Could this be organized this way ?

CONFIG_VENDOR_ CONFIG_CPU_ CONFIG_M

GENERIC GENERIC_386 386
GENERIC_486 486
GENERIC_586 586
GENERIC_686 686
INTEL INTEL_386 386
INTEL_486 486
INTEL_PENTIUM 586
INTEL_PENTIUMMMX 586
INTEL_PENTIUMPRO 686
INTEL_PENTIUM2 686
INTEL_CELERON2 686

TRANSMETA TRANSMETA_CRUSOE ???

RISE RISE_586 586
IDT IDT_WINCHIPC6 ???
IDT_WINCHIP2 ???
IDT_WINCHIP2A ???
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...
