hm, OK, this seems to work:
--- a/include/linux/mmzone.h~a
+++ a/include/linux/mmzone.h
@@ -541,10 +541,13 @@ static inline int populated_zone(struct
return (!!zone->present_pages);

extern int movable_zone;
+#endif

(the first ifdef is just there to trip things at compile time rather than
link time)
