- * This does simple writes to user mode, returning zero for
- * success and -EINVAL for a fault. Note that we may NOT do
- * unaligned accesses, because the unaligned fault handler
- * must not take the exception..
- *
- * NOTE! These are NOT normal function calls callable from C.
- * As we have two return values (the actual value gotten from
- * user space, and the error return value) the calling sequence
- * is different.
- *
- * Input:
- *	value to be written in $6
- *	user address in $7
- *	exception pointer in $8
- *	return address in $28 (exceptions expect it there)
- * Output:
- *	return value in $0
- * Clobbers:
- *	$1,$2,$3,$4,$5,$6
