I haven't looked at all at the details, but you can probably rephrase
this kind of "check address against range and pass recursively
to other bridge" algorithm in terms of appropriate statically
constructed memory regions. Since "transaction aborted" is
definitely not a fast path, the only argument for doing it that way
would be if the code worked out more neatly -- maybe worth
thinking about whether it would do so?
