When SME is enabled, the smartpqi driver won't work on the HP DL385 G10
machine, which causes the failure of kernel boot because it fails to
allocate pqi error buffer. Please refer to the kernel log:

Basically, the fact that the coherent DMA mask value wasn't set caused the
driver to fall back to SWIOTLB when SME is active.
For correct operation, lets call the dma_set_mask_and_coherent() to
properly set the mask for both streaming and coherent, in order to inform
the kernel about the devices DMA addressing capabilities.

When a HARDWARE_ERROR is triggered for ASC=0x3e, the existing code is only
considering the case where ASCQ=0x1.
According to the http://www.t10.org/lists/asc-num.htm#ASC_3E specification,
other values may occur like a timeout (ASCQ=0x2).
This patch prints an error message when a non-handled message is received.
This can help diagnose a possible misbehavior of the controller or a
missing implementation in the Linux kernel.
This patch keeps the exact same error handling but prints a message if an
ASCQ != 1 is reported.

Clang warns several times in the scsi subsystem (trimmed for brevity):
drivers/scsi/hpsa.c:6209:7: warning: overflow converting case value to
switch condition type (2147762695 to 18446744071562347015) [-Wswitch]

drivers/scsi/hpsa.c:6208:7: warning: overflow converting case value to
switch condition type (2147762694 to 18446744071562347014) [-Wswitch]
case CCISS_GETHEARTBEAT:
^
The root cause is that the _IOC macro can generate really large numbers,
which don't fit into type 'int', which is used for the cmd parameter in
the ioctls in scsi_host_template. My research into how GCC and Clang are
handling this at a low level didn't prove fruitful. However, looking at
the rest of the kernel tree, all ioctls use an 'unsigned int' for the
cmd parameter, which will fit all of the _IOC values in the scsi/ata
subsystems.
Make that change because none of the ioctls expect a negative value for
any command, it brings the ioctls inline with the reset of the kernel,
and it removes ambiguity, which is never good when dealing with compilers.

This is mostly update of the usual drivers: smarpqi, lpfc, qedi,
megaraid_sas, libsas, zfcp, mpt3sas, hisi_sas. Additionally, we have
a pile of annotation, unused variable and minor updates. The big API
change is the updates for Christoph's DMA rework which include
removing the DISABLE_CLUSTERING flag. And finally there are a couple
of target tree updates.

- Driver will free up the resources.
- Driver calls SIS/PQI initialization and rescans the device list.

Problem:
The Linux kernel takes a logical volume offline after a LUN reset. This is
generally accompanied by this message in the dmesg output:
Device offlined - not ready after error recovery
Root Cause:
The root cause is a "quirk" in the timeout handling in the Linux SCSI
layer. The Linux kernel places a 30-second timeout on most media access
commands (reads and writes) that it send to device drivers. When a media
access command times out, the Linux kernel goes into error recovery mode
for the LUN that was the target of the command that timed out. Every
command that timed out is kept on a list inside of the Linux kernel to be
retried later. The kernel attempts to recover the command(s) that timed out
by issuing a LUN reset followed by a TEST UNIT READY. If the LUN reset and
TEST UNIT READY commands are successful, the kernel retries the command(s)
that timed out.
Each SCSI command issued by the kernel has a result field associated with
it. This field indicates the final result of the command (success or
error). When a command times out, the kernel places a value in this result
field indicating that the command timed out.
The "quirk" is that after the LUN reset and TEST UNIT READY commands are
completed, the kernel checks each command on the timed-out command list
before retrying it. If the result field is still "timed out", the kernel
treats that command as not having been successfully recovered for a
retry. If the number of commands that are in this state are greater than
two, the kernel takes the LUN offline.
Fix:
When our RAIDStack receives a LUN reset, it simply waits until all
outstanding commands complete. Generally, all of these outstanding commands
complete successfully. Therefore, the fix in the smartpqi driver is to
always set the command result field to indicate success when a request
completes successfully. This normally isn’t necessary because the result
field is always initialized to success when the command is submitted to the
driver. So when the command completes successfully, the result field is
left untouched. But in this case, the kernel changes the result field
behind the driver’s back and then expects the field to be changed by the
driver as the commands that timed-out complete.

- fix race condition when a unit is deleted after an RLL,
and before we have gotten the LV_STATUS page of the unit.
- In this case we will get a standard inquiry, rather than
the desired page. This will result in a unit presented
which no longer exists.
- If we ask for LV_STATUS, insure we get LV_STATUS
