While trying to get SUSE's SLES9 working on system with more than 4GB we've
noticed that SCSI layer happilly passes addresses over 4GB to the buslogic
driver, which is quite a big problem as buslogic can generate only 32bit
busmastering cycles.
Fortunately in the current kernels this problem does not exist anymore as
SCSI layer now assumes 4GB capable device by default, but it is still good
idea to pass correct device structure to the SCSI layer. If nothing else,
/sys/block/sda/device now points to
/sys/devices/pci0000:00/0000:00:10.0/host0/... instead of
/sys/devices/platform/host0/... like it did in the past.
Change does nothing for ISA based BusLogic adapters, they'll still end
under platform (and they are probably broken for long time as I do not see
anything forcing ISA 16MB limit for them).

scsi_cmnd->serial_number_at_timeout doesn't serve any purpose
anymore. All serial_number == serial_number_at_timeout tests
are always true in abort callbacks. Kill the field. Also, as
->pid always equals ->serial_number and ->serial_number
doesn't have any special meaning anymore, update comments
above ->serial_number accordingly. Once we remove all uses of
this field from all lldd's, this field should go.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
