Obviously, I've had no success as yet, so I'm stubbornly trying another approach! ;) This patch is just a small pre-patch to the real memory binding. It just adds get_zonelist() and get_node_zonelist() calls, to make some code a little more readable. This patch is super straight-forward. The real fun is in the next patch...
