f0c568a478 [SCSI] mvumi: Add Marvell UMI driver
The Marvell Universal Message Interface (UMI) defines a messaging
interface between host and Marvell products (Plato, for example). It
considers situations of limited system resource and optimized system
performance.
	UMI driver translates host request to message and sends message
to FW via UMI, FW receives message and processes it, then sends response
to UMI driver.
	FW generates an interrupt when it needs to send information or
response to UMI driver

853e2bd210 [SCSI] bnx2fc: Broadcom FCoE offload driver
This driver is for Broadcom Netxtreme II 57712 chip. The following
patch contains the driver sources for bnx2fc driver.  libfc/libfcoe
changes to enable bnx2fc have already gone through the fcoe
tree. bnx2fc is a SCSI low level driver that interfaces with SCSI
midlayer, libfc, libfcoe, cnic modules.  bnx2fc driver uses services
of libfc for slow path operations such as FIP and fabric
discovery. The fast path IO perations are performed after offloading
the session information to the underlying FCoE firmware.

42e9a92fe6 [SCSI] libfc: A modular Fibre Channel library
libFC is composed of 4 blocks supported by an exchange manager
and a framing library. The upper 4 layers are fc_lport, fc_disc,
fc_rport and fc_fcp. A LLD that uses libfc could choose to
either use libfc's block, or using the transport template
defined in libfc.h, override one or more blocks with its own
implementation.

The EM (Exchange Manager) manages exhcanges/sequences for all
commands- ELS, CT and FCP.

The framing library frames ELS and CT commands.

The fc_lport block manages the library's representation of the
host's FC enabled ports.

The fc_disc block manages discovery of targets as well as
handling changes that occur in the FC fabric (via. RSCN events).

The fc_rport block manages the library's representation of other
entities in the FC fabric. Currently the library uses this block
for targets, its peer when in point-to-point mode and the
directory server, but can be extended for other entities if
needed.

The fc_fcp block interacts with the scsi-ml and handles all
I/O.

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.

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.

1ecd3902c6 [SCSI] fc4: remove this and all associated drivers
This code has been slowly rotting for about eight years.  It's currently
impeding a few SCSI cleanups, and nobody seems to have hardware to test
it any more.  I talked to Dave Miller about it, and he agrees we can
delete it.  If anyone wants a software FC stack in future, they can
retrieve this driver from git.

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.
