I haven't attempted it on Loongson yet, but it'd be interesting to see
whether it works. You'd still have to emulate a Malta guest at the
moment. Getting it to work on the Ingenic XBurst cores required a little
effort in the kernel due to slight incompatibilities with the MIPS32r2
spec, so its possible there'll be problems with Loongson too.

I presume Loongson may use highmem, if so you'll want to disable it. I
still need to get those patches sorted out.

Let us know how it goes or if you hit problems!

Cheers
James
