i didn't intend to use this for stat.  that macro is a hook the common asm-
generic/statfs.h header provides for arches.

although maybe the better fix for statfs.h is to do:
--- a/include/uapi/asm-generic/statfs.h
+++ b/include/uapi/asm-generic/statfs.h
@@ -13,7 +13,7 @@

 #ifndef __statfs_word
 #if __BITS_PER_LONG == 64
-#define __statfs_word long
+#define __statfs_word __u64
 #else
 #define __statfs_word __u32
 #endif
