Subject: pata_ali: more work
From: Alan Cox <alan@xxxxxxxxxxxxxxxxxxx>
Still don't know why some people see problems with ATAPI devices
specifically but here are some more small fixes done while searching for
the root problem (some of these fixes are overconservative but that can be
fixed *after* the thing works fully)
