7f6f706641 Don't #include i386/isa/isa_dma.h - it's in isa/isavar.h now. This
driver is probably not far from being MI now anyway.

90151273b0 Quieten the bt_isa_probe() messages since they get a bit much when
the isa probe has gone hunting for a card on it's own.

c86e0744cb Poll for interrupts in bt_cmd in case they are masked. A completing
mailbox command will block the completion of an immediate command,
so we must service them for our command to succeed.

2bb789d7a3 Add a number of interrelated CAM feature enhancements and bug fixes.
NOTE:  These changes will require recompilation of any userland
applications, like cdrecord, xmcd, etc., that use the CAM passthrough
interface.  A make world is recommended.

camcontrol.[c8]:
 - We now support two new commands, "tags" and "negotiate".

	- The tags commands allows users to view the number of tagged
	  openings for a device as well as a number of other related
	  parameters, and it allows users to set tagged openings for
	  a device.

	- The negotiate command allows users to enable and disable
	  disconnection and tagged queueing, set sync rates, offsets
	  and bus width.  Note that not all of those features are
	  available for all controllers.  Only the adv, ahc, and ncr
	  drivers fully support all of the features at this point.
	  Some cards do not allow the setting of sync rates, offsets and
	  the like, and some of the drivers don't have any facilities to
	  do so.  Some drivers, like the adw driver, only support enabling
	  or disabling sync negotiation, but do not support setting sync
	  rates.

 - new description in the camcontrol man page of how to format a disk
 - cleanup of the camcontrol inquiry command
 - add support in the 'devlist' command for skipping unconfigured devices if
   -v was not specified on the command line.
 - make use of the new base_transfer_speed in the path inquiry CCB.
 - fix CCB bzero cases

cam_xpt.c, cam_sim.[ch], cam_ccb.h:

 - new flags on many CCB function codes to designate whether they're
   non-immediate, use a user-supplied CCB, and can only be passed from
   userland programs via the xpt device.  Use these flags in the transport
   layer and pass driver to categorize CCBs.

 - new flag in the transport layer device matching code for device nodes
   that indicates whether a device is unconfigured

 - bump the CAM version from 0x10 to 0x11

 - Change the CAM ioctls to use the version as their group code, so we can
   force users to recompile code even when the CCB size doesn't change.

 - add + fill in a new value in the path inquiry CCB, base_transfer_speed.
   Remove a corresponding field from the cam_sim structure, and add code to
   every SIM to set this field to the proper value.

 - Fix the set transfer settings code in the transport layer.

scsi_cd.c:

 - make some variables volatile instead of just casting them in various
   places
 - fix a race condition in the changer code
 - attach unless we get a "logical unit not supported" error.  This should
   fix all of the cases where people have devices that return weird errors
   when they don't have media in the drive.

scsi_da.c:

 - attach unless we get a "logical unit not supported" error

scsi_pass.c:

 - for immediate CCBs, just malloc a CCB to send the user request in.  This
   gets rid of the 'held' count problem in camcontrol tags.

scsi_pass.h:

 - change the CAM ioctls to use the CAM version as their group code.

adv driver:

 - Allow changing the sync rate and offset separately.

adw driver

 - Allow changing the sync rate and offset separately.

aha driver:

 - Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.

ahc driver:

 - Allow setting offset and sync rate separately

bt driver:

 - Don't return CAM_REQ_CMP for SET_TRAN_SETTINGS CCBs.

NCR driver:

 - Fix the ultra/ultra 2 negotiation bug
 - allow setting both the sync rate and offset separately

Other HBA drivers:
 - Put code in to set the base_transfer_speed field for
   XPT_GET_TRAN_SETTINGS CCBs.

b10162efe5 Make the bt isa driver work..
- fix cut/paste problem. :-)
- don't forget to call isa_dmacascade()
- reset the port after we release resources.

That last one is a trap to watch out for..  The isa bus driver uses the
same port/irq/mem/etc variables for the initial probe hints as it does
for allocation/deallocation tracking.  Releasing a resource clears the
variable and then you loose the hint during attach.. (ouch!)

d31d6be6f6 Implement an EISA new-bus framework. The old driver probe mechanism
had a quirk that made a shim rather hard to implement properly and it was
just easier to convert the drivers in one go.  The changes to the
buslogic driver go beyond just this - the whole driver was new-bus'ed
including pci and isa.  I have only tested the EISA part of this so far.

bc169999cf Improve bt_cmd() so that it has a better chance of working when there
are pending I/O transactions.  It is not clear that is works 100% of
the time under SMP, but since the bt_cmds() that are sent after other
CPUs are started are not critical, the driver will function until I
can figure out why this is the case.

984e3d8eed Add bt_port_probe() a routine shared by the EISA and ISA probe code to
determine IRQ and DRQ information.

69aac6dea7 Ask the card where our interrupt is instead of attempting to use the EISA
config info.  On early revision cards (742a), the EISA register space,
other than the location used to determine the address of the card's main

5d9e607fd1 Remove unsued variable.
If we are not transfering any data, use a non S/G ccb type that doesn't
return residual information.  It seems that some firmware revisions dislike
S/G ccbs with 0 length S/G lists.

Correct bt_cmd() so that we always honor command status that was latched
by our interrupt routine while polling for completion..

982e80577d Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.
