Give panic format string to pacify clang warning.

Whitespace cleanup, in advance of next sync with Adaptec's driver. No
functional change.

Sync with the official Adaptec vendor driver:

[1] Add the support for the NARK controller which seems a variant of
the i960Rx.
[2] Split up memory regions and other resources in 2 different parts
as long as NARK uses them separately (it is not clear to me
why though as long as there are no more informations available
on this controller). Please note that in all the other cases,
the regions overlaps leaving the default behaviour for all the
other controllers.
[3] Implement a clock daemon responsible for maintain updated the
wall clock time of the controller (run any 30 minutes)*.

* Please note that originally, in the Adaptec driver, the clock daemon
is not implemented with callouts as in our in-tree driver.

Diff reduction to Adaptec's driver (around build 15317): catch up with a
change in debugging routines.

The fwprintf macro in the AAC_DEBUG case (mapping to printf) isn't from the
Adaptec driver.

aac_intr0 rotted long ago, remove it.

Retire the FreeBSD 4.x compat code and __FreeBSD_version checks from the aac
driver.

Complete the repo-copy of aac_ioctl.h from sys/dev/aac/to sys/sys.

Cast printf'ed values to intmax_t.

Remove the use of AACQ_COMPLETE here since there is no longer a completion
queue.

Make LINT compile on amd64

Use __FBSDID().
Also some minor style cleanups.

Use bioq_flush() to drain a bio queue with a specific error code.
Retain the mistake of not updating the devstat API for now.

Spell bioq_disksort() consistently with the remaining bioq_*().

#include <geom/geom_disk.h> where this is more appropriate.

Include <sys/conf.h> rather than trusting <sys/disk.h> to do so.

Centralize the devstat handling for all GEOM disk device drivers
in geom_disk.c.

As a side effect this makes a lot of #include <sys/devicestat.h>
lines not needed and some biofinish() calls can be reduced to
biodone() again.

Major bugfixes for large memory and fast systems.

aac.c:
Re-arrange the interrupt handler to optimize the common case of
the adapter interrupting us because one or more commands are complete,
and do a read across the pci bus to ensure that all posted status
writes are flushed. This should close a race that could cause command
completion interrupts to be lost.
Follow the spec a bit closer when filling out command structures.
Enable the Fast Response feature to eliminate the need for the card
to DMA successfull command completions back into host memory.
Tell the controller how much physical memory we have. Without this
there was a chance that our DMA regions would collide with the
memory window used by the cache on the controller. The result would
be massive data corruption. This seemed to mainly affect systems with
>2GB of memory.
Fix a few whitespace problems.

aac_debug.c:
Add an extra diagnostic when printing out commands.

aac_disk.c:
Add extra sanity checks.

aacreg.h:
Prepare for making this 64-bit clean by reducing the use of enumeration
types in structures.

Many thanks to Justin Gibbs for helping track these down.

Fix deprecated use of label at end of compound statement

Constify a debug function arg that we pass __func__ to in order to pacify
gcc-3.1's 'const char *__func__;'

Staticise the aac devclass.

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.

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.

MFC-after: 4.4-RELEASE

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.

Reformat for 80 columns. Sorry, but I had to do it.

This is an MFC candidate.

Add the AAC_DEBUG option to enable debugging in the aac driver.

Correct a race condition in the interrupt handler where the
controller may queue a fib to a response queue after the driver
has serviced the queue but before the interrupt is cleared.
This could leave a completed fib stranded in the response queue
unless another I/O completed and generated another interrupt.

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.
