early_cpu_init

[Joilnen Leite]

Hi 

in the function:
early_cpu_init we could to change to avoid initialize
unecessary code ?

arch/i386/cpu/common.c:536
void __init early_cpu_init(void)
{
#ifdef CONFIG_MCYRIXIII         
         cyrix_init_cpu();
#elif defined CONFIG_MGODE6X1
         nsc_init_cpu();
#elif defined CONFIG_MK6 || defined CONFIG_MK7
||defined CONFIG_MK8
         amd_init_cpu();
#elif defined CONFIG_CRUSOE || defined CONFIG_EFFICEON
         transmeta_init_cpu();
#elif defined OTHERS_THAT_I_DONT_KNOW
         centaur_init_cpu();
         rise_init_cpu();
         nexgen_init_cpu();
         umc_init_cpu();
         early_cpu_detect();
#else
         intel_cpu_init();

just only a idea.

thanks Joilnen

AFAIK, it's done without the ifdefs so that a common kernel (like a
distro kernel) can run on any of those CPU types.
