lk 2.5.2-pre1: sg, advansys + scsi_debug

Here are some patches to get broken SCSI drivers going in lk 2.5.2-pre1 :

http://www.torque.net/sg/p/advansys.c252p1min.diff
is a minimal hack to get the advansys adapter driver going. Hopefully a more solid patch from its maintainer will follow shortly.

http://www.torque.net/sg/p/sg252p1_2.diff.gz resyncs the sg driver with lk 2.4.17 and adds some scatterlist changes required by 2.5 .

http://www.torque.net/sg/p/scsi_debug252p1.diff.gz replaces the existing scsi_debug "fake" adapter driver with something that is like a ram disk, that can accept fdisk, mkfs, mount etc. I have used it in the past to test Richard Gooch's sd-many patch.
