The ASUS ROG Flow Z13-KJP GZ302EAC model uses sys_vendor name ASUS
rather than ASUSTeK COMPUTER INC., but it needs the same folio quirk as
the other ROG Flow Z13. To keep things simple, just match on sys_vendor
ASUS since it covers both.

The gz_chain_head variable has been unused since the driver's initial
addition to the tree. Its use was eliminated between v3 and v4 during
development but due to the reference of gz_chain_head's wait_list
member, the compiler could not warn that it was unused.
After a (tip) commit ("locking/rwsem: Remove the list_head from struct
rw_semaphore"), which removed a reference to the variable passed to
__RWSEM_INITIALIZER(), certain configurations show an unused variable
warning from the Lenovo wmi-gamezone driver:
drivers/platform/x86/lenovo/wmi-gamezone.c:34:31: warning: 'gz_chain_head' defined but not used [-Wunused-variable]

The HP Omen 16-k0xxx (board ID: 8A4D) has the same WMI interface as
other Victus S boards, but requires additional quirks for correctly
switching thermal profile.
Create a new quirk omen_v1_legacy_thermal_params which allows a board to
use Omen V1 thermal values, but rely on the older legacy
HP_OMEN_EC_THERMAL_PROFILE_OFFSET. Add the DMI board name to
victus_s_thermal_profile_boards[] table and map it to the newly added
quirk.
Testing on board 8A4D confirmed that platform profile is registered
successfully and fan RPMs are readable and controllable.

It turns out that both sysfs attributes actually directly control
the FN lock status/super key enable status, rather than the
triggering of the associated events. This behavior was first observed
on a Tuxedo notebook and was belived to be a hardware quirk.
However, it seems that i simply misunderstood the manual of the
OEM software for Intel NUC devices. The correct behavior is:
- fn_lock_toggle_enable enables/disables FN lock mode
- super_key_toggle_enable enables/disables the super key
Rename both sysfs attributes to avoid confusing users.

The Lenovo ThinkPad X1 Fold 16 Gen 1 has an OV5675 sensor (ACPI HID
OVTI5675) behind an INT3472 discrete PMIC controller. The INT3472
_DSM returns GPIO type 0x10 for one of the pins, which controls the
DOVDD (digital I/O power) regulator enable.
Type 0x10 is not currently handled by the driver, causing the GPIO to
be ignored with a warning. Add INT3472_GPIO_TYPE_DOVDD (0x10) and
handle it as a regulator with con_id "dovdd" to match the supply name
used by sensor drivers (e.g. ov5675).
Also increase GPIO_SUPPLY_NAME_LENGTH from 5 to 6 to accommodate
the "dovdd" name (5 chars + null terminator).

The HP Omen 16-wf0xxx (board ID: 8BAB) has the same WMI interface as
other Victus S boards, but requires quirks for correctly switching
thermal profile (similar to HP Omen 16-wf1xxx, board ID: 8C78).
Add the DMI board name to victus_s_thermal_profile_boards[] table and
map it to omen_v1_thermal_params.
Testing on HP Omen 16-wf0xxx confirmed that platform profile is
registered successfully and fan RPMs are readable and controllable.

on SUPI S10
The touchscreen on the SUPI S10 tablet reports inverted Y coordinates,
causing touch input to be mirrored vertically relative to the display.
Add a quirk to set the "touchscreen-inverted-y" boolean device-property
on the touchscreen device, so that the goodix_ts driver will fixup
the coordinates.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.
As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

The LWMI_SUPP_MAY_{GET,SET} macros are fundamentally broken. When I
introduced them, I meant to check LWMI_SUPP_VALID *and* the
corresponding bits for get/set capabilities. However, `supported &
LWMI_SUPP_MAY_{GET,SET}' means *or*, so it accidentally passes the check
when LWMI_SUPP_VALID is set.
Fix them by only including the corresponding get/set bit without
LWMI_SUPP_VALID. Meanwhile, rename them to LWMI_SUPP_{GET,SET} to make
them less confusing.

Pull ACPI updates from Rafael Wysocki:
"This one is significantly larger than previous ACPI support pull
requests because several significant updates have coincided in it.
First, there is a routine ACPICA code update, to upstream version
20251212, but this time it covers new ACPI 6.6 material that has not
been covered yet. Among other things, it includes definitions of a few
new ACPI tables and updates of some others, like the GICv5 MADT
structures and ARM IORT IWB node definitions that are used for adding
GICv5 ACPI probing on ARM (that technically is IRQ subsystem material,
but it depends on the ACPICA changes, so it is included here). The
latter alone adds a few hundred lines of new code.
Second, there is an update of ACPI _OSC handling including a fix that
prevents failures from occurring in some corner cases due to careless
handling of _OSC error bits.
On top of that, the "system resource" ACPI device objects with the
PNP0C01 and PNP0C02 are now going to be handled by the ACPI core
device enumeration code instead of handing them over to the legacy PNP
system driver which causes device enumeration issues to occur. Some of
those issues have been worked around in device drivers and elsewhere
and those workarounds should not be necessary any more, so they are
going away.
Moreover, the time has come to convert all "core ACPI" device drivers
that were still using struct acpi_driver objects for device binding
into proper platform drivers that use struct platform_driver for this
purpose. These updates are accompanied by some requisite core ACPI
device enumeration code changes.
Next, there are ACPI APEI updates, including changes to avoid excess
overhead in the NMI handler and in SEA on the ARM side, changes to
unify ACPI-based HW error tracing and logging, and changes to prevent
APEI code from reaching out of its allocated memory.
There are also some ACPI power management updates, mostly related to
the ACPI cpuidle support in the processor driver, suspend-to-idle
handling on systems with ACPI support and to ACPI PM of devices.
In addition to the above, bugs are fixed and the code is cleaned up in
assorted places all over.
Specifics:
- Update the ACPICA code in the kernel to upstream version 20251212
which includes the following changes:
* Add support for new ACPI table DTPR (Michal Camacho Romero)
* Release objects with acpi_ut_delete_object_desc() (Zilin Guan)
* Add UUIDs for Microsoft fan extensions and UUIDs associated with
TPM 2.0 devices (Armin Wolf)
* Fix NULL pointer dereference in acpi_ev_address_space_dispatch()
(Alexey Simakov)
* Add KEYP ACPI table definition (Dave Jiang)
* Add support for the Microsoft display mux _OSI string (Armin
Wolf)
* Add definitions for the IOVT ACPI table (Xianglai Li)
* Abort AML bytecode execution on AML_FATAL_OP (Armin Wolf)
* Include all fields in subtable type1 for PPTT (Ben Horgan)
* Add GICv5 MADT structures and Arm IORT IWB node definitions
(Jose Marinho)
* Update Parameter Block structure for RAS2 and add a new flag in
Memory Affinity Structure for SRAT (Pawel Chmielewski)
* Add _VDM (Voltage Domain) object (Pawel Chmielewski)
- Add support for GICv5 ACPI probing on ARM which is based on the
GICv5 MADT structures and ARM IORT IWB node definitions recently
added to ACPICA (Lorenzo Pieralisi)
- Rework ACPI PM notification setup for PCI root buses and modify the
ACPI PM setup for devices to register wakeup source objects under
physical (that is, PCI, platform, etc.) devices instead of doing
that under their ACPI companions (Rafael Wysocki)
- Adjust debug messages regarding postponed ACPI PM printed during
system resume to be more accurate (Rafael Wysocki)
- Remove dead code from lps0_device_attach() (Gergo Koteles)
- Start to invoke Microsoft Function 9 (Turn On Display) of the Low-
Power S0 Idle (LPS0) _DSM in the suspend-to-idle resume flow on
systems with ACPI LPS0 support to address a functional issue on
Lenovo Yoga Slim 7i Aura (15ILL9), where system fans and keyboard
backlights fail to resume after suspend (Jakob Riemenschneider)
- Add sysfs attribute cid for exposing _CID lists under ACPI device
objects (Rafael Wysocki)
- Replace sprintf() with sysfs_emit() in all of the core ACPI sysfs
interface code (Sumeet Pawnikar)
- Use acpi_get_local_u64_address() in the code implementing ACPI
support for PCI to evaluate _ADR instead of evaluating that object
directly (Andy Shevchenko)
- Add JWIPC JVC9100 to irq1_level_low_skip_override[] to unbreak
serial IRQs on that system (Ai Chao)
- Fix handling of _OSC errors in acpi_run_osc() to avoid failures on
systems where _OSC error bits are set even though the _OSC return
buffer contains acknowledged feature bits (Rafael Wysocki)
- Clean up and rearrange \_SB._OSC handling for general platform
features and USB4 features to avoid code duplication and
unnecessary memory management overhead (Rafael Wysocki)
- Make the ACPI core device enumeration code handle PNP0C01 and
PNP0C02 ("system resource") device objects directly instead of
letting the legacy PNP system driver handle them to avoid device
enumeration issues on systems where PNP0C02 is present in the _CID
list under ACPI device objects with a _HID matching a proper device
driver in Linux (Rafael Wysocki)

- Use async schedule function in acpi_scan_clear_dep_fn() to avoid
races with user space initialization on some systems (Yicong Yang)
- Add a piece of documentation explaining why binding drivers
directly to ACPI device objects is not a good idea in general and
why it is desirable to convert drivers doing so into proper
platform drivers that use struct platform_driver for device binding
(Rafael Wysocki)
- Convert multiple "core ACPI" drivers, including the NFIT ACPI

thermal zone driver, the ACPI hardware event device (HED) driver,
the ACPI EC driver, the ACPI SMBUS HC driver, the ACPI Smart
Battery Subsystem (SBS) driver, and the ACPI backlight (video)

ACPI battery driver (Ata İlhan Köktürk)
- Use LIST_HEAD() for initializing a stack-allocated list in the

Passing IRQF_ONESHOT ensures that the interrupt source is masked until the
secondary (threaded) handler is done. If only a primary handler is used
then the flag makes no sense because the interrupt cannot fire (again)
while its handler is running.
The flag also prevents force-threading of the primary handler and the
irq-core will warn about this.
The flag was added to match the flag on the shared handler which uses a
threaded handler and therefore IRQF_ONESHOT. This is no longer needed
because devm_request_irq() now passes IRQF_COND_ONESHOT for this case.
Revert adding IRQF_ONESHOT to irqflags.
