+ * __get_user_X
+ *
+ * Inputs:	r0 contains the address

+ * Outputs:	r0 is the error code
+ *		r2, r3 contains the zero-extended value
+ *		lr corrupted
+ *
+ * No other registers must be altered.  (see <asm/uaccess.h>
+ * for specific ASM register usage).

+ * Note that ADDR_LIMIT is either 0 or 0xc0000000.
+ * Note also that it is intended that __get_user_bad is not global.
