definitely agree, I don't think we want to go away from the page table as being the abstraction :-) But I'm wondering if we can do a little bit better with the accessors to those page tables.
BTW. am I the only one to have got one copy of David's reply (that I'm quoting) coming with a From: Nick Piggin in the headers ? (apparently coming from kvack).
