1bff6cc8fb [SCSI] qla2xxx: Correctly read sfp single byte mailbox register.
When reading a single byte using the READ SFP mailbox command, the
single byte of data is returned in MB[1] and not MB[8].

The reason that MB[8] was being used is that the spec was unclear
as it evolved over time; and we have not needed to read a single
byte until recently.

a command can be sent, and send it a soft reset command, then

This is to get kdump to work on all the "non-resettable" controllers
(except 64xx controllers which can't be reset due to the potentially
shared cache module.)

3699d92a4d [SCSI] tcm_fc: Adding FC_FC4 provider (tcm_fc) for FCoE target (TCM - target core) support
This is a comprehensive patch for FC-FC4 provider. tcm_fc is a FC-FC4
provider which glues target core (TCM) with Fiber channel library
(libfc). tcm_fc uses existing FC4 provider hooks from Fiber channel
library. This Fiber channel library is used by FCoE (transport - FC
over Ethernet) protocol driver as well.

Combination of modules such as Fiber channel library, tcm_fc, TCM
target core, and FCoE protocol driver enables functional FCoE target.

This patch includes initial commit for tcm_fc plus additional
enhancement, bug fixes.

This tcm_fc module essentially contains 3 entry points such as "prli",
"prlo", "recv".  When process login request (ELS_PRLI) request is
received, Fiber channel library (libfc) module calls passive providers
(FC-FC4, tcm_fc) (if any registered) "prli" function. Likewise when
LOGO request is received, "prlo" function of passive provider is
invoked by libfc.  For all other request (e.g. any read/write, task
management, LUN inquiry commands), "recv" function of passiver
provider is invoked by libfc. Those passive providers "prli, prlo,
recv" functions interact with TCM target core for requested operation.

This module was primarily developed by "Joe Eykholt" and there were
significant contributions from the people listed under signed-off.

e37c4913c5 [SCSI] iterate over devices individually for /proc/scsi/scsi
On systems with very large numbers (> 1600 or so) of SCSI devices,
cat /proc/scsi/scsi ends up failing with -ENOMEM. This is due to
the show routine simply iterating over all of the devices with
bus_for_each_dev(), and trying to dump all of them into the buffer
at the same time. On my test system (using scsi_debug with 4064 devices),
the output ends up being ~ 632k, far more than kmalloc will typically allow.

This patch defines its own seq_file opreations to iterate over the scsi
devices.The result is that each show() operation only dumps ~ 180 bytes
into the buffer at a time so we don't run out of memory.

If the "Attached devices" header isn't required, we can dump the
sfile->private bit completely.

201aed6784 [SCSI] ibmvscsi: Improve CRQ reset reliability
This patch fixes an issue seen where an event occurs
which causes the ibmvscsi driver to reset its CRQ. Upon
re-registering its CRQ, it receives H_CLOSED, indicating
the Virtual I/O Server is not yet ready to receive commands.
This resulted in the ibmvscsi driver essentially offlining
the adapter and not recovering. The fix is to re-enable
our interrupt so that when the Virtual I/O server is ready
and sends a CRQ init, we will be able to receive it and
resume initialization of the VSCSI adapter.

4d4dd70655 [SCSI] ipr: increase the dump size for 64 bit adapters
Currently the size of the dump generated by the driver is limited
in 4MB, which is insufficient to gather much useful data from the
new 64 bit adapters.

This patch makes the needed changes to increase the dump limit
for the 64 bit adapters to 32MB, or even to a bigger value in the
future, but keeping the current limitations for the legacy 32 bit
adapters.

c0d289b3e5 [SCSI] scsi_dh_alua: Attach to UNAVAILABLE/OFFLINE AAS devices
The SCSI ALUA handler currently fails to attach to devices
reporting an UNAVAILABLE/OFFLINE AAS. But given that an
UNAVAILABLE/OFFLINE AAS can transition to other states
like ACTIVE/OPTIMIZED, ACTIVE/NON-OPTIMIZED, etc. as per
SPC4, this ALUA handler behavior should be rectified so
as to attach to devices which also report an
UNAVAILABLE/OFFLINE AAS.
