Re: patch to make /proc/cpuinfo show Indigo2

[Vince Weaver <weave@eng.umd.edu>]

Ugh, just realized that ./linux/arch/mips/arc/identify.c is used by more

Here is an updated patch, that should handle things correctly.

[P.S. (shameless plug)  If there is anoyone out there looking for a
 college student summer intern with some sgi/linux experience, let me
know]
