Below is the changeset from the MPI specification and 2.00.34 header files
1) Defined additional bits in the BiosOptions field of BIOS Page 1 to allow for finer control of X86 BIOS and UEFI BSD.
2) For the Clean Tool, reserved bit 26 of the Flags field for product specific use.

This patch will log a message when driver receives "Temperature Threshold exceeded" event from any temperature sensor.
The message will look similar to like
mpt3sas0: Temperature Threshold flags a b c d exceeded for Sensor: x !!!
mpt3sas0: Current Temp In Celsius: y
where a b c d are threshold flags 0 1 2 3
Change_set:
1. Get the number of sensor count of this IOC by reading IO Unit page 8 at driver initialization time.
2. Also unmask the Temperature Threshold Event at driver initialization time,
3. Whenever a MPI2_EVENT_TEMP_THRESHOLD event is received from the firmware then print the sensor number, the maximum threshold number it has exceed and the current temperature of this sensor.

When a flaky disk is there in a topology then during driver load,
discovery related I/O times out; which results in SCSI error recovery
initiating host reset and then the controller won't see any disk.
In this patch, The driver would return FAILED status to the host reset
initiated due to discovery related I/O timeout if ioc->is_driver_loading
is set. This flag would be set until we exit out of scsih_scan_finished().
i.e.
During device discovery if one of the disk is flaky
(which responds to some discovery commands and doesn't respond to some)
the driver wouldn't perform host reset for discovery related I/O timeout.
Instead it would return Failure for the host reset resulting in the
flaky disk getting removed by the SCSI Mid layer,
so other disks would be added correctly.

Change Set:
1. Extended the upper boundary restriction for the module parameter max_sgl_entries.
Earlier, the max_sgl_entries was capped at the SCSI_MAX_SG_SEGMENTS kernel definition.
With this change, the user would be able to set the max_sgl_entries to
any value which is greater than SCSI_MAX_SG_SEGMENTS and less than the minimum of
SCSI_MAX_SG_CHAIN_SEGMENTS & hardware limit(Calculated using IOCFacts's MaxChainDepth).
2. Added a print for the message log whenever the user sets the max_sgl_entries to a value
greater than SCSI_MAX_SG_SEGMENTS to warn about the kernel definition overriding.

For any SCSI command, if the driver receives IOC status = SCSI_IOC_TERMINATED and log info = 0x32010081
then that command will be completed with DID_RESET host status.
The definition of this log info value is "Virtual IO has failed and has to be retried".
Firmware will provide this log info value with IOC Status
"SCSI_IOC_TERMINATED", whenever a drive (with is a part of a volume)
is pulled and pushed back within some minimal delay. With this log info
value, firmware informs the driver to retry the failed IO command
infinite times, so to provide some time for the firmware to discover
the reinserted drive successfully instated of just retrying failed
command for five times( doesn't giving enough time for firmware to
complete the drive discovery) and failing the IO permanently even
though drive came back successfully.

Added a support to set cpu affinity mask for each MSIX vector enabled by the HBA.
So that, running the irqbalancer will balance interrupts among the cpus.
Change_set:
1. Added affinity_hint varable of type cpumask_var_t in adapter_reply_queue
structure. And allocated a memory for this varable by calling alloc_cpumask_var.
2. Call the API irq_set_affinity_hint for each MSIx vector to affiniate it
with calculated cpus at driver inilization time.
3. While freeing the MSIX vector, call this same API to release the cpu affinity mask
for each MSIx vector by providing the NULL value in cpumask argument.
4. then call the free_cpumask_var API to free the memory allocated in step 2.
