While struct_size() is normally used in situations where the structure
type already has a pointer instance, there are places where no variable
is available. In the past, this has been worked around by using a typed
NULL first argument, but this is a bit ugly. Add a helper to do this,
and replace the handful of instances of the code pattern with it.
Instances were found with this Coccinelle script:
@struct_size_t@
identifier STRUCT, MEMBER;
expression COUNT;
@@
- struct_size((struct STRUCT *)\(0\|NULL\),
+ struct_size_t(struct STRUCT,
MEMBER, COUNT)

In the ongoing effort to replace all fake flexible arrays with true
flexible arrays, replace the sge32, sge64, and sge_skinny members of union
megasas_sgl with true flexible arrays. No binary differences are seen after
this change; sizes were already being manually calculated using the member
struct sizes directly.

In kdump kernel mode, the driver works in reduced functionality mode with
some features disabled such as reduced MSI-X count and RDPQ disabled, etc.
However, the firmware is not aware of this mode in some cases, which
results in undefined behavior.
To address this, the driver informs the firmware about the kdump mode
through MPI capabilities bit during driver initialization. This allows
firmware to adjust its behavior accordingly.

The firmware only supports Logical Disk IDs up to 240 and LD ID 255 (0xFF)
is reserved for deleted LDs. However, in some cases, firmware was assigning
LD ID 254 (0xFE) to deleted LDs and this was causing the driver to mark the
wrong disk as deleted. This in turn caused the wrong disk device to be
taken offline by the SCSI midlayer.
To address this issue, limit the LD ID range from 255 to 240. This ensures
the deleted LD ID is properly identified and removed by the driver without
accidently deleting any valid LDs.

Commit 6600593cbd ("block: rename BLK_EH_NOT_HANDLED to BLK_EH_DONE")
made it impossible for .eh_timed_out() implementations to call
scsi_done() without causing a crash.
Restore support for SCSI timeout handlers to call scsi_done() as follows:
* Change all .eh_timed_out() handlers as follows:
- Change the return type into enum scsi_timeout_action.
- Change BLK_EH_RESET_TIMER into SCSI_EH_RESET_TIMER.
- Change BLK_EH_DONE into SCSI_EH_NOT_HANDLED.
* In scsi_timeout(), convert the SCSI_EH_* values into BLK_EH_* values.

Updates to the usual drivers (ufs, qla2xx, target, lpfc, smartpqi,
mpi3mr). The main driver change that might cause issues on down the
road is the conversion of some of our oldest surviving drivers to the
DMA API (should only affect m68k). The only major core change is the
rework of async resume; the rest are either completely trivial or for

The megaraid SCSI driver sets set->nr_maps as 3 if poll_queues is > 0, and
blk-mq actually initializes each map's nr_queues as nr_hw_queues.
Consequently the driver has to clear READ queue map's nr_queues, otherwise
the queue map becomes broken if poll_queues is set as non-zero.

The megaraid_sas driver supports single LUN for RAID devices. That is LUN
0. All other LUNs are unsupported. When a device scan on a logical target
with invalid LUN number is invoked through sysfs, that target ends up
getting removed.
Add LUN ID validation in the slave destroy function to avoid the target
deletion.

The driver uses irq_set_affinity_hint() specifically for the high IOPS
queue interrupts for two purposes:
- To set the affinity_hint which is consumed by the userspace for
distributing the interrupts
- To apply an affinity that it provides
The driver enforces its own affinity to bind the high IOPS queue interrupts
to the local NUMA node. However, irq_set_affinity_hint() applying the
provided cpumask as an affinity for the interrupt is an undocumented side
effect.
To remove this side effect irq_set_affinity_hint() has been marked
as deprecated and new interfaces have been introduced. Hence, replace the
irq_set_affinity_hint() with the new interface irq_set_affinity_and_hint()
where the provided mask needs to be applied as the affinity and
affinity_hint pointer needs to be set and replace with
irq_update_affinity_hint() where only affinity_hint needs to be updated.
Change the megasas_set_high_iops_queue_affinity_hint function name to
megasas_set_high_iops_queue_affinity_and_hint to clearly indicate that the
function is setting both affinity and affinity_hint.
