 Please send patches inline.

 Apart from the change to "arch/mips/kernel/cpu-probe.c", which is useful, 
what's the benefit of the changes?  Specifically how is selecting e.g. 
"CPU_4KSC" meant to be different from "CPU_MIPS32_R2"?  Do you want to 
make GCC tune your code according to a specific's CPU pipeline 
description?  If so, then it should probably be done a bit differently and 
there is actually no need to differentiate between specific members of the 
4K family.

 You should rather use your real name here.  [Hmm, why am I responding to 
an anonym in the first place?...]
