/* ChangeLog:
 *
 * Wed Mar 31 17:35:01 CEST 2004: Martin Schulze <joey@infodrom.org>
 *	Created local copy of module.h based on the content of Linux
 *	2.2 since <linux/module.h> doesn't work anymore with its
 *	recent content from Linux 2.4/2.6.
 *
 * Thu May 25 09:14:33 CEST 2006: Martin Schulze <joey@infodrom.org>
 *	Removed asm/atomic.h since it is not needed anymore.
