When SCSI-MQ is enabled, the SCSI-MQ layers will do pre-allocation of MQ
resources based on shost values set by the driver. In newer cases of the
driver, which attempts to set nr_hw_queues to the cpu count, the
multipliers become excessive, with a single shost having SCSI-MQ
pre-allocation reaching into the multiple GBytes range. NPIV, which
creates additional shosts, only multiply this overhead. On lower-memory
systems, this can exhaust system memory very quickly, resulting in a system
crash or failures in the driver or elsewhere due to low memory conditions.
After testing several scenarios, the situation can be mitigated by limiting
the value set in shost->nr_hw_queues to 4. Although the shost values were
changed, the driver still had per-cpu hardware queues of its own that
allowed parallelization per-cpu. Testing revealed that even with the
smallish number for nr_hw_queues for SCSI-MQ, performance levels remained
near maximum with the within-driver affiinitization.
A module parameter was created to allow the value set for the nr_hw_queues
to be tunable.

Voltage regulators are optional, so functions must check they exist
before dereferencing.
Note this issue is hidden if CONFIG_REGULATORS is not set, because the
offending code is optimised away.
Notes for stable:
The issue first appears in commit 57d104c153d3 ("ufs: add UFS power
management support") but is inadvertently fixed in commit 60f0187031c0
("scsi: ufs: disable vccq if it's not needed by UFS device") which in
turn was reverted by commit 730679817d83 ("Revert "scsi: ufs: disable vccq
if it's not needed by UFS device""). So fix applies v3.18 to v4.5 and
v5.1+

If HBA initialization fails unexpectedly (exiting via probe_failed:), we
may fail to free vha->gnl.l. So that we don't attempt to double free, set
this pointer to NULL after a free and check for NULL at probe_failed: so we

When a configurations runs with a single cpu (such as a kdump kernel),
which causes the driver to request a single vector, when the driver
subsequently requests an irq affinity mask, the mask comes back null. The
driver currently does nothing in this scenario, which leaves mappings to
hardware queues incomplete and crashes the system.
Fix by recognizing the null mask and assigning the vector to the first cpu
in the system.

In qla2x00_alloc_fcport(), fcport is assigned to NULL in the error
handling code on line 4880:
fcport = NULL;
Then fcport is used on lines 4883-4886:
INIT_WORK(&fcport->del_work, qla24xx_delete_sess_fn);
INIT_WORK(&fcport->reg_work, qla_register_fcport_fn);
INIT_LIST_HEAD(&fcport->gnl_entry);
INIT_LIST_HEAD(&fcport->list);
Thus, possible null-pointer dereferences may occur.
To fix these bugs, qla2x00_alloc_fcport() directly returns NULL
in the error handling code.
These bugs are found by a static analysis tool STCheck written by us.

Although SAS3 & SAS3.5 IT HBA controllers support 64-bit DMA addressing, as
per hardware design, if DMA-able range contains all 64-bits
set (0xFFFFFFFF-FFFFFFFF) then it results in a firmware fault.
E.g. SGE's start address is 0xFFFFFFFF-FFFF000 and data length is 0x1000
bytes. when HBA tries to DMA the data at 0xFFFFFFFF-FFFFFFFF location then
HBA will fault the firmware.
Driver will set 63-bit DMA mask to ensure the above address will not be
used.

Gcc-9 complains for a memset across pointer boundaries, which happens as
the code tries to allocate a flexible array on the stack. Turns out we
cannot do this without relying on gcc-isms, so with this patch we'll embed
the fc_rport_priv structure into fcoe_rport, can use the normal
'container_of' outcast, and will only have to do a memset over one
structure.

We should only call dma_max_mapping_size for devices that have a DMA mask
set, otherwise we can run into a NULL pointer dereference that will crash
the system.
Also we need to do right shift to get the sectors from the size in bytes,
not a left shift.

We get a warning when CONFIG_SCSI_LOWLEVEL is disabled here:
WARNING: unmet direct dependencies detected for SCSI_FDOMAIN
Depends on [n]: SCSI_LOWLEVEL [=n] && SCSI [=y]
Selected by [m]:
- PCMCIA_FDOMAIN [=m] && SCSI_LOWLEVEL_PCMCIA [=y] && SCSI [=y] && PCMCIA [=y] && m && MODULES [=y]
Move all of SCSI_LOWLEVEL_PCMCIA inside of the existing SCSI_LOWLEVEL
section. Very few people use the PCMCIA support these days, and they likely
don't mind having to turn on SCSI_LOWLEVEL as well. This way we avoid the
link error and get a more sensible structure.

Pull SCSI fixes from James Bottomley:
"This is the final round of mostly small fixes in our initial submit.
It's mostly minor fixes and driver updates. The only change of note is
adding a virt_boundary_mask to the SCSI host and host template to
parametrise this for NVMe devices instead of having them do a call in
slave_alloc. It's a fairly straightforward conversion except in the
two NVMe handling drivers that didn't set it who now have a virtual
infinity parameter added"

When using a virt_boundary_mask, as done for NVMe devices attached to
megaraid_sas controllers, we require an unlimited max_segment_size as the
virt boundary merging code assumes that. But we also need to propagate
that to the DMA mapping layer to make dma-debug happy. The SCSI layer
takes care of that when using the per-host virt_boundary setting, but
given that megaraid_sas only wants to set the virt_boundary for actual
NVMe devices, we can't rely on that. The DMA layer maximum segment is
global to the HBA however, so we have to set it explicitly. This patch
assumes that megaraid_sas does not have a segment size limitation, which
seems true based on the SGL format, but will need to be verified.

When scsi_init_sense_cache(host) is called concurrently from different
hosts, each code path may find that no cache has been created and
allocate a new one. The lack of locking can lead to potentially
overriding a cache allocated by a different host.
Fix the issue by moving 'mutex_lock(&scsi_sense_cache_mutex)' before
scsi_select_sense_cache().
