if fetching a config page for a sas target doesnt work then let the scsi
midlayer try to probe it anyway. this lets raid devices configured on an

check all luns on sas boards to see if the device is atapi instead of just
the first one.

provide a scsi probe hook that checks if an atapi device is plugged into
sas mpi variants. this lets the midlayer know it should send the right

this will make the cd drive work on the sun enterprise m4000 and related
machines.

add support for handling extended configuration page requests. the sas
pages are all extended, which is annoying.

oops, there was other code in the previous commit that shouldnt have gone
in. this reverts 1.90.

replace the VMWARE quirk that restricts the bus width to 16 targets with
one for all SPI controllers. krw has a sun machine with a 1030 that gets
the bus width wrong too, so since vmware emulates that type of hardware
too, we can just limit the lot of them and forget about it.

use scsi_detach_target when a device dissapears, rather than using
config_detach and cleaning the midlayer up ourselves.

oops, the eventnotify stuff was accidentally enabled with the scsiconf
changes. its not ready yet, so disable it again.
