It would be preferrable to have full 64 bit userspace for the other
ports as well. I know that on s390x, many users want to have more than
2GB virtual addressing space and 64 bit only userspace is usually faster
than mixed 32/64 bit space because you don't have to map all libraries
twice. We are definitely working towards a native s390x port,
probably other 64 bit ports aside from x86_64 and s390x are as well.
