20f5895d55 [SCSI] mpt2sas: Expander fix oops saying "Already part of another port"
Kernel panic is seen because driver did not tear down the port which should
be dnoe using mpt2sas_transport_port_remove(). without this fix When expander
is added back we would oops inside sas_port_add_phy.

d5d135b3a7 [SCSI] mpt2sas: using the same naming convention for all static function
This fix's is for all local function so their name has the "_" preceeding
the module name, then function name.  Most the code is already is using this
naming convention.

993e0da7b7 [SCSI] mpt2sas: LUN Reset Support
Adding new eh_target_reset_handler for target reset. Change the
eh_device_reset_handler so its sending
MPI2_SCSITASKMGMT_TASKTYPE_LOGICAL_UNIT_RESET, instead of
MPI2_SCSITASKMGMT_TASKTYPE_TARGET_RESET.  Add new function
_scsih_scsi_lookup_find_by_lun as a sanity check to insure I_T_L commands are
completed upon completing lun reset.

6f92a7a0af [SCSI] mpt2sas: fix hotplug event processing
Here's a fix for hotplug events.  The useage of queue_delayed_work seems
to broke the fifo for processing of firmware events.  After several iterations
of adding and removing cabling connected to jbods, the devices are not
getting added becuase kernel thread is activited out of order.

8901cbb45e [SCSI] mpt2sas : Broadcast Primative AEN bug fix
Bug fix in the broadcast primative async event code where the driver would
stop sending tm queries after the first queury was completed. This was due
driver not reseting the tm_cmds.status field back to MPT2_CMD_NOT_USED after
completing a task management request.

An addtional fix adding sanity check to insure sas_device->starget set to NULL.
During multipath testing fail over/fail back, the mid layer was holding onto
sdev longer than the fail back period, thus starget was getting set to NULL
for device being added.

0d04df9b4a [SCSI] mpt2sas : fix oops when firmware sends large sense buffer size
There is a bug in firmware where the reply message frame says there is a
16kb sense buffer, when in reality its only 20 bytes.  This fix insures
the memcpy action doesn't corrupte the memory beyond the 90 bytes allocated in
the scsi command for sense buffer.

ba33fadfab [SCSI] mpt2sas: make global symbols unique
The ioc_list global symbol is already used in 1st generation mpt
fusion drivers, so this patch makes it unique in the 2nd generation
driver.  I've checked the entire sources, and I don't see any other
global system missing the mpt2sas_xxx prefix.
