I think that's as simple as:

+++ b/mm/migrate.c
@@ -465,7 +465,7 @@ int migrate_page_move_mapping(struct address_space *mapping,
 
                for (i = 1; i < HPAGE_PMD_NR; i++) {
                        xas_next(&xas);
-                       xas_store(&xas, newpage + i);
+                       xas_store(&xas, newpage);
                }
        }
 

or do you see something else I missed?
