I would actually argue that they're scattered all over the place and it will
be hard to be sure that we have all the SWAPs we need and only the SWAPs we
need. Particularly to continue ensuring that given that most development
will be with minios having same endianness as Xen.

In short: it's ugly and unless someone really cares it will rot.
