ufshcd_cmd_inflight() is used to check whether or not a command is in
progress. Make it skip commands that have already completed by changing
the !blk_mq_request_started(rq) check into blk_mq_rq_state(rq) !=
MQ_RQ_IN_FLIGHT. We cannot rely on lrbp->cmd since lrbp->cmd is not
cleared when a command completes.

UFS spec version 2.1 was published more than 10 years ago. It is
vanishingly unlikely that even there are out there platforms that uses
earlier host controllers, let alone that those ancient platforms will ever
run a V6.10 kernel. To be extra cautious, leave out removal of UFSHCI 2.0
support from this patch, and just remove support of host controllers prior
to UFS2.0.
This patch removes some legacy tuning calls that no longer apply.

Switch to the ->device_configure method instead of ->slave_configure and
update the block limits on the passed in queue_limits instead of using the
per-limit accessors.
Note that mpi3mr also updates the limits from an event handler that
iterates all SCSI devices. This is also updated to use the queue_limits,
but the complete locking of this path probably means it already is
completely broken and needs a proper audit.

This is a version of ->slave_configure that also takes a queue_limits
structure that the caller applies, and thus allows drivers to reconfigure
the queue using the atomic queue limits API.
In the long run it should also replace ->slave_configure entirely as there
is no need to have two different methods here, and the slave name in
addition to being politically charged also has no basis in the SCSI
standards or the kernel code.

While we really should be killing the block layer bounce buffering ASAP, I
even more urgently need to stop the drivers to fiddle with the limits from
->slave_configure. Add a no_highmem flag to the Scsi_Host to centralize
this setting and switch the remaining four drivers that use block layer
bounce buffering to it.

Some but not all command information is cleared by scsi_end_request().
As an example, if scsi_show_rq() is called after a SCSI command has been
allocated and before SCMD_INITIALIZED is set, .cmnd holds the CDB
of a previous command. Showing that information in debugfs is confusing.
Hence this patch that restricts the information shown in debugfs to
valid information.

Pointer currTar_Info is being assigned a value that is never read, it is
being re-assigned a few lines later in the start of a following do-while
loop. The assignment is redundant and can be removed.

Fix indentation of config option's help text by adding leading spaces.
Generally help text is indented by two more spaces beyond the leading tab
<\t> character. It helps Kconfig parsers to read file without error.

Calling a function through an incompatible pointer type causes breaks kcfi,
so clang warns about the assignments:
drivers/scsi/cxlflash/main.c:3498:3: error: cast from 'int (*)(struct cxlflash_cfg *, struct ht_cxlflash_lun_provision *)' to 'hioctl' (aka 'int (*)(struct cxlflash_cfg *, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
3498 | (hioctl)cxlflash_lun_provision },
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/scsi/cxlflash/main.c:3500:3: error: cast from 'int (*)(struct cxlflash_cfg *, struct ht_cxlflash_afu_debug *)' to 'hioctl' (aka 'int (*)(struct cxlflash_cfg *, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
3500 | (hioctl)cxlflash_afu_debug },
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
Address these by changing the functions to have the correct type and
replace the function pointer cast with a cast of its argument.

Let's add the checks to warn the user if the ICC scaling is not supported
for the gear/lane values and also fallback to the max value if that's the
case.

Uwe Kleine-König <u.kleine-koenig@pengutronix.de> says:
Hello,
this series fixes the same issue in four drivers. The warning is a false
positive and to suppress it the driver structs are marked with
__refdata and a comment is added to describe the (non-trivial)
situation.
Best regards
Uwe

Andrew Halaney <ahalaney@redhat.com> says:
Please review with care as I'm not all that confident in this subject.
UFS has a lot of mb() variants used, most with comments saying "ensure
this takes effect before continuing". mb()'s aren't really the way to
guarantee that, a read back is the best method.
Some of these though I think could go a step further and remove the
mb() variant without a read back. As far as I can tell there's no real
reason to ensure it takes effect in most cases (there's no delay() or
anything afterwards, and eventually another readl()/writel() happens
which is by definition ordered). Some of the patches in this series do
that if I was confident it was safe (or a reviewer pointed out prior
that they thought it was safe to do so).
Thanks in advance for the help,
Andrew
