Please edit this document to have consistent spacing. Its really hard to

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

You can enable this just fine on AMD machines.
The cache alloc code is under CPU_SUP_INTEL ..
