From eb0df9962d97f7156a0870aced9018bf5c8f54c1 Mon Sep 17 00:00:00 2001 From: "mike.miller@hp.com" Date: Fri, 10 Jun 2005 14:51:04 -0500 Subject: [PATCH] [SCSI] cciss 2.6 DMA mapping Patch removes our homegrown DMA masks and uses the ones defined in the kernel. This patch replaces the broken one I sent in earlier. It has been tested and works. Please discard the first submission.
