ifa->ifa_address and ifa->ifa_mask are defined as __u32, but used as if they were char[4]. Network code uses htons() to convert it. So UML's method to access these fields is wrong for bigendians (e.g. s390) I replaced bytewise copying by memcpy(), maybe even that might be removed, if ifa->ifa_address/mask may be used immediately.
