From b5683557331b129658ab435391df527ef72d63dc Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Thu, 15 Sep 2005 08:59:36 -0500 Subject: [SCSI] atp870u: fix memory addressing bug From: Alan Cox The virt_to_bus() wasn't correctly taken out of this driver. It needs to be able to track both physical and virtual addresses for its prd table. Update the driver to do this with separate tracking entries.
