2f4bfb29bb Fix GET_TRAN_SETTINGS to be more correct.
Don't allow SCSI resets on the 5400S card, it seems to cause problems with
certain backplanes.

fe3cb0e1ec Add a CAM interface to the aac driver. This is useful in case you should
ever connect a SCSI Cdrom/Tape/Jukebox/Scanner/Printer/kitty-litter-scooper
to your high-end RAID controller.  The interface to the arrays is still
via the block interface; this merely provides a way to circumvent the
RAID functionality and access the SCSI buses directly.  Note that for
somewhat obvious reasons, hard drives are not exposed to the da driver
through this interface, though you can still talk to them via the pass
driver.  Be the first on your block to low-level format unsuspecting
drives that are part of an array!

To enable this, add the 'aacp' device to your kernel config.

cbfd045b10 Prepare for a major update to the aac driver:
Update the aac driver with the new crashdump api.
	Protect sync fibs with a mutex.
	Align all DMA buffers on a PAGE_SIZE boundary.

fe94b852b3 Don't attach to Dell PERC2/QC cards that have a firmware rev of 1.x. This
check is complicated by the fact that the Adaptec 5400S cards claim to use
1.x firmware also.  PERC2/QC 1.x firmware is not compatible with this driver
and will cause a system hang.

b3457b5173 Add functionality and fix bugs so the driver will work with soon-to-be
released management apps.

1.  Implement poll().  This will check for queued aif's so that a
    subsequent ioctl call to retrieve the next aif will not block.
2.  Don't catch signals when sleeping on a fib sent from userland.  This
    causes a race and panic due to the pthread context switcher waking
    up the tsleep at inopportune times.
3.  Fix some whitespace nits.

36e0bf6e9c Mega update to the aac driver.
1.  Correctly handle commands initiated by the adapter.  These commands
    are defered to a kthread responsible for their processing, then are
    properly returned to the controller.
2.  Add/remove disk devices when notified by the card that a container was
    created/deleted/offline.
3.  Implement crashdump functionality.
4.  Support all ioctls needed for the management CLI to work.  The linux
    version of this app can be found at the Dell or HP website.  A native
    version will be forthcoming.

f6c4dd3f48 Bugfixes. Close a race and logic bug in the timeout handling, don't call the
interrupt handler from the upper half, etc.  This fixes some serious stability
problems that we were seeing on our production server.  These patches have
been tested for almost 6 months and are a highly recommended MFC candidate.

ed34d0ade2 Turn on interrupt-entropy harvesting for all/any mass storage devices
I could find. I have no doubt missed a couple.

Interrupt entropy harvesting is still conditional on the
kern.random.sys.harvest_interrupt sysctl.

0b94a66e3f Major bugfix and minor update. This should resolve the current issues
with the driver locking up under load.

 - Restructure so that we use a static pool of commands/FIBs, rather than
   allocating them in clusters.  The cluster allocation just made things
   more complicated, and allowed us to waste more memory in peak load
   situations.
 - Make queueing macros more like my other drivers.  This adds queue stats
   for free.  Add some debugging to take advantage of this.
 - Reimplement the periodic timeout scan.  Kick the interrupt handler
   and the start routine every scan as well, just to be safe.  Track busy
   commands properly.
 - Bring resource cleanup into line with resource allocation.  We should
   now clean up correctly after a failed probe/unload/etc.
 - Try to start new commands when old ones are completed.  We weren't doing
   this before, which could lead to deadlock when the controller was full.
 - Don't try to build a new command if we have found a deferred command.
   This could cause us to lose the deferred command.
 - Use diskerr() to report I/O errors.
 - Don't bail if the AdapterInfo structure is the wrong size.  Some variation
   seems to be normal.  We need to improve our handing of 2.x firmware sets.
 - Improve some comments in an attempt to try to make things clearer.
 - Restructure to avoid some warnings.
