Note that the 5Kc is one of the new generation of MIPS64 parts
that can enable 64-bit integer and floating point instructions without
requiring that 64-bit addressing also be enabled in the kernel.
Making Linux kernel support for this capability available is
one of the things that we're working on.  But it's not there yet.
