Could this be organized this way ?

               IDT_WINCHIP3       ???      

Then for each model you would define its generic CONFIG_M<arch>, and
the specific features not contained in the generic. And then define
the rest of features based on generic.
The CONFIG_M<arch> would serve as a flag for 'this cpu has all features
of a generic xxx'.

Or if you are worried about namespace pollution these could be named
CONFIG_CPU_VENDOR_, CONFIG_CPU_, CONFIG_CPU_M.

BTW: any more stars in processor vendor/model sky ?

Comments awaited...
