It increases the size of the cpuinfo_mips structure by sizeof(char *)
for data that is only ever used in /proc/cpuinfo, also it goes against
my sense of data normalization.  So I think the current method of
looking it up on demand is fine.

I am not enamored with my patch as it doubles the number of lines in
the function.  So we will defer to you and follow which ever style you
decide is best.
