shutdown call
Driver should not call shutdown call from _scsih_remove otherwise,
The scsi midlayer can be deadlocked when devices are removed from the driver
pci_driver->shutdown handler.

Properly handling of target reset in multi-initiator environment
Clean up in broadcast change handling:
(1) Need to look at the status of each task management request, and retry
the TM when there are failures.
(2) Need quiescence IO so the driver doesn't take on more IO request while
it's in the middle of sending TM request to firmware
(3) Add support to keep track of how many pending broadcast AEN events
are received while the broadcast handling is active, then loop back at
the end of this routine if there were any events received.
Clean up in mpt2sas_scsih_issue_tm routine:
(1) Make sure proper status is returned when host reset fails
(2) Clean up sanity checks near end of routine, insuring all outstanding
IOs were completed.

This feature is to override the default
max_sectors setting at load time, taking max_sectors as an
command line option when loading the driver. The setting is
currently hard-coded in the driver to 8192 sectors (4MB transfers).
If max_sectors is specified at load time, minimum specified
setting will be 64, and the maximum is 8192. The driver will
modify the setting to be on even boundary. If max_sectors is not
specified, the driver will default to 8192.

mpt2sas driver revision q header update:
(1) Modified the descriptions of the LocalAddress bit in the
Flags field of the MPI SGE Format description and the MPI
Simple Element.
(2) Modified Data Location Address Space bits in the Flags field
of the IEEE Chain Element.
(3) Added more detail to the description of the DataLength field
for the SCSI IO Request and Target Assist Request. Removed
restriction on using chained SGLs when using multicast or
bidirectional support.
(4) In Manufacturing Page 7, added ReceptacleID field to
ConnectorInfo, and reworked how the Pinout field is used.
(5) In IO Unit Page 7, added BoardTemperature and
BoardTemperatureUnits fields.
(6) In IOC Page 1, changed CoalescingTimeout to units of
half-microsecond and updated descriptions.
(7) Modified descriptions of SATASlumberTimeout and
SASSlumberTimeout fields in SAS IO Unit Page 5 to indicate
the timers start after partial mode is entered.
(8) Added Extended Manufacturing configuration pages.

Driver was incorrectly using the SLAB_CACHE_DMA flag when creating a cache

- Moved FCS initialization, which internally does the im_port creation
as well as the scsi_host creation before bfa_init.
Once the bfa_init is complete & successful:
- Reset the FCS base port cfg params such as pwwn/nwwn and setup fc host
params - based on the values learned during the ioc getattr request.
- Change needed to support BSG commands even on bfa init failure.
- Model description fixes for Brocade adapters.

- Introduce FC credit recovery.
- Added module parameter to enable/disable credit recovery.
Bug Fixes:
- Removed check for ignoring plogi from initiator in switched fabric mode.
- The ABTS for PLOGI is going out few millisecs earlier due to FW
timer calibration (around 300 miilisecs earlier). So there is a
window if an accept comes during this time HBA would have initiated
an ABORT.
- Added 1 to FC_ELS_TOV for compensating for FW timer.

- Added logic to flush pending mailbox command queue when IOC is disabled.
- Fix to Halt the flash controller during fw initialization - since
when asic blck is programmed flash controller's continuous access
blocks f/w access to flash.
- Added new asic based card types and modified IOC get card model routine.
- Added PLL init fix to do LPU reset every time we do a memory

- Introduced IOC poll mechanism which replaces current interrupt
based FW READY method.
- The timer based poll routine in IOC will query the ioc_fwstate
register to see if there is a state change in FW, and sends the READY event.
- Bug fixes in the new asic PLL initialization.
- Added logic to handle CPE/RME queue interrupts before iocfc config done.
1. Use the queue_process flag to see if iocfc configuration is done
in INTX mode.
2. Split the MSIX handler installation in two - one for IOC intr
handler and the other for cpe/rme queue handler - and delay
assigning queue handlers until iocfc config is done in MSIX mode.

Noticed that when the sysfs interface of the SCSI SES
driver was used to request a fault indication the LED
flashed but the buzzer didn't sound. So it was doing
what REQUEST IDENT (locate) should do.
Changelog:
- fix the setting of REQUEST FAULT for the device slot
and array device slot elements in the enclosure control
diagnostic page
- note the potentially defective code that reads the
FAULT SENSED and FAULT REQUESTED bits from the enclosure
status diagnostic page

Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone
as the physical port and shares the same LUN. This happens due to the fact that
vport destroy and unsolicited ELS are scheduled to run on the same workqueue,
and vport destroy destroys the lport and the unsolicited ELS tries to access
the invalid lport. This patch fixes this issue by maintaining a list of valid
lports and verifying if the lport is valid or not before accessing it.

The failure is as follows:
1. Userspace gets forcewake lock, lock count >=1
2. GPU hang/reset occurs (forcewake bit is reset)
3. count is now incorrect
The failure can only occur when using the forcewake userspace lock.
This has the unfortunate consequence of messing up the driver as well as
userspace, unless userspace closes the debugfs file, the kernel will
never end up waking the GT since the refcount will be > 1.
The solution is to try to recover the correct forcewake state based on
the refcount. There is a period of time where userspace reads/writes may
occur after the reset, before the GT has been forcewaked. The interface
was never designed to be a perfect solution for userspace reads/writes,
and the kernel portion is fixed by this patch.

If a device fails in a way that causes pending request to take a while
to complete, md will not be able to immediately remove it from the
array in remove_and_add_spares.
It will then incorrectly look like a spare device and md will try to
recover it even though it is failed.
This leads to a recovery process starting and instantly aborting over
and over again.
We should check if the device is faulty before considering it to be a
spare. This will avoid trying to start a recovery that cannot
proceed.
This bug was introduced in 2.6.26 so that patch is suitable for any
kernel since then.
