Sometimes when the card is restarted it may cause -
"irq 16: nobody cared (try booting with the "irqpoll" option)"
that is likely caused so, that the card, after the hard reset
finishes, pulls on the irq. Disabling the ints before or after
the hpsa_kdump_hard_reset_controller fixes it.
At this point we can't know in which state the card is,
so using SA5_INTR_OFF + SA5_REPLY_INTR_MASK_OFFSET defines directly,
instead of the function the drivers provides, seems to be apropriate.

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.

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.

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.

timeouts at driver load time
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.

3. Whenever a MPI2_EVENT_TEMP_THRESHOLD event is received from the
firmware, then print the sensor number, the maximum threshold number it

This patch will address the issue of SCSI device created at OS level for
non existing VD. ldTgtIdtoLd[] array has size 256 for Extended VD firmware
and 128 for legacy firmware. Accessing indices beyond array size (OS will
send TUR, INQUIRY.. commands upto device index 255), may return valid LD
value and that particular SCSI command will be SUCCESS and creating SCSI
device for non existing target(VD).
For legacy firmware (64 VD firmware), invalidates LD (by setting LD value
to 0xff) in LdTgtIdtoLd[] array for device index beyond 127, so that
invalid LD(0xff) value should be returned beyond device index beyond 127.

The only way a guest can identify the removed LUN is when an I/O is
attempted on a removed LUN - the SRB status code indicates that the LUN

Rather than waiting for an I/O to remove the device, force the discovery of
