I don't know if that's necessary ... it's obvious when looking at the
function:

static inline void *xa_mk_value(unsigned long v)
{
        WARN_ON((long)v < 0);
        return (void *)((v << 1) | 1);
}

and if you ignore it, you'll find out.  But if this needs to be
documented anywhere, it's in the kernel-doc for xa_mk_value()
and not in the maple tree docs.
