This is a new driver for ATTO Technology's ExpressSAS series of hardware RAID
adapters.  It supports the following adapters:

    - ExpressSAS R60F
    - ExpressSAS R680
    - ExpressSAS R608
    - ExpressSAS R644

We want ppc64 to be able to select between optimised assembly
checksum routines in big endian and the generic lib/checksum.c
routines in little endian.

The lpfc driver is forcing CONFIG_GENERIC_CSUM on which means
we are unable to make the decision to enable it in the arch
Kconfig. If the option exists it is always forced on.

This got introduced in 3.10 via commit 6a7252fd ([SCSI] lpfc:
fix up Kconfig dependencies). I spoke to Randy about it and
the original issue was with CRC_T10DIF not being defined.

As such, remove the select of CONFIG_GENERIC_CSUM.

scsi_wait_scan was introduced with asynchronous host scanning as a hack

    PM/Hibernate: Wait for SCSI devices scan to complete during resume

Actually broke scsi_wait_scan because it renders
scsi_complete_async_scans() a nop for modular SCSI if you include
scsi_scans.h (which this module does).

The lack of bug reports is sufficient proof that this module is no
longer used.

This commit removes the MCA specific SCSI drivers, and the

Also, the MCA specific SCSI documentation is removed.

This patch adds support for Universal Flash Storage(UFS)
host controllers. The UFS host controller driver
includes host controller initialization method.

The Initialization process involves following steps:
 - Initiate UFS Host Controller initialization process by writing
   to Host controller enable register
 - Configure UFS Host controller registers with host memory space
   datastructure offsets.
 - Unipro link startup procedure
 - Check for connected device
 - Configure UFS host controller to process requests
 - Enable required interrupts
 - Configure interrupt aggregation

The virtio-scsi HBA is the basis of an alternative storage stack
for QEMU-based virtual machines (including KVM).  Compared to
virtio-blk it is more scalable, because it supports many LUNs
on a single PCI slot), more powerful (it more easily supports
passthrough of host devices to the guest) and more easily
extensible (new SCSI features implemented by QEMU should not
require updating the driver in the guest).

The storage driver (storvsc_drv.c) handles all block storage devices
assigned to Linux guests hosted on Hyper-V. This driver has been in the
staging tree for a while and this patch moves it out of the staging area.

James was willing to apply this patch during the 3.3-rc phase and a decision
was taken to defer this to 3.4 since Greg had queued up a bunch of storvsc
patches for 3.4. Now that Greg has applied all of the pending storvsc patches,
I am sending this patch to move this driver out of staging. Based on James'
recommendation, this patch gets rid of the unneeded files in the staging/hv

RAID attributes uses scsi_is_sdev_device() to gate some SCSI specific
checking code.  This causes two problems.  Firstly if SCSI == n just
defining scsi_is_sdev_device() to return false might not be enough to
prevent gcc from emitting the code (and thus referring to undefined
symbols), so this needs surrounding with an ifdef.  Secondly, using
scsi_is_sdev_device() when SCSI is either y or m gives a subtle
problem in the m case: raid_attrs must also be m to use the symbol.
Do the usual Kconfig jiggery-pokery to fix this.

Use libfcoe as a common FIP implementation with fcoe.
FIP or non-FIP mode is fully automatic if the firmware
supports and enables it.

Even if FIP is not supported, this uses libfcoe for the non-FIP
handling of FLOGI and its response.

Use the new lport_set_port_id() notification to capture
successful FLOGI responses and port_id resets.

While transitioning between Ethernet and FC mode, all rx and
tx FC frames are queued.  In Ethernet mode, all frames are
passed to the exchange manager to capture FLOGI responses.

Change to set data_src_addr to the ctl_src_addr whenever it
would have previously been zero because we're not logged in.
This seems safer so we'll never send a frame with a 0 source MAC.
This also eliminates a special case for sending FLOGI frames.
