Subject: [PATCH] [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.
