Linux Kernel Configuration
└─>Support AMD processors
In linux kernel since version 2.6.28 (release Date: 2008-12-24)  
This enables detection, tunings and quirks for AMD processors

You need this enabled if you want your kernel to run on an
AMD CPU. Disabling this option on other types of CPUs
makes the kernel a tiny bit smaller. Disabling it on an AMD
CPU might render the kernel unbootable.

If unsure, say N.
