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

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

If unsure, say N.
