- * This does simple reads from 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:
- *	user address in $2
- *	exception structure address in $3
- *	return address in $28 (exceptions expect it there)
- *
- * Output:
- *	error number in $0
- *	actual result in $1
- *
- * Clobbers:
- *	$4,$5
