| * 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. |
| * Inputs: r0 contains the address |
| * Outputs: r0 is the error code |
| * r2, r3 contains the zero-extended value |
| * No other registers must be altered. (see include/asm-arm/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. |
