One of these days I'm going to enable softmmu for linux-user, at least as an
option.  While direct loads and stores are nice, there are a whole pile of
things that Just Don't Work.

Especially guests with page sizes smaller than the host.  Very few of the
linux-user-test-0.3 suite even load e.g. on ppc64/aarch64 with a 64k page size.
