I suppose you could say that. I think I saw someone post to this list

The mips64 tree in CVS is one that is a 64 bit addressing capable kernel.
AFAIK the linx convention is that <foo>64 refers to addressing (which
probably impiles register width too :>)
I'm not sure what the current state of the ELF64 MIPS toolchain is.
