af55ff675a [SCSI] sd: Support for SCSI disk (SBC) Data Integrity Field
Support for controllers and disks that implement DIF protection
information:

 - During command preparation the RDPROTECT/WRPROTECT must be set
   correctly if the target has DIF enabled.

 - READ(6) and WRITE(6) are not supported when DIF is on.

 - The controller must be told how to handle the I/O via the
   protection operation field in scsi_cmnd.

 - Refactor the I/O completion code that extracts failed LBA from the
   returned sense data and handle DIF failures correctly.

 - sd_dif.c implements the functions required to prepare and complete
   requests with protection information attached.

072b91f9c6 [SCSI] ibmvfc: IBM Power Virtual Fibre Channel Adapter Client Driver
This patch adds a new device driver to support the Virtual Fibre Channel
interface on IBM Power based servers. The Virtual I/O Server on IBM Power
servers utilizes N-Port ID Virtualization to export a Virtual Fibre Channel
adapter to the client. This driver is the client device driver.

a6a8d9f87e [SCSI] scsi_dh: add infrastructure for SCSI Device Handlers
Some of the storage devices (that can be accessed through multiple paths),
do need some special handling for
	1. Activating the passive path of the storage access.
	2. Decode and handle the special sense codes returned by the devices.
	3. Handle the I/Os being sent to the passive path, especially
           during the device probe time.
when accessed through multiple paths.

As of today this special device handling is done at the dm-multipath
layer using dm-handlers. That works well for (1); for (2) to be handled
at dm layer, scsi sense information need to be exported from SCSI to dm-layer,
which is not very attractive; (3) cannot be done at all at the dm layer.

Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

62ac5aedc5 [SCSI] dpt_i2o: 64 bit support
This is the code to actually support 64 bit platforms. 64 bit
DMA is enabled on both x86_32 PAE and 64 bit platforms.

This code is based in part on the unofficial adaptec 64-bit
dpt_i2o driver update that I got from Mark Salyzyn at Adaptec.

78b4b05db5 [SCSI] BusLogic: make FlashPoint support x86-32 only
We've verified that there are 64 bit and endianness problems in the
flashpoint driver.  Reverse the logic of CONFIG_OMIT_FLASHPOINT (make
it CONFIG_SCSI_FLASHPOINT) and make it depend on X86_32 so it can't
appear for any other architectures.  Long term, if someone chooses,
they could make FlashPoint 64 bit compliant (it looks like its a
question of fixing up the sizes in some of the packed descriptors)

67951f6380 [SCSI] Fix dependency problems in SCSI drivers
We have several drivers that don't list SCSI as a dependency in
Kconfig.  That leads to them potentially being selected as Y even if
SCSI is M (which will produce a build failure).  Fix this by making
the if SCSI_LOWLEVEL that goes around all the drivers a tristate
forcing them all automatically to inherit the value of SCSI.

9927c68864 [SCSI] ses: add new Enclosure ULD
This adds support to SCSI for enclosure services devices. It also makes
use of the enclosure services added in an earlier patch to display the
enclosure topology in sysfs.

At the moment, the enclosures are SAS specific, but if anyone actually
has a non-SAS enclosure that follows the SES-2 standard, we can add that
as well.

On my Vitesse based system, the enclosures show up like this:

sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/
total 0
-r--r--r-- 1 root root 4096 2008-02-03 15:44 components

--w------- 1 root root 4096 2008-02-03 15:44 uevent

And the individual occupied slots like this:

total 0
-rw-r--r-- 1 root root 4096 2008-02-03 15:45 active

--w------- 1 root root 4096 2008-02-03 15:45 uevent

You can flash the various blinky lights by echoing to the fault and locate files.

>From the device's point of view, you can see it has an enclosure like this:

sparkweed:~# ls /sys/class/scsi_disk/0\:0\:0\:0/device/

enclosure_component:SLOT 001  model          scsi_generic:sg0
evt_media_change              power          scsi_level

Note the enclosure_component:SLOT 001 which shows where in the enclosure
this device fits.

The astute will notice that I'm using SCSI VPD Inquiries to identify the
devices.  This, unfortunately, won't work for SATA devices unless we do
some really nasty hacking about on the SAT because the only think that
knows the SAS addresses for SATA devices is libsas, not libata where the
SAT resides.

928923c76b Introduce CONFIG_CHECK_SIGNATURE
Introduce CONFIG_CHECK_SIGNATURE to control inclusion of check_signature()
and avoid problems on platforms that don't have readb().

Let the few legacy (ISA || PCI || X86) drivers that need check_signature()
select CONFIG_CHECK_SIGNATURE.

7689e82efd [SCSI] don't build scsi_dma_{map,unmap} for !HAS_DMA
With

 dma-mapping-prevent-dma-dependent-code-from-linking-on.patch

scsi fails to build on !HAS_DMA architectures:

drivers/built-in.o(.text+0x20af6): In function `scsi_dma_map':
: undefined reference to `dma_map_sg'
drivers/built-in.o(.text+0x20b5c): In function `scsi_dma_unmap':
: undefined reference to `dma_unmap_sg'

I split those functions out into a new file. Builds on s390 and i386.

Move scsi_dma_{map,unmap} into scsi_lib_dma.c which is only build if
HAS_DMA is set.

Add help info for BLK_DEV_SD referring to its use in
SATA or PATA driver configurations.

Add help text for "ATA" indicating that it probably needs
some SCSI config symbols enabled in order to be useful.
