Number of apqn target list entries contained in 'nr_apqns' variable is
determined by userspace via an ioctl call so the result of the product in
calculation of size passed to memdup_user() may overflow.
In this case the actual size of the allocated area and the value
describing it won't be in sync leading to various types of unpredictable
behaviour later.
Use a proper memdup_array_user() helper which returns an error if an
overflow is detected. Note that it is different from when nr_apqns is
initially zero - that case is considered valid and should be handled in
subsequent pkey_handler implementations.

In the fts_read() function, when handling hwmon_pwm_auto_channels_temp,
the code accesses the shared variable data->fan_source[channel] twice
without holding any locks. It is first checked against
FTS_FAN_SOURCE_INVALID, and if the check passes, it is read again
when used as an argument to the BIT() macro.
This creates a Time-of-Check to Time-of-Use (TOCTOU) race condition.
Another thread executing fts_update_device() can modify the value of
data->fan_source[channel] between the check and its use. If the value
is changed to FTS_FAN_SOURCE_INVALID (0xff) during this window, the
BIT() macro will be called with a large shift value (BIT(255)).
A bit shift by a value greater than or equal to the type width is
undefined behavior and can lead to a crash or incorrect values being
returned to userspace.
Fix this by reading data->fan_source[channel] into a local variable
once, eliminating the race condition. Additionally, add a bounds check
to ensure the value is less than BITS_PER_LONG before passing it to
the BIT() macro, making the code more robust against undefined behavior.
This possible bug was found by an experimental static analysis tool
developed by our team.

Avoid 64-bit integer division that 32-bit architectures don't
implement generally. This uses ktime_to_us() and ktime_to_ms()
instead.
The time abstraction needs i64 / u32 division so C's div_s64() can be
used but ktime_to_us() and ktime_to_ms() provide a simpler solution
for this time abstraction problem on 32-bit architectures.
32-bit ARM is the only 32-bit architecture currently supported by
Rust. Using the cfg attribute, only 32-bit architectures will call
ktime_to_us() and ktime_to_ms(), while the other 64-bit architectures
will continue to use the current code as-is to avoid the overhead.
One downside of calling the C's functions is that the as_micros/millis
methods can no longer be const fn. We stick with the simpler approach
unless there's a compelling need for a const fn.

this saves 16 bytes per control.
Each cs_dsp_coeff_ctl instance needs to keep information about the
algorithm region it refers to. This is done by embedding an instance
of struct cs_dsp_alg_region. But cs_dsp_alg_region was also used to
store entries in a list of algorithm regions, and so had a struct
list_head object for that purpose. This list_head object is not used
with the embedded object in struct cs_dsp_alg_region so was just
wasted bytes.

The datasheets for all the fan53555 variants (and clones using the same
interface) define so called soft start times, from enabling the regulator
until at least some percentage of the output (i.e. 92% for the rk860x
types) are available.
The regulator framework supports this with the enable_time property
but currently the fan53555 driver does not define enable_times for any
variant.
I ran into a problem with this while testing the new driver for the
Rockchip NPUs (rocket), which does runtime-pm including disabling and
enabling a rk8602 as needed. When reenabling the regulator while running
a load, fatal hangs could be observed while enabling the associated
power-domain, which the regulator supplies.
Experimentally setting the regulator to always-on, made the issue
disappear, leading to the missing delay to let power stabilize.
And as expected, setting the enable-time to a non-zero value
according to the datasheet also resolved the regulator-issue.
The datasheets in nearly all cases only specify "typical" values,
except for the fan53555 type 08. There both a typical and maximum
value are listed - 40uS apart.
For all typical values I've added 100uS to be on the safe side.
Individual details for the relevant regulators below:
- fan53526:
The datasheet for all variants lists a typical value of 150uS, so
make that 250uS with safety margin.
- fan53555:
types 08 and 18 (unsupported) are given a typical enable time of 135uS
but also a maximum of 175uS so use that value. All the other types only
have a typical time in the datasheet of 300uS, so give a bit margin by
setting it to 400uS.
- rk8600 + rk8602:
Datasheet reports a typical value of 260us, so use 360uS to be safe.
- syr82x + syr83x:
All datasheets report typical soft-start values of 300uS for these
regulators, so use 400uS.
- tcs452x:
Datasheet sadly does not report a soft-start time, so I've not set
an enable-time

Currently, the DSP core from i.MX8QM/i.MX8QXP is able to operate while the
firmware image is being loaded. Because of this, the DSP may change the
content of the firmware data just after it was loaded, thus leading to the
data having unexpected values when the DSP is reset (via run()).
Fix this by implementing the core_shutdown() operation that will put the
DSP in stall during suspend(). The stall will be removed during the run()
opertion, thus guaranteeing that the DSP core will not be able to run
while the firmware image is being loaded.

Firmware-based thermal temperature control loops may aggressively
throttle performance to prevent temperature overshoots relative to the
defined target temperature. This can negatively impact performance. User
space may prefer to prioritize performance, even if it results in
temperature overshoots with in acceptable range.
For example, user space might tolerate temperature overshoots when the
device is placed on a desk, as opposed to when it's on a lap. To
accommodate such scenarios, an optional attribute is provided to specify
a tolerance level for temperature overshoots while maintaining acceptable
performance.
Attribute:
thermal_tolerance: This attribute ranges from 0 to 7, where 0 represents
the most aggressive control to avoid any temperature overshoots, and 7
represents a more graceful approach, favoring performance even at the
expense of temperature overshoots.
Note: This level may not scale linearly. For example, a value of 3 does not
necessarily imply a 50% improvement in performance compared to a value of 0.

drivers/video/fbdev/sis/sis_main.c: warning: EXPORT_SYMBOL() is used, but #include <linux/export.h> is missing
The affected symbols are not used outside of their module. Some of
the symbols are not used anywhere, so remove the functions entirely.
Also remove the related, but unused, define SISFB_HAVE_MALLOC_NEW.
