 * Internal access to HT Interface, general purpose features.

 * This file provides definitions used by HT internal modules.  The
 * external HT interface (in agesa.h) is accessed using these methods.
 * This keeps the HT Feature implementations abstracted from the HT
 * external interface.
 *
 * This file includes the interface support which is not removed with
 * various build options.
