72d39fea90 [SCSI] initio: Convert into a real Linux driver and update to modern style
This is a mix of a grand clean up I did and a reworking of the hotplug
support by Christoph. In testing it works as well as the previous code
did (that is -quite badly-) but we can now read it and as it settles in
actually debug the long standing problems it shares with the old driver.

9d399cc7fe [SCSI] aacraid: add support for FUA
Back in the beginning of last year we disabled mode page 8 and mode page
3f requests through device quirk bits instead of enhancing the driver to
respond to these mode pages because there was no apparent added value.

The Firmware that supports the new communication commands supports the
ability to force a write around of the adapter cache on a command by
command basis. In the attached patch we enable mode page 8 and 3f and
spoof the results as needed in order to *convince* the layers above to
submit writes with the FUA (Force Unit Attention) bit set if the file
system or application requires it, if the Firmware supports the write
through, or instead to submit a SYNCHRONIZE_CACHE if the Firmware does
not. The added value here is for file systems that benefit from this
functionality and for clustering or redundancy scenarios.

Caveats: By convince, we are responding with a minimal short 3 byte
content mode page 8, with only the data the SCSI layer needs and that we
can fill confidently. Applications that require the customarily larger
mode page 8 results may be confused by this(?). The FUA, or the
SYNCHRONIZE_CACHE only affect the cache on the controller. Our firmware
by default ensure that the underlying physical drives of the array have
their cache turned off so normally this is not a problem.

This attached patch is against current scsi-misc-2.6 and was unit tested
on RHEL5. Since this is a feature enhancement, it should not be
considered for any current stabilization efforts.

1dfcda06a6 [SCSI] kill scsi host template suspend/resume
With libata converted to use sdev->manage_start_stop for suspend and
resume, sht->suspend/resume() has no user left and low level
suspend/ressume should be taken care of by low level driver's
suspend/resume callbacks (e.g. PCI or PCMCIA driver callbacks).  This
patch removes sht->suspend/resume() callbacks.

This change is suggested by Christoph Hellwig.

This is basically a straight conversion.  I have one of these things, so

However, previously it panic'd in the interrupt, now it completes a bus

e8edc6e03a Detach sched.h from mm.h
First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig

On digging into it, it turned out that the customer was probing an
aacraid device with an INQUIRY of 8 bytes.  The way aacraid works, it
was blindly trying to use aac_internal_transfer to copy the container
name to byte 16 of the inquiry data, resulting in a negative transfer
length.  It then copies over the whole of kernel memory before
dropping off the end.

2ab01efd1d [SCSI] aacraid: Correct sa platform support. (Was: [Bug 8469] Bad EIP value on pentium3 SMP kernel-2.6.21.1)
http://bugzilla.kernel.org/show_bug.cgi?id=8469

As discussed in the bugzilla outlined below, we have an sa based
(Mustang) RAID adapter on the system, a Dell PERC2/QC. Affected
controllers are HP NetRAID, Adaptec AAC-364, Dell PERC2/QC or Adaptec
5400S. This problem  coincides with the introduction of the adapter_comm
and adapter_deliver platform functions (Message [PATCH 1/4] aacraid:
rework communication support code, January 23 2007, which initially
migrated to 2.6.21)

The panic occurs with an uninitialized adapter_deliver platform function
pointer. The enclosed patch, unmodified as tested by Rainer, solves the
problem.

d116a7bc6a [SCSI] stex: fix reset recovery for console device
After reset completed, the scsi error handler sends out TEST_UNIT_READY
to the device. For 'normal' devices the command will be handled by firmware.
However, because the RAID console only interfaces to scsi mid layer, the
firmware will not process the command for it. This will make the console to
be offlined right after reset. Add the handling in driver to fix this problem.

e0b2e597d5 [SCSI] stex: fix id mapping issue
The correct internal mapping of stex controllers should be:
id:0~15, lun:0~7 (st_shasta)
id:0, lun:0~127 (st_yosemite)
id:0~127, lun:0 (st_vsc and st_vsc1)

This patch reports the internal mapping to scsi mid layer,  eliminating
the translation between scsi mid layer and firmware. To achieve this
goal, we also need to:
-- fail the REPORT_LUNS command for st_shasta because the
   firmware is known to not report all actual luns
-- add an entry in scsi_devindo.c to force sequential lun scan
   (for st_shasta controllers)
-- fail the REPORT_LUNS command for console device
-- remove special handling of REPORT_LUNS command for
   st_yosemite, as there is no translation mapping now

a53eb5e060 [SCSI] FC Transport support for vports based on NPIV
This patch provides support for FC virtual ports based on NPIV.
For information on the interfaces and design, please read the
Documentation/scsi/scsi_fc_transport.txt file enclosed within
the patch.

The RFC was originally posted here:
http://marc.info/?l=linux-scsi&m=117226959918393&w=2

Changes from the initial RFC:
- Bug fix: needed a transport_class_unregister() for the vport class
- Create a symlink to the vport in the shost device if it is not the
    parent of the vport.
- Made symbolic name writable so it can be set after creation
- Made the temporary fc_vport_identifiers struct private to the
transport.
- Deleted the vport_id field from the vport. I couldn't find any good
  use for it (and symname is a good replacement).
- Made the vport_state and vport_last_state "private" attributes.
  Added the fc_vport_set_state() helper function to manage state
  transitions
- Updated vport_create() to allow a vport to be created in a disabled
  state.
- Added INITIALIZING and FAILED vport states
- Added VPCERR_xxx defines for errors to be returned from vport_create()
- Created a Documentation/scsi/scsi_fc_transport.txt file that describes
  the interfaces and expected LLDD behaviors.

463fc696ed [SCSI] ipr: Use PCI-E reset API for new ipr adapter
Use a newly added PCI API to issue a PCI Fundamental reset
(warm reset) to a new ipr PCI-E adapter. Typically, the
ipr adapter uses the start BIST bit in config space to reset
an adapter. Issuing start BIST on this particular adapter
results in the PCI-E logic on the card losing sync, which
causes PCI-E errors, making the card unusable. The only reset
mechanism that exists on this hardware that does not have this
problem is PCI Fundamental reset (warm reset).

9e4d4a5d71 [SCSI] aacraid: superfluous adapter reset for IBM 8 series ServeRAID controllers
The kexec patch introduced a superfluous (and otherwise inert) reset of
some adapters. The register can have a hardware default value that has
zeros for the undefined interrupts. This patch refines the test of the
interrupt enable register to focus on only the interrupts that affect
the driver in order to detect if an incomplete shutdown of the Adapter
had occurred (kdump).
