Oops, here they are:

Standard kernel (original config: make allnoconfig + CONFIG_EMBEDDED):
> size vmlinux
   text    data     bss     dec     hex filename
 966473  139000   90112 1195585  123e41 vmlinux

Size of vmlinux: 1386005

With the patch (using only CONFIG_CPU_SUP_INTEL):
> size vmlinux
   text    data     bss     dec     hex filename
 957561  136536   90112 1184209  1211d1 vmlinux
(-9812) (-2464)

Size of vmlinux: 1373697 (-12308 bytes)

-12K in the kernel size looks quite nice to me.

Michael.
