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
               INTEL_PENTIUM3 686
               INTEL_CELERON3 686
               INTEL_PENTIUM4 686
AMD AMD_386 386
               AMD_486 486
               AMD_K5 586
               AMD_K6 K6
               AMD_K6II K6
               AMD_K6III K6
               AMD_K7 K7
               AMD_DURON K7
               AMD_ATHLON K7
CYRIX CYRIX_386 386
               CYRIX_486 486
               CYRIX_586 586
               CYRIX_686 686
VIA CYRIX_III 686
TRANSMETA TRANSMETA_CRUSOE ???
NATSEMI NATSEMI_586 586
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...
