- * These functions have a non-standard call interface to make them more
- * efficient, especially as they return an error value in addition to
- * the "real" return value.
- *
- * __get_user_X
- *
- * Inputs: r0 contains the address
- * r1 contains the address limit, which must be preserved
- * Outputs: r0 is the error code
- * r2 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.
