As the alignment of 64bit platforms may be defferent from 32bit one,
should it be like the following?

static inline char *
iwe_stream_add_point(char *     stream,         /* Stream of events */
                     char *     ends,           /* End of stream */
                     struct iw_event *iwe,      /* Payload length + flags */
                     char *     extra,          /* More payload */
                     struct iw_request_info *info)
{
        int     event_len = IW_EV_POINT_LEN + iwe->u.data.length;
        int     point_len = IW_EV_POINT_LEN;
        int     lcp_len = IW_EV_LCP_LEN;

#ifdef CONFIG_COMPAT
        if (info->flags & IW_REQUEST_FLAG_COMPAT) {
                event_len = IW_EV_COMPAT_POINT_LEN + iwe->u.data.length;
                point_len = IW_EV_COMPAT_POINT_LEN;
                lcp_len = IW_EV_COMPAT_LCP_LEN;
        }
#endif

        /* Check if it's possible */
        if(likely((stream + event_len) < ends)) {
                iwe->len = event_len;
                memcpy(stream, (char *) iwe, IW_EV_LCP_PK_LEN);
                memcpy(stream + lcp_len,
                       ((char *) iwe) + IW_EV_LCP_LEN + IW_EV_POINT_OFF,
                       IW_EV_POINT_PK_LEN - IW_EV_LCP_PK_LEN);
                memcpy(stream + point_len, extra, iwe->u.data.length);
                stream += event_len;
        }
        return stream;
}

(Note that IW_EV_COMPAT_LCP_LEN is just a example; not defined anywhere)
