Changed to;

+static inline struct free_area *
+fallback_buddy_reserve(int start_alloctype, struct zone *zone,
+                       unsigned int current_order, struct page *page,
+                       struct free_area *area)
+{
+       int reserve_type;
+       if (start_alloctype != RCLM_NORCLM)
+               return area;
+
+       area = &(zone->free_area_lists[RCLM_NORCLM][current_order]);
+
+       /* Reserve the whole block if this is a large split */
+       if (current_order >= MAX_ORDER / 2) {
+               reserve_type=RCLM_NORCLM;
