- * Divide a 64-bit unsigned number by a 32-bit unsigned number.
- * This routine assumes that the top 32 bits of the dividend are
- * non-zero to start with.
- * On entry, r3 points to the dividend, which get overwritten with
- * the 64-bit quotient, and r4 contains the divisor.
- * On exit, r3 contains the remainder.
