OK, here's the patch, without the m68k generic iomap changes.
If there are no objections, I will commit it to our CVS repository so
Geert can send it upstream (with proper Signed-Off-By: headers and
everything).
This patch is relative to the m68k CVS repository, which is at kernel
version 2.6.18.
I have renamed the mvme16x.c and bvme6000.c files to mvme16x_scsi.c and
bvme6000_scsi.c respectively, I'm not sure if this is a good idea
though.
Kind regards,
Kars.
