Unfortunately refactoring the ia4 pagefault handler would require some refactoring in order to eliminate the 64k limitation, as far as I know, which doesn't seem to be feasible for this timeframe either. So if I personally have to chose from these two options, I'd prefer my patch for 2.6.32 and it'd be helpful if ia64 people could look into doing something with the 64k limit for 2.6.33. Acceptable for everyone? Ingo/Peter, will you merge this asap please, so that we don't miss 2.6.32 with it?
