Yep, totally.

I thought about starting with mips64 but it was simpler to go with the
pre-existing processor support in the mips32 kernel. I'd like to patch
mips64 up to support the CPU's I have here, but not this month :>

Could someone quickly comment on how it is running? Can it boot normal 32
bit user space OK? I know with sparc64 there were (are?) a number of
problems with missing 32 bit syscall translations for some obscure
