Basic Queueing model (no Head of Queue or Ordered tags).
When this flag is set, SID_CmdQueue is clear. This has
causes FreeBSD to assume that the device did not support

Technically speaking it's not required to do it, has the data and the

Factor out part of exit1() into new function vmspace_exit(). Attach
to vmspace0 to allow old vmspace to be freed earlier.
Add new function, vmspace_acquire_ref(), for obtaining a vmspace
reference for a vmspace belonging to another process. Avoid changing
vmspace refcount from 0 to 1 since that could also lead to the same
vmspace being freed twice.
Change vmtotal() and swapout_procs() to use vmspace_acquire_ref().

can see the results of SPI negotiation w/o being overwhelmed
with other crap).
+ For U320 devices, check against both Settings *and* DV flags before
deciding whether we need to skip actual SPI settings for a device.
+ Go back to creating a 'physical disk' side of a raid/passthru bus that
is limited to the number of maximum physical disks. Actually, this isn't
probably *quite* right yet for one RAID volume, and if we ever end up
with finding a device that supports more than one RAID volume (not likely),
it probably won't quite be right either.
The problem here is that the creating of this 'physical' passthru sim is
just a cheap way to leverage off the CAM midlayer to do our negotiation
for us on the subentities that make up a RAID volume. It almost causes
more trouble than it is worth because we have to remember which side
we're talking to in terms of forming commands and which target ids are
real and so on. Bleah.
+ Skip trying to actually do SPI settings for the RAID volumes on the
real side of the raid/passthru bus pair- this just confuses the issue.
The underlying real physical devices will have the negotiation performed
and the Raid volume will inherit the resultant settings. At the sime time,
non-RAID devices can be on the same real bus, so *do* perform negotiations
with them.
+ At the end of doing all of the settings twiddling, *ahem*, remember to
go update the settings on the card itself (dunno how this got nuked).
At this point, negotiations *seem* to be being done (again) correctly for
both RAID volumes and their subentities. And they seem to be *mostly*
now right for other non-RAID entities on the same bus (I ended up with
3 out of 8 other disks still at narror/async- haven't the slightest
idea why yes).
Finally, negotiations on a normal bus seem to work (again).
There's still more work coming into this area, but we're in the
final stretch.
the passed target id is one of the RAID VolumeID. This result
is used to decide whether to try and do actual SPI negotiations
on the real side of the raid/passthru bus pair. The reason we
check this is that we can have both RAID volumes and real devices
on the same bus.
