Hmm, there might be even more cases of this. I remember pondering it when I did the original 4 level work (sometimes we discard higher level virtual address bits during walking) > (Note: We are in _urgent_ need to consolidate all those page table > walking functions, they all do things in a subtely different way, with > different checks (sometimes redudant) and inconsitent with each other, > even within a given set of them.

But it will just make them more similar, not completely consolidate them into an iterator, because that's too hard/ugly to do efficiently. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
