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.

426da3bcfb SMP Lock struct file, filedesc and the global file list.
Seigo Tanimura (tanimura) posted the initial delta.

I've polished it quite a bit reducing the need for locking and
adapting it for KSE.

Locks:

1 mutex in each filedesc
   protects all the fields.
   protects "struct file" initialization, while a struct file
     is being changed from &badfileops -> &pipeops or something
     the filedesc should be locked.

1 mutex in each struct file
   protects the refcount fields.
   doesn't protect anything else.
   the flags used for garbage collection have been moved to
     f_gcflag which was the FILLER short, this doesn't need
     locking because the garbage collection is a single threaded
     container.
  could likely be made to use a pool mutex.

1 sx lock for the global filelist.

struct file *	fhold(struct file *fp);
        /* increments reference count on a file */

struct file *	fhold_locked(struct file *fp);
        /* like fhold but expects file to locked */

struct file *	ffind_hold(struct thread *, int fd);
        /* finds the struct file in thread, adds one reference and
                returns it unlocked */

struct file *	ffind_lock(struct thread *, int fd);
        /* ffind_hold, but returns file locked */

I still have to smp-safe the fget cruft, I'll get to that asap.

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.

282873e2c0 - Change the taskqueue locking to protect the necessary parts of a task
while it is on a queue with the queue lock and remove the per-task locks.
- Remove TASK_DESTROY now that it is no longer needed.
- Go back to inlining TASK_INIT now that it is short again.

1de1c550b1 Add locking to taskqueues. There is one mutex per task, one mutex per
queue, and a mutex to protect the global list of taskqueues.  The only
visible change is that a TASK_DESTROY() macro has been added to mirror
the TASK_INIT() macro to destroy a task before it is free'd.

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

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.

3d04a9d7e3 Once again throw out the calculation of si_iosize_max and set it to 64K.
Although it can go higher, it is not safe to so do on arrays with many
members.  Compromise by adding a tunable, "hw.aac.iosize_max" that can be
set at boottime.  Also document in the aac(4) manpage.

da4c1ce305 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.

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.
