Remove them and while we're at it, simplify the NULL checks as '!var' is
used more than 'var == NULL'.

506f7f6b26 scsi: mpt3sas: Remove KERN_WARNING from panic uses
Remove the logging level as panic calls stop the machine and should always be
emitted regardless of requested logging level.

These existing panic uses are perhaps inappropriate.

o Coalesce formats and convert MPT3SAS_FMT to "%s: " to improve clarity

919d8a3f3f scsi: mpt3sas: Convert uses of pr_<level> with MPT3SAS_FMT to ioc_<level>
Use a more common logging style.

Done using the perl script below and some typing

$ git grep --name-only -w MPT3SAS_FMT -- "*.c" | \
  xargs perl -i -e 'local $/; while (<>) { s/\bpr_(info|err|notice|warn)\s*\(\s*MPT3SAS_FMT\s*("[^"]+"(?:\s*\\?\s*"[^"]+"\s*){0,5}\s*),\s*ioc->name\s*/ioc_\1(ioc, \2/g; print;}'

Miscellanea for these conversions:

o Coalesce formats
o Realign arguments
o Remove unnecessary parentheses
o Use casts to u64 instead of unsigned long long where appropriate
o Convert broken pr_info uses to pr_cont
o Fix broken format string concatenation with line continuations and
  excess whitespace

72f02ba66b SCSI misc on 20180815
This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx,
 hisi_sas, smartpqi, megaraid_sas, arcmsr.  In addition, with the
 continuing absence of Nic we have target updates for tcmu and target
 core (all with reviews and acks).  The biggest observable change is
 going to be that we're (again) trying to switch to mulitqueue as the
 default (a user can still override the setting on the kernel command
 line).  Other major core stuff is the removal of the remaining
 Microchannel drivers, an update of the internal timers and some
 reworks of completion and result handling.

As a part of host reset operation, driver will flushout all IOs outstanding
at driver level with "DID_RESET" result.  To find which are all commands
outstanding at the driver level, driver loops with smid starting from one
to HBA queue depth and calls mpt3sas_scsih_scsi_lookup_get() to get scmd as
shown below

 for (smid = 1; smid <= ioc->scsiio_depth; smid++) {
                scmd = mpt3sas_scsih_scsi_lookup_get(ioc, smid);
                if (!scmd)
                        continue;

But in mpt3sas_scsih_scsi_lookup_get() function, driver returns some scsi
cmnds which are not outstanding at the driver level (possibly request is
constructed at block layer since QUEUE_FLAG_QUIESCED is not set. Even if
driver uses scsi_block_requests and scsi_unblock_requests, issue still
persists as they will be just blocking further IO from scsi layer and not
from block layer) and these commands are flushed with DID_RESET host bytes
thus resulting into above kernel BUG.

This issue got introduced by commit dbec4c9040 ("scsi: mpt3sas: lockless
command submission").

To fix this issue, we have modified the mpt3sas_scsih_scsi_lookup_get() to
check for smid equals to zero (note: whenever any scsi cmnd is processing
at the driver level then smid for that scsi cmnd will be non-zero, always
it starts from one) before it returns the scmd pointer to the caller. If
smid is zero then this function returns scmd pointer as NULL and driver
won't flushout those scsi cmnds at driver level with DID_RESET host byte
thus this issue will not be observed.

09c2f95ad4 scsi: mpt3sas: Swap I/O memory read value back to cpu endianness
Swap the I/O memory read value back to cpu endianness before storing it in
a data structures which are defined in the MPI headers where u8 components
are not defined in the endianness order.

In this area from day one mpt3sas driver is using le32_to_cpu() &
cpu_to_le32() APIs. But in commit cf6bf9710c
(mpt3sas: Bug fix for big endian systems) we have removed these APIs
before reading I/O memory which we should haven't done it. So
in this patch I am correcting it by adding these APIs back
before accessing I/O memory.

Linux driver when receives Broadcast Asynchronous Event Notification (BAEN)
from the controller firmware, checks all pending I/Os at the driver level
and issues query task, abort task TMs. This is done in the driver to handle
drives which are connected with multiple initiators and undergoing target
resets. In the BAEN handling code, the I/Os issued to NVMe drives are also
handled and query task and abort task TMs are issued, which are not
necessary as there is no multi-initiator and no BAEN concept with NVMe
drives. Hence when the driver checks for pending I/Os it skips NVMe drives
at this moment.

For every IO, memory of PAGE size is allocated for handling NVMe native
PRPS. And in addition to that for every IO (chains need per IO * chain
buffer size, e.g. 38 * 128byte) amount of memory is allocated for chain
buffers.

However, at any point of time; the IO request can be for NVMe target
device (where PRP's page is used for framing PRP's) or can be for SCSI
target device (where chain buffers are used for framing chain
SGE's). This patch modifies the driver to reuse same pre-allocated PRP
page buffers as a chain buffer for IO's targeted for SCSI target
devices. No need to allocate separate buffers for chain SGE's buffers.

Suppose if the number of chain buffers need for IO doesn't fit in the
PRP Page size then driver maintain's separate buffers for those extra
chain buffers that exceeds the PRP page size. For example consider PRP
page size as 4K and chain buffer size as 128 bytes, then number of chain
buffers that can fit in PRP page is 4096/128 => 32. if the number of
chain buffer need per IO exceeds 32; for example consider number of
chains need per IO is 36 then for remaining 4 chain buffer's driver
allocates them individual.

Instead of allocating RDPQ array (This stores the address's of each RDPQ
pools) at run time, now it will be allocated once during driver load
time and same will be reused during host reset operation also (instead
of allocating & freeing this buffer on the fly during every host reset
operation) and then freed during driver unload.

052c220da3 SCSI for-linus on 20180404
This is mostly updates of the usual drivers: arcmsr, qla2xx, lpfc,
 ufs, mpt3sas, hisi_sas.  In addition we have removed several really
 old drivers: sym53c416, NCR53c406a, fdomain, fdomain_cs and removed
 the old scsi_module.c initialization from all remaining drivers.  Plus
 an assortment of bug fixes, initialization errors and other minor
 fixes.
