Will fix all the spacing and other indentions issues mentioned. Thanks for pointing them all out. Although the other documents I see dont have a consistent format completely which is what confused me, this format would be better.

!x86 I think you mean, its entirely possible to have the code present

You can enable this just fine on AMD machines.

The cache alloc code is under CPU_SUP_INTEL ..

Thanks,
