Following on from the previous work, this patchset gets tantalisingly close to bringing up a 64-bit Milax (OpenSolaris) kernel under qemu-system-sparc64:

Having said that, this is still a significant milestone :)

No further feedback, so I've applied this with the comment removed as per Zoltan's suggestion to git master.
