Dual G3's in Umax S900?

[Cort Dougan]

Those are definitely not SMP chips.  The lack of the tlbie broadcast is a
killer.  I did some work with a dual 750 and implemented the software
broadcast in software (the code is still in the kernel - but unused) and it
was a nightmare of inefficiency.  In most benchmarks it turned out to be a
net negative to use the second processor.

Please... please, make the world a safer place for us on the verge of
insanity OS people and don't do a SMP 750!
