This driver maintains a version number which is cross-referenced in the
documentation (e.g. to indicate when features are added or changed) and
exposed through the responses to various SCSI commands. For example the
version number is use as the Product Revision number in standard SCSI
INQUIRY responses issued by this driver. The version date string is placed
in a vendor specific area in each standard SCSI INQUIRY response. This
patch bumps both.
Update the driver documentation URL that appears at the top of the driver
source file.

This patch simplifies, or at least makes more consistent, the way setting
the every_nth parameter injects errors. Here is a list of 'opts' flags and
in which cases they inject errors when abs(every_nth)%command_count == 0 is
reached:
- OPT_RECOVERED_ERR: issued on READ(*)s, WRITE(*)s and
WRITE_SCATTEREDs
- OPT_DIF_ERR: issued on READ(*)s, WRITE(*)s and
WRITE_SCATTEREDs
- OPT_DIX_ERR: issued on READ(*)s, WRITE(*)s and
WRITE_SCATTEREDs
- OPT_SHORT_TRANSFER: issued on READ(*)s
- OPT_TRANSPORT_ERR: issued on all commands
- OPT_CMD_ABORT: issued on all commands
The other uses of every_nth were not modified.
Previously if, for example, OPT_SHORT_TRANSFER was armed then if
(abs(every_nth) % command_count == 0) occurred during a command that was
_not_ a READ, then no error injection occurred. This behaviour puzzled
several testers. Now a global "inject_pending" flag is set and the _next_
READ will get hit and that flag is cleared. OPT_RECOVERED_ERR, OPT_DIF_ERR
and OPT_DIX_ERR have similar behaviour. A downside of this is that there
might be a hang-over pending injection that gets triggered by a following
test.
Also expand the every_nth runtime parameter so that it can take hex value
(i.e. with a leading '0x') as well as a decimal value. Now both the 'opts'
and the 'every_nth' runtime parameters can take hexadecimal values.

Many SCSI HBAs support a hostwide tagset, whereby each command submitted to
the HW from all submission queues must have a unique tag identifier.
Normally this unique tag will be in the range [0, max queue], where "max
queue" is the depth of each of the submission queues.
Add support for this hostwide tag feature, via module parameter
"host_max_queue". A non-zero value means that the feature is enabled. In
this case, the submission queues are not exposed to upper layer, i.e. from
blk-mq prespective, the device has a single hw queue. There are 2 reasons
for this:
a. It is assumed that the host can support nr_hw_queues * can_queue
commands, but this is not true for hostwide tags
b. For nr_hw_queues != 0, the request tag is not unique over all HW
queues, and some HBA drivers want to use this tag for the hostwide tag
However, like many SCSI HBA drivers today - megaraid sas being an example -
the full set of HW submission queues are still used in the LLDD driver. So
instead of using a complicated "reply_map" to create a per-CPU submission
queue mapping like megaraid_sas (as it depends on a PCI device + MSIs) -
use a simple algorithm:
hwq = cpu % queue count
If the host_max_queue param is set non-zero, then the max queue depth is
fixed at this value also.
If and when hostwide shared tags are supported in blk-mq/scsi mid-layer,
then the policy to set nr_hw_queues = 0 for hostwide tags can be revised.

Add inline encryption support to ufs-mediatek.
The standards-compliant parts, such as querying the crypto capabilities and
enabling crypto for individual UFS requests, are already handled by
ufshcd-crypto.c, which itself is wired into the blk-crypto framework.
However MediaTek UFS host requires a vendor-specific hce_enable operation
to allow crypto-related registers being accessed normally in kernel. After
this step, MediaTek UFS host can work as standard-compliant host for
inline-encryption related functions.

In the zoned storage model, the sectors within a zone are typically all
writeable. With the introduction of the Zoned Namespace (ZNS) Command
Set in the NVM Express organization, the model was extended to have a
specific writeable capacity.
Extend the zone descriptor data structure with a zone capacity field to
indicate to the user how many sectors in a zone are writeable.
Introduce backward compatibility in the zone report ioctl by extending
the zone report header data structure with a flags field to indicate if
the capacity field is available.

The expression start_idx - dbg_cnt is evaluated using unsigned int
arthithmetic (since these variables are unsigned ints) and hence can never
be less than zero, so the less than comparison is never true. Rewrite the
expression to check for start_idx being less than dbg_cnt.
After the logic was corrected, temp_idx wasn't working correctly. So fix it
as well.

Addresses-Coverity: ("Unsigned compared against 0")
With certain platforms its possible pci_alloc_irq_vectors() may affinitize
irq vectors to multiple (all?) CPUs. The driver is currently assuming
exclusivity and vectors being doled out to different CPUs and is assigning
primary ownership of each vector to the first CPU in the mask. The code
doesn't bother to check if the CPU already owns a vector and will
unconditionally overwrite the CPU to vector mapping. This causes the
relationships between eq's and cq's to get confused and gets worse when
CPUs start to offline. The net results are interrupts are skipped resulting
in mailbox timeouts and there are oopses in CPU offling flows.
Fix this changing up the primary vector assignment. Now assign the eq to a
CPU only if it is the CPU in the mask that does not have a prior
assignment. And once the primary ownership is assigned, break from the
loop. For CPUs that may have been set before but not the primary owner, the
lpfc_cpu_affinity_check() routine will balance the CPU to eq assignment.

Introduce functions to manipulate UFS inline encryption hardware in line
with the JEDEC UFSHCI v2.1 specification and to work with the block keyslot
manager.
The UFS crypto API will assume by default that a vendor driver doesn't
support UFS crypto, even if the hardware advertises the capability, because
a lot of hardware requires some special handling that's not specified in
the aforementioned JEDEC spec. Each vendor driver must explicitly set
hba->caps |= UFSHCD_CAP_CRYPTO before ufshcd_hba_init_crypto_capabilities()
is called to opt-in to UFS crypto support.
