Most of these sizes and counts are capped at 256MB so the math doesn't
result in an integer overflow. The "relocs" count needs to be checked
as well. Otherwise on 32bit systems the calculation of "full_data"
could be wrong.
full_data = data_len + relocs * sizeof(unsigned long);

In the SPI-NAND layer, we currently make list of operation variants from
the fastest one to the slowest and there is a bit of logic in the core
to go over them and pick the first one that is supported by the
controller, ie. the fastest one among the supported ops.
This kind of logic only works if all operations run at the same
frequency, but as soon as we introduce per operation max frequencies it
is not longer as obvious which operation will be faster, especially
since it also depends on the PCB/controller frequency limitation.
One way to make this choice more clever is to go over all the
variants and for each of them derive an indicator which will help derive
the theoretical best. In this case, we derive a theoretical duration for
the entire operation and we take the smallest one.
Add a helper that parses the spi-mem operation and returns this value.

The commit "HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd Fn keys"
introduced an issue where the CI failed with the following error:
ERROR: modpost: "platform_profile_cycle" [drivers/hid/hid-lenovo.ko] undefined!
This issue occurs because platform_profile_cycle is used without ensuring
the kernel is configured with CONFIG_ACPI_PLATFORM_PROFILE.
To address this, this patch adds conditional support for platform profile
management to the Fn+F8 key handling.
The functionality for platform_profile_cycle is now included only when
CONFIG_ACPI_PLATFORM_PROFILE is enabled in the kernel configuration.
This ensures compatibility with kernels that do not include the ACPI
platform profile feature, resolving the CI build issue.

nvme multipath reports that they see spurious -EAGAIN bubbling back to
userspace, which is caused by how they handle retries internally through
a kworker. However, any data that needs preserving or importing for

Rather than try and have io_read/io_write turn REQ_F_REISSUE into
-EAGAIN, catch the REQ_F_REISSUE when the request is otherwise
considered as done. This is saner as we know this isn't happening
during an actual submission, and it removes the need to randomly
check REQ_F_REISSUE after read/write submission.
If REQ_F_REISSUE is set, __io_submit_flush_completions() will skip over
this request in terms of posting a CQE, and the regular request
cleaning will ensure that it gets reissued via io-wq.

FEAT_SPEv1p2 (optional from Armv8.6) adds a discard mode that allows all
SPE data to be discarded rather than written to memory. Add a format
bit for this mode.
If the mode isn't supported, the format bit isn't published and attempts
to use it will result in -EOPNOTSUPP. Allocating an aux buffer is still
allowed even though it won't be written to so that old tools continue to
work, but updated tools can choose to skip this step.

queue_attr_store() always freezes a device queue before calling the
attribute store operation. For attributes that control queue limits, the
store operation will also lock the queue limits with a call to
queue_limits_start_update(). However, some drivers (e.g. SCSI sd) may
need to issue commands to a device to obtain limit values from the
hardware with the queue limits locked. This creates a potential ABBA
deadlock situation if a user attempts to modify a limit (thus freezing
the device queue) while the device driver starts a revalidation of the
device queue limits.
Avoid such deadlock by not freezing the queue before calling the
->store_limit() method in struct queue_sysfs_entry and instead use the
queue_limits_commit_update_frozen helper to freeze the queue after taking
the limits lock.
This also removes taking the sysfs lock for the store_limit method as
it doesn't protect anything here, but creates even more nesting.
Hopefully it will go away from the actual sysfs methods entirely soon.

When __blk_mq_update_nr_hw_queues changes the number of tag sets, it
might have to disable poll queues. Currently it does so by adjusting
the BLK_FEAT_POLL, which is a bit against the intent of features that
describe hardware / driver capabilities, but more importantly causes
nasty lock order problems with the broadly held freeze when updating the
number of hardware queues and the limits lock. Fix this by leaving
BLK_FEAT_POLL alone, and instead check for the number of poll queues in
the bio submission and poll handlers. While this adds extra work to the
fast path, the variables are in cache lines used by these operations
anyway, so it should be cheap enough.

(1) Create an /afs/.<cell> mountpoint to match the /afs/<cell> mountpoint
when a cell is created.
(2) Add some more checks on cell names proposed by the user to prevent
dodgy symlink bodies from being created. Also prevent rootcell from
being altered once set to simplify the locking.
(3) Change the handling of /afs/@cell from being a dentry name
substitution at lookup time to making it a symlink to the current cell
name and also provide a /afs/.@cell symlink to point to the dotted
cell mountpoint.

Make /afs/@cell a symlink in the /afs dynamic root to match what other AFS
clients do rather than doing a substitution in the dentry name. This has
the bonus of being tab-expandable also.
Further, provide a /afs/.@cell symlink to point to the dotted cell share.

Add some checks for the validity of the cell name. It's may get put into a
symlink, so preclude it containing any slashes or "..". Also disallow
starting/ending with a dot. This makes /afs/@cell/ as a symlink less of a
security risk.
Also disallow multiple setting of /proc/net/afs/rootcell for any given
network namespace. Once set, the value may not be changed. This makes it
easier to only create /afs/@cell and /afs/.@cell if there's a rootcell.

When a cell is instantiated, automatically create an /afs/.<cell>

drivers/perf/ contains drivers for the perf subsystem, so it makes sense
that the perf list, linux-perf-users@vger.kernel.org, should be
included for perf drivers.

THe last use of il_get_single_channel_number() was removed in 2011 by

when it was still called iwl_legacy_get_single_channel_number.
Remove it.
