Merge tag 'scsi-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi

Pull SCSI updates from James Bottomley:
 "This patch set is a lot of driver updates for qla4xxx, bfa, hpsa,
  qla2xxx.  It also removes the aic7xxx_old driver (which has been
  deprecated for nearly a decade) and adds support for deadlines in
  error handling"

-	  WARNING This driver is an older aic7xxx driver and is no longer
-	  under active development.  Adaptec, Inc. is writing a new driver to
-	  take the place of this one, and it is recommended that whenever
-	  possible, people should use the new Adaptec written driver instead
-	  of this one.  This driver will eventually be phased out entirely.
-
-	  This is support for the various aic7xxx based Adaptec SCSI
-	  controllers. These include the 274x EISA cards; 284x VLB cards;
-	  2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
-	  motherboard based SCSI controllers from Adaptec. It does not support
-	  the AAA-13x RAID controllers from Adaptec, nor will it likely ever
-	  support them. It does not support the 2920 cards from Adaptec that
-	  use the Future Domain SCSI controller chip. For those cards, you
-	  need the "Future Domain 16xx SCSI support" driver.
-
-	  In general, if the controller is based on an Adaptec SCSI controller
-	  chip from the aic777x series or the aic78xx series, this driver
-	  should work. The only exception is the 7810 which is specifically
-	  not supported (that's the RAID controller chip on the AAA-13x
-	  cards).
-
-	  Note that the AHA2920 SCSI host adapter is *not* supported by this
-	  driver; choose "Future Domain 16xx SCSI support" instead if you have
-	  one of those.
-
-	  Information on the configuration options for this controller can be
-	  found by checking the help file for each of the available
-	  configuration options. You should read
-	  <file:Documentation/scsi/aic7xxx_old.txt> at a minimum before
-	  contacting the maintainer with any questions.  The SCSI-HOWTO,
-	  available from <http://www.tldp.org/docs.html#howto>, can also
-	  be of great help.
-
-	  To compile this driver as a module, choose M here: the
-	  module will be called aic7xxx_old.

- * Further driver modifications made by Doug Ledford <dledford@redhat.com>
- *
- * Copyright (c) 1997-1999 Doug Ledford
- *
- * These changes are released under the same licensing terms as the FreeBSD
- * driver written by Justin Gibbs.  Please see his Copyright notice above
- * for the exact terms and conditions covering my changes as well as the
- * warranty statement.
- *
- * Modifications made to the aic7xxx.c,v 4.1 driver from Dan Eischen include
- * but are not limited to:
- *
- *  1: Import of the latest FreeBSD sequencer code for this driver
- *  2: Modification of kernel code to accommodate different sequencer semantics
- *  3: Extensive changes throughout kernel portion of driver to improve
- *     abort/reset processing and error hanndling
- *  4: Other work contributed by various people on the Internet
- *  5: Changes to printk information and verbosity selection code
- *  6: General reliability related changes, especially in IRQ management
- *  7: Modifications to the default probe/attach order for supported cards
- *  8: SMP friendliness has been improved
- *
- * Overall, this driver represents a significant departure from the official
- * aic7xxx driver released by Dan Eischen in two ways.  First, in the code
- * itself.  A diff between the two version of the driver is now a several
- * thousand line diff.  Second, in approach to solving the same problem.  The
- * problem is importing the FreeBSD aic7xxx driver code to linux can be a
- * difficult and time consuming process, that also can be error prone.  Dan
- * Eischen's official driver uses the approach that the linux and FreeBSD
- * drivers should be as identical as possible.  To that end, his next version
- * of this driver will be using a mid-layer code library that he is developing
- * to moderate communications between the linux mid-level SCSI code and the
- * low level FreeBSD driver.  He intends to be able to essentially drop the
- * FreeBSD driver into the linux kernel with only a few minor tweaks to some
- * include files and the like and get things working, making for fast easy
- * imports of the FreeBSD code into linux.
- *
- * I disagree with Dan's approach.  Not that I don't think his way of doing
- * things would be nice, easy to maintain, and create a more uniform driver
- * between FreeBSD and Linux.  I have no objection to those issues.  My
- * disagreement is on the needed functionality.  There simply are certain
- * things that are done differently in FreeBSD than linux that will cause
- * problems for this driver regardless of any middle ware Dan implements.
- * The biggest example of this at the moment is interrupt semantics.  Linux
- * doesn't provide the same protection techniques as FreeBSD does, nor can
- * they be easily implemented in any middle ware code since they would truly
- * belong in the kernel proper and would effect all drivers.  For the time
- * being, I see issues such as these as major stumbling blocks to the 
- * reliability of code based upon such middle ware.  Therefore, I choose to
- * use a different approach to importing the FreeBSD code that doesn't
- * involve any middle ware type code.  My approach is to import the sequencer
- * code from FreeBSD wholesale.  Then, to only make changes in the kernel
- * portion of the driver as they are needed for the new sequencer semantics.
- * In this way, the portion of the driver that speaks to the rest of the
- * linux kernel is fairly static and can be changed/modified to solve
- * any problems one might encounter without concern for the FreeBSD driver.
- *
- * Note: If time and experience should prove me wrong that the middle ware
- * code Dan writes is reliable in its operation, then I'll retract my above
- * statements.  But, for those that don't know, I'm from Missouri (in the US)
- * and our state motto is "The Show-Me State".  Well, before I will put
- * faith into it, you'll have to show me that it works :)

- * AIC7XXX_STRICT_PCI_SETUP
- *   Should we assume the PCI config options on our controllers are set with
- *   sane and proper values, or should we be anal about our PCI config
- *   registers and force them to what we want?  The main advantage to
- *   defining this option is on non-Intel hardware where the BIOS may not
- *   have been run to set things up, or if you have one of the BIOSless
- *   Adaptec controllers, such as a 2910, that don't get set up by the
- *   BIOS.  However, keep in mind that we really do set the most important
- *   items in the driver regardless of this setting, this only controls some
- *   of the more esoteric PCI options on these cards.  In that sense, I
- *   would default to leaving this off.  However, if people wish to try
- *   things both ways, that would also help me to know if there are some
- *   machines where it works one way but not another.
- *
- *   -- July 7, 17:09
- *     OK...I need this on my machine for testing, so the default is to
- *     leave it defined.
- *
- *   -- July 7, 18:49
- *     I needed it for testing, but it didn't make any difference, so back
- *     off she goes.
- *
- *   -- July 16, 23:04
- *     I turned it back on to try and compensate for the 2.1.x PCI code
- *     which no longer relies solely on the BIOS and now tries to set
- *     things itself.

- *   This option enables a lot of extra printk();s in the code, surrounded

- *   statements and the extra checks can get to where it actually does have
- *   an impact on CPU usage and such, as well as code size.  Disabling this
- *   define will keep some of those from becoming part of the code.
- *
- *   NOTE:  Currently, this option has no real effect, I will be adding the
- *   various #ifdef's in the code later when I've decided a section is
- *   complete and no longer needs debugging.  OK...a lot of things are now
- *   surrounded by this define, so turning this off does have an impact.
