[PATCH] Fix zone policy determination
The use k in the inner loop means that the highest zone nr is always used if any zone of a node is populated. This means that the policy zone is not correctly determined on arches that do no use HIGHMEM like ia64. Change the loop to decrement k which also simplifies the BUG_ON.
