Looks to me like all architectures are affected.  The change was made to 
struct rlimit in <linux/resource.h>:

-#define RLIM_INFINITY  ((long)(~0UL>>1))
+/*
+ * SuS says limits have to be unsigned.
+ *
+ * Which makes a ton more sense anyway.
+ */
+#define RLIM_INFINITY  (~0UL)
 
 struct rlimit {
-       long    rlim_cur;
-       long    rlim_max;
+       unsigned long   rlim_cur;
+       unsigned long   rlim_max;
 };
