8b11740052 The divide by zero panic must have been due to a bogus
period value. I suppose the BT adapter driver should be
fixed, but more importantly we should protect against
dividing by zero.

53372d3a6d Fix a problem with the cd(4) driver -- the CAMGETPASSTHRU ioctl wouldn't
succeed if there was no media in the drive.

This was broken in rev 1.72 when the media check was added to cdioctl().

For now, check the ioctl group to decide whether to check for media or not.
(We only need to check for media on CD-specific ioctls.)

df8f908079 Restore queue depth settings across tag disable events. The system often
disables tag queuing temporarily in order to allow controllers a window
to safely perform transfer negotiation with non-compliant devices.  Before
this change, CAM would restore the queue depth to the controller specified
maximum or device quirk level rather than any depth determined by reactions
to QUEUE FULL/BUSY events or an explicit user setting.

During device probe, initialize the flags field for XPT_SCAN_BUS.
The uninitialized value often confused CAM into not bothering to
issue an AC_FOUND_DEVICE async event for new devices.  The reason
this bug wasn't reported earlier is that CAM manually announces
devices after the initial system bus scans.

ef3cf714a4 Provide locking for the ccb_bioq. This allows xpt_done() to be called without
Giant held.  In camisr(), move the ccb_bioq elements to a temporary local list
and then process the elements off of that list.  This enables the list to be
processed by only taking the ccb_bioq_lock once and only for a very short
time.

ccb_bioq_lock is a leaf mutex, so it's fine to call xpt_done() with other
locks held.  This is just a very minor step in the work to lock CAM, but
it allows us to avoid some messy locking/unlock dances in certain drivers.

4379219537 Boot away another stackgap (one of the lest ones in linuxlator/i386) by
providing special version of CDIOCREADSUBCHANNEL ioctl(), which assumes that
result has to be placed into kernel space not user space. In the long run
more generic solution has to be designed WRT emulating various ioctl()s
that operate on userspace buffers, but right now there is only one such
ioctl() is emulated, so that it makes little sense.

f4322bc884 This is a somewhat imperfect means to try and bring FreeBSD forward in
its ability to automatically scan and attach luns for modern storage
which has luns in the 0..1000 range, not 0..7.

The correct thing would be to do REPORT LUNS for devices whose LUN0
version shows a version >= SCSI3, but lacking that we should be able
to search higher than LUN 7 if we're >= SCSI3 with no ill effects.

This change keeps all of the QUIRK_HILUNS quirks, obeys the QUIRK_NOLUNS,
and introduces a QUIRK_NOHILUNS which will keep searches above LUN 7
happening for devices that report >= SCSI3 compliance. I doubt the latter
will be needed, but you never know.

This allowed me to randomly scan and attach  > 500 disks at a time in
a situation where quirking for QUIRK_HILUNS wasn't practical (the
vendor id and product id changes of the virtualization changes
constantly).

709a936f1f Correct an off-by-one in the calculation of the inquiry buffer length
to request from devices during the "long inquiry" portion of our probe.
This same bug was fixed in the 4.x stream a few years ago, but the fix
was never propogated to -current.

This fix is slightly different than in -stable:

 o Use offsetof() instead of a hard coded constant so as the make
   the code more self-explainatory.

 o Round odd long inquiry lengths up so as to avoid tickling ignore
   wide residue bugs in broken parallel SCSI devices running with a
   wide transfer negotiation.

ad3b9257c2 Add locking to the kqueue subsystem. This also makes the kqueue subsystem
a more complete subsystem, and removes the knowlege of how things are
implemented from the drivers.  Include locking around filter ops, so a
module like aio will know when not to be unloaded if there are outstanding
knotes using it's filter ops.

Currently, it uses the MTX_DUPOK even though it is not always safe to
aquire duplicate locks.  Witness currently doesn't support the ability
to discover if a dup lock is ok (in some cases).
