I've researched this.  It is harmless.  I'm adding code to the base MIPS
code to handle this.  (REVISION 2.50 of the MIPS Privileged Resource
Architecture defines REVISION 2.  It has some small changes, but I don't
think any of them are terribly relevant to us.)

Interestingly enough, I believe this processor supports the MIPS16e
ISA.  It maybe interesting to add support for this ISA to the port, as
it could result in a lot of savings in the code size -- cutting ~40% off
the code size would be very useful for some of these embedded systems
with only a few megabytes of flash.
