mm: remember what the preferred zone is for zone_statistics
On NUMA, zone_statistics() is used to record events like numa hit, miss and foreign. It assumes that the first zone in a zonelist is the preferred zone. When multiple zonelists are replaced by one that is filtered, this is no longer the case. This patch records what the preferred zone is rather than assuming the first zone in the zonelist is it. This simplifies the reading of later patches in this set.
