Instead of issuing a standard inquiry from within the
alua device handler we can evaluate the TPGS setting from
the existing inquiry data of the sdev and save us the I/O.Signed-off-by: Hannes Reinecke

->queuecommand must return either 0, or one of the SCSI_MLQUEUE_* return
values. Non-transient errors are indicated by setting cmd->result before
calling ->scsi_done and returning 0. Fix libsas to adhere to this calling
convention. Note that the DID_ERROR for returns from the low-level driver
might not be correct for all cases, but it's the best we can do with
the current layering in libsas. I also suspect that the pre-existing
handling of -SAS_QUEUE_FULL should really be SCSI_MLQUEUE_HOST_BUSY, but
I'll leave that for a separate change.Signed-off-by: Christoph Hellwig

sd_ioctl() still use printk() for log output.
It should use sd_printk() instead of printk(), as well as other sd_*.All SCSI messages should output via s*_printk() instead of printk().

Fix SYSFS interface issues.
- In the lpfc_sli4_pdev_status_reg_wait() routine, after initial 100ms delay
following write to PHYSDEV_CONTROL register for the firmware reaction, check
the RN bit and ERR bit of the SLIPORT_STATUS register. If none of them
became 1, the previous PHYSDEV_CONTROL register should be considered failed
due to lack of privilege and error for no permission should be returned
immediately without getting into the wait for RDY bits on the SLIPORT_STATUS
register.
- Remove the driver check on dev->is_physfn before proceed to perform the
PHYSDEV_CONTROL register write, and let the PCI function's privilege
setting and driver handling of PHYSDEV_CONTROL register write failure to
handle the reset-ability through the SLI port.
- Added key to ctlreg_write to prevent unauthorized or unexpected write to
the control register.
- Change return to EACCES for sysfs access that are failed because hba_reset
is disabled.Signed-off-by: Alex Iannicelli

Fix HBA initialization issues
- Swap all values that come from the firmware image on little endian systems.
Created a new bf_get_be macro that does the same as the bf_get_le macro but
for big endian data instead of little endian data.
- Moved the incrementing of temp_offset after the copy
fixed the write object loop to use temp_offset to figure out where the end
of the image is instead of offset.
- Added the necessary codes for properly bringing the driver instance offline
and then trying to bring the port back online with the PCI function IP reset.
If it fails to bring the SLI port back online, it will fall through to
bringing the SLI port to HBA error offline.
- Add a call in the probe_one_s3 and probe_one_s4 routines to get the Modeldesc
- Change OCe50100 to OCe15100

Fix issues pertaining to SCSI/FC protocol.
- Allow frames destined to 0xFFFFFE to be processed by the driver by matching
that DID with the physical port.
- Call lpfc_sli_issue_iocb with context1 set to ndlp
- In echo command accept function, adjust memcpy to limit memcpy to 1K
- Set LPFC_SLI3_BG_ENABLED properly upon completion.
- Skip the INIT_VFI call in lpfc_register_fcf if the FCF is already
registered and go immediately to initial flogi.
- use "status" variable instead of "ret" variable to hold the return of the
fc_block_scsi_eh.Signed-off-by: Alex Iannicelli

Fix be2iscsi driver to use a separate pointer for each irq action->name
field and avoid display corruption in /proc/interrupts. The be2iscsi driver
was using a single static array in a function for the irq action->name field.
This results in garbage output from /proc/interruptsThe pointer for action->name is garbage and scribbles the output on the screen.

The Marvell Universal Message Interface (UMI) defines a messaging
interface between host and Marvell products (Plato, for example). It
considers situations of limited system resource and optimized system
performance.
UMI driver translates host request to message and sends message
to FW via UMI, FW receives message and processes it, then sends response
to UMI driver.
FW generates an interrupt when it needs to send information or
response to UMI driverSigned-off-by: Jianyun Li

Some CD-ROMs fail to report a media change correctly. The specific
one for this patch simply fails to respond to commands, then gives a
UNIT ATTENTION after being reset which returns ASC/ASCQ 28/00. This
is out of spec behaviour, but add a check in the eat CC/UA on reset
path to catch this case so the CD-ROM will function somewhat properly.[jejb: fixed up white space and accepted without signoff]
