From 6593178dd46d64a5bcb0402a4f3acd95b0687abd Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Fri, 18 Nov 2005 23:13:33 +0100 Subject: [PATCH] [PATCH] ide: fix ide_toggle_bounce() to not try to bounce if we have an IOMMU The following patch fixes a crash caused by attempting to bounce buffer when an IDE CD-ROM is used on a machine with an IO-MMU. [At least, this patch fixes things so I can use my IDE CD-ROM behind an ns87415 on a HP PA-RISC workstation.] Signed-off-by: James Bottomley Signed-off-by: Kyle McMartin Signed-off-by: Bartlomiej Zolnierkiewicz --- Reading git-format-patch failed
