In commit 9b725a90a8f1 ("powerpc/64s: Disallow PROT_SAO in LPARs by
default") PROT_SAO was disabled in guests/LPARs by default. So skip
the test if we are running in a guest to avoid a spurious failure.

The recent commit 7d8196641ee1 ("regulator: Remove pointer table
overallocation") changed the size of coupled_rdevs and now KASAN is able
to detect slab-out-of-bounds problem in regulator_unlock_recursive(),
which is a legit problem caused by a typo in the code. The recursive
unlock function uses n_coupled value of a parent regulator for unlocking
supply regulator, while supply's n_coupled should be used. In practice
problem may only affect platforms that use coupled regulators.

When the wm8958_mic_detect, wm8994_mic_detect functions get called from
the machine driver, e.g. from the card's late_probe() callback, the CODEC
device may be PM runtime suspended and any regmap writes have no effect.
Add PM runtime calls to these functions to ensure the device registers
are updated as expected.
This suppresses an error during boot
"wm8994-codec: ASoC: error at snd_soc_component_update_bits on wm8994-codec"
caused by the regmap access error due to the cache_only flag being set.

According to the user's manual chapter 8.2.1 of Loongson 3A2000 CPU [1]
and 3A3000 CPU [2], we should take some event IDs such as 274, 358, 359
and 360 as valid in the check condition, otherwise they are recognized
as "not supported", fix it.

When calling into hid_map_usage(), the passed event code is
blindly stored as is, even if it doesn't fit in the associated bitmap.
This event code can come from a variety of sources, including devices
masquerading as input devices, only a bit more "programmable".
Instead of taking the event code at face value, check that it actually
fits the corresponding bitmap, and if it doesn't:
- spit out a warning so that we know which device is acting up
- NULLify the bitmap pointer so that we catch unexpected uses
Code paths that can make use of untrusted inputs can now check
that the mapping was indeed correct and bail out if not.

It appears that a ReportSize value of zero is legal, even if a bit
non-sensical. Most of the HID code seems to handle that gracefully,
except when computing the total size in bytes. When fed as input to
memset, this leads to some funky outcomes.
Detect the corner case and correctly compute the size.

The driver is unable to successfully login with remote device. During pt2pt
login, the driver completes its FLOGI request with the remote device having
WWN precedence. The remote device issues its own (delayed) FLOGI after
accepting the driver's and, upon transmitting the FLOGI, immediately
recognizes it has already processed the driver's FLOGI thus it transitions
to sending a PLOGI before waiting for an ACC to its FLOGI.
In the driver, the FLOGI is received and an ACC sent, followed by the PLOGI
being received and an ACC sent. The issue is that the PLOGI reception
occurs before the response from the adapter from the FLOGI ACC is
received. Processing of the PLOGI sets state flags to perform the REG_RPI
mailbox command and proceed with the rest of discovery on the port. The
same completion routine used by both FLOGI and PLOGI is generic in
nature. One of the things it does is clear flags, and those flags happen to
drive the rest of discovery. So what happened was the PLOGI processing set
the flags, the FLOGI ACC completion cleared them, thus when the PLOGI ACC
completes it doesn't see the flags and stops.
Fix by modifying the generic completion routine to not clear the rest of
discovery flag (NLP_ACC_REGLOGIN) unless the completion is also associated
with performing a mailbox command as part of its handling. For things such
as FLOGI ACC, there isn't a subsequent action to perform with the adapter,
thus there is no mailbox cmd ptr. PLOGI ACC though will perform REG_RPI
upon completion, thus there is a mailbox cmd ptr.

It's writing too much data. regmap_bulk_write expects number of
register sized chunks to write, not a byte sized length of the
bounce buffer. Bounce buffer needs to be padded too, so that
regmap_bulk_write will not read past the end of the buffer.

While reviewing a separate patch, I noticed that the formatting of the
commands, variables, and arguments was not in a monospaced font like the
rest of the Kbuild documentation (see kbuild/kconfig.rst for an
example). This is due to a lack of "::" before indented command blocks
and single backticks instead of double backticks for inline formatting.
Add those so that the document looks nicer in an HTML format, while not
ruining the look in plain text.
As a result of this, we can remove the escaped backslashes in the last
code block and move them to single backslashes.

First set of IIO fixes for the 5.9 cycle
Most of the fixes this time are for a long term issue that Lars-Peter
Clausen identified recently.
IIO assumes that any data pushed to the buffer interface (either kfifo
or another in kernel consumer) are naturally aligned. Unfortunately
this isn't true in a number of drivers, mostly by failing to ensure
the buffer used is aligned suitably for an s64 timestamp.
For the ones covered this time we use a structure to enforce this
alignment, with the added need for __aligned(8) to ensure 8 byte
alignment of the timestamp on x86_32 and similar platforms where
it would be 4 byte aligned giving different padded from some other
architectures.
Patches to make this requirement clearer and potentially cause an
error print will follow once we've cleaned up existing cases.
Note that it is a very hard to hit problem and as a result of this
as we only have one bug report despite the problem being present
for many years.
Other fixes:
* cros_ec:
- set gyroscope default frequency. For some older boards not having
this set can lead to a choice that doesn't work.
* counter,microchip-tcb-capture:
- Fix a wrong value check in error check.
* mcp3422
- Fix locking to protect against race condition.
* meson-adc
- Use right device when looking up fuse values for calibration.
* rockchip-adc

The basic permission bits (protection bits in AmigaOS) have been broken
in Linux' AFFS - it would only set bits, but never delete them.
Also, contrary to the documentation, the Archived bit was not handled.
Let's fix this for good, and set the bits such that Linux and classic
AmigaOS can coexist in the most peaceful manner.
Also, update the documentation to represent the current state of things.

On the older-gen 32-bit SoCs the meson-saradc driver is used to read the
SoC temperature. This requires reading calibration data from the eFuse.
Looking up the calibration data nvmem-cell requires the OF device_node
pointer to be available in the struct device which is passed to
devm_nvmem_cell_get(). This however got lost with commit 8cb631ccbb1952
("iio: Remove superfluous of_node assignments") from indio_dev->dev. As
devm_nvmem_cell_get() is called in the initialization phase the
device_node is not yet available because the NVMEM cell is looked up
before iio_device_register() is called (which would then set the
device_node automatically).
Use the parent device to look up the NVMEM cell instead to fix this
issue.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to a suitable structure in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart
from previous readings.
The explicit alignment of ts is necessary to ensure correct padding
on architectures where s64 is only 4 bytes aligned such as x86_32.

The Saitek X52 family of joysticks has a pair of axes that were
originally (by the Windows driver) used as mouse pointer controls. The
corresponding usage page is the Game Controls page, which is not
recognized by the generic HID driver, and therefore, both axes get
mapped to ABS_MISC. The quirk makes the second axis get mapped to
ABS_MISC+1, and therefore made available separately.
One Saitek X52 device is already fixed. This patch fixes the other two
