E.g. the hppa-linux-user port.  The initial merge ends at ebe9383caefd.

There are 15 patches -- mostly in linux-user -- before the one that enables
compilation.  At which point exactly zero instructions are actually implemented.

The actual cpu emulation comes afterwards in 8 patches (hppa 1.1 isn't terribly
complicated).
