bc93d425fc [SCSI] megaraid_sas: Add support for Uneven Span PRL11
MegaRAID older Firmware does not support uneven span configuration for PRL11.
E.g User wants to create 34 Driver PRL11 config, it was not possible using old
firmware, since it was not supported configuration in old firmware

Old Firmware expect even number of Drives in each span and same number of
physical drives at each span.  Considering above design, 17 Drives at Span-0
and 17 drives at span-1 was not possible.

Now, using this new feature Firmware and Driver both required changes.  New
Firmware can allow user to create 16 Drives at span-0 and 18 Drives at
span-1. This will allow user to create 34 Drives Uneven span PRL11.

RAID map is interface between Driver and FW to fetch all required
fields(attributes) for each Virtual Drives.  Since legacy RAID map consider
Even Span design, there was no place to keep Uneven span information in
existing Raid map.  Because of this limitation, for Uneven span VD, driver can
not use RAID map.

This patch address the changes required in Driver to support Uneven span PRL11
support.

1. Driver will find if Firmware has UnevenSpanSupport or not by reading
   Controller Info.
2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its
   capability of handling UnevenSpan PRL11 to the firmware.
3. Driver will update its copy of span info on each time Raid map update is
   called.
4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver
   uses Span Set info to find relavent fields for that particular Virtual
   Disk)

More verbose prints will be available by setting "SPAN_DEBUG" to 1 at
compilation time.

111ecbe426 [SCSI] bfa: fix faulty handling of events in lps sm
When a switch disable/enable or a reboot is done, the HBA port gets an
offline and a subsequent online notification. When the port comes up a
link up notification is sent to bfa from the firmware. The bfa then send
an FLOGI to the firmware which is sent out on the wire.
The switch port meanwhile goes offline (presumably for diagnostics)
which causes the switch not to respond to the FLOGI.
The link down notification is sent to the HBA driver. However owing to a
bug in the lps state machine handling the lps state machine does not
move to sm_init state (it remains in sm_login state and send a login
complete message to fcs). This results in a zero PID assignment as the
login is not really complete.

This fix is to correctly handle the events in lps state machine.

0761df9c4b [SCSI] sd: avoid deadlocks when running under multipath
When multipathed systems run into an all-paths-down scenario
all devices might be dropped, too. This causes 'del_gendisk'
to be called, which will unregister the kobj_map->probe()
function for all disk device numbers.
When the device comes back the default ->probe() function
is run which will call __request_module(), which will
deadlock.
As 'del_gendisk' typically does _not_ trigger a module unload
the default ->probe() function is pointless anyway.
This patch implements a dummy ->probe() function, which will
just return NULL if the disk is not registered.
This will avoid the deadlock. Plus it'll speed up device
scanning.

8526cb114f [SCSI] iscsi class, qla4xxx: fix sess/conn refcounting when find fns are used
This fixes a bug where the iscsi class/driver did not do a put_device
when a sess/conn device was found. This also simplifies the interface
by not having to pass in some arguments that were duplicated and did
not need to be exported.

aa9f8328fc [SCSI] sas: unify the pointlessly separated enums sas_dev_type and sas_device_type
These enums have been separate since the dawn of SAS, mainly because the
latter is a procotol only enum and the former includes additional state
for libsas.  The dichotomy causes endless confusion about which one you
should use where and leads to pointless warnings like this:

drivers/scsi/mvsas/mv_sas.c: In function 'mvs_update_phyinfo':
drivers/scsi/mvsas/mv_sas.c:1162:34: warning: comparison between 'enum sas_device_type' and 'enum sas_dev_type' [-Wenum-compare]

Fix by eliminating one of them.  The one kept is effectively the sas.h
one, but call it sas_device_type and make sure the enums are all
properly namespaced with the SAS_ prefix.
