Subject: Re: cpu masks on prtdiag

It's just the revision level of the photomasks
used to make the CPU die.
Other vendors call them steppings or revs.
Probably not useful for
much except for tracking down obscure bugs (they
don't make a new
version of the chip for the fun of it, each
revision fixes some bug or
performance issue, hopefully without introducing
new bugs).
