From e69dc6dc7d90312371265da4c08fee9482cf08e9 Mon Sep 17 00:00:00 2001
From: "Justin T. Gibbs" <gibbs@overdrive.btc.adaptec.com>
Date: Tue, 7 Jan 2003 05:58:41 -0700
Subject: aic7xxx and aic79xx driver updates:

	o Correct memory mapped I/O test for legacy controllers
	  that do not have the "auto-access-pause" feature.
	o Prevent NMIs from triggering should the MMAP I/O test fail.
	o Fix aic7770 (EISA/VLB) controller regression.
	o Kill a few compiler warnings.
