The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang
barebone design which is sold under various brand names.
The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.
Adjust the pcspecialist_laptop[] DMI match table for this:
1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16
entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match
the laptop when sold by other vendors such as hyperbook.pl.
2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060)
models.
Note the .ident values of the dmi_system_id structs are left unset
since these are not used.

Add void *context arrgument to the list of arguments of
acpi_dev_install_notify_handler() and modify it to pass that argument
as context to acpi_install_notify_handler() instead of its first
argument which is problematic in general (for example, if platform
drivers used it, they would rather get struct platform_device pointers
or pointers to their private data from the context arguments of their
notify handlers).
Make all of the current callers of acpi_dev_install_notify_handler()
take this change into account so as to avoid altering the general
functionality.

Arm® Functional Fixed Hardware Specification defines LPI states,
which provide an architectural context loss flags field that can
be used to describe the context that might be lost when an LPI
state is entered.
- Core context Lost
- General purpose registers.
- Floating point and SIMD registers.
- System registers, include the System register based
- generic timer for the core.
- Debug register in the core power domain.
- PMU registers in the core power domain.
- Trace register in the core power domain.
- Trace context loss
- GICR
- GICD
Qualcomm's custom CPUs preserves the architectural state,
including keeping the power domain for local timers active.
when core is power gated, the local timers are sufficient to
wake the core up without needing broadcast timer.
The patch fixes the evaluation of cpuidle arch_flags, and moves only to
broadcast timer if core context lost is defined in ACPI LPI.

`strncpy()` is deprecated for use on NUL-terminated destination strings [1].
We know `osi->string` is a NUL-terminated string due to its eventual use
in `acpi_install_interface()` and `acpi_remove_interface()` which expect
a `acpi_string` which has been specifically typedef'd as:
| typedef char *acpi_string; /* Null terminated ASCII string */
... and which also has other string functions used on it like `strlen`.
Furthermore, padding is not needed in this instance either.
Due to the reasoning above a suitable replacement is `strscpy` [2] since
it guarantees NUL-termination on the destination buffer and doesn't
unnecessarily NUL-pad.
While there is unlikely to be a buffer overread (or other related bug)
in this case, we should still favor a more robust and less ambiguous
interface.

without copying the aer_capability_regs data. The pointer was to
the ghes->estatus buffer, which could be reused before
aer_recover_work_func() reads the data.
To avoid this problem, allocate a new aer_capability_regs structure
from the ghes_estatus_pool, copy the AER data from the ghes->estatus
buffer into it, pass a pointer to the new struct to
aer_recover_queue(), and free it after aer_recover_work_func() has
processed it.

Before this patch there were 6 dmi_system_id tables. While looking at
the override_table[] there are only 2 cases:
1. irq 1, level, active-low, not-shared, skip-override
2. irq 1, edge, activ-low, shared, force-override
Merge the dmi_system_id tables for identical cases together,
going from 6 dmi_system_id tables and 6 override_table[] entries
to just 2, one for each case.

Like various other ASUS ExpertBook-s, the ASUS ExpertBook B1402CBA
has an ACPI DSDT table that describes IRQ 1 as ActiveLow while
the kernel overrides it to EdgeHigh.
This prevents the keyboard from working. To fix this issue, add this laptop
to the skip_override_table so that the kernel does not override IRQ 1.

Like the Xiaomi Mi Pad 2 these 3 Lenovo x86 Android tablet models also
use a TI LP8557 backlight controller in direct I2C brightness register
control mode.
Add "vendor" quirks for these 3 models to disable the non-working
native / acpi_video backlight devices.

The Xiaomi Mi Pad 2 is currently listed under the:
"Models which should use the vendor backlight interface,
because of broken ACPI video backlight control." section.
But this is not 100% correct. The Xiaomi Mi Pad 2 is one of a set of
x86 tablets which shipped with Android as factory OS. These tablets
have a TI LP8557 backlight controller with its PWM input _not_
connected to the PMIC or chipset (LPSS) PWM output.
Instead the backlight can be controlled by configuring the LP8557
for direct control through its brightness I2C register and then
using the lp855x driver.
This setup means that neither i915's native or acpi_video backlight
control works, so a "vendor" quirk is added for these tablets to
disable both the native and acpi_video backlight devices, but these
devices do not use vendor control in the typical meaning of
vendor specific SMBIOS or ACPI calls being used.
This patch is a preparation patch for adding "vendor" quirks
for a couple more such tablet models.

A bug was introduced during unification of setting CAP_SMP_T_SWCOORD for
the _PDC and _OSC methods.
The third u32 in the buffer is never cleared before setting bits on it.
The memory is not guaranteed to be zero as it was allocated by kmalloc()
instead of kzalloc().
Fix this by initializing the third u32 in the buffer to 0.

Commit fd49f99c18 ("ACPI: NUMA: Add a node and memblk for each
CFMWS not in SRAT") did not account for the case where the BIOS
only partially describes a CFMWS Window in the SRAT. That means
the omitted address ranges, of a partially described CFMWS Window,
do not get assigned to a NUMA node.
Replace the call to phys_to_target_node() with numa_add_memblks().
Numa_add_memblks() searches an HPA range for existing memblk(s)
and extends those memblk(s) to fill the entire CFMWS Window.
Extending the existing memblks is a simple strategy that reuses
SRAT defined proximity domains from part of a window to fill out
the entire window, based on the knowledge* that all of a CFMWS
window is of a similar performance class.
*Note that this heuristic will evolve when CFMWS Windows present
a wider range of characteristics. The extension of the proximity
domain, implemented here, is likely a step in developing a more
sophisticated performance profile in the future.
There is no change in behavior when the SRAT does not describe
the CFMWS Window at all. In that case, a new NUMA node with a
single memblk covering the entire CFMWS Window is created.

The Itanium architecture is obsolete, and an informal survey [0] reveals
that any residual use of Itanium hardware in production is mostly HP-UX
or OpenVMS based. The use of Linux on Itanium appears to be limited to
enthusiasts that occasionally boot a fresh Linux kernel to see whether
things are still working as intended, and perhaps to churn out some
distro packages that are rarely used in practice.
None of the original companies behind Itanium still produce or support
any hardware or software for the architecture, and it is listed as
'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers
that contributed on behalf of those companies (nor anyone else, for that
matter) have been willing to support or maintain the architecture
upstream or even be responsible for applying the odd fix. The Intel
firmware team removed all IA-64 support from the Tianocore/EDK2
reference implementation of EFI in 2018. (Itanium is the original
architecture for which EFI was developed, and the way Linux supports it
deviates significantly from other architectures.) Some distros, such as
Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have
dropped support years ago.
While the argument is being made [1] that there is a 'for the common
good' angle to being able to build and run existing projects such as the
Grid Community Toolkit [2] on Itanium for interoperability testing, the
fact remains that none of those projects are known to be deployed on
Linux/ia64, and very few people actually have access to such a system in
the first place. Even if there were ways imaginable in which Linux/ia64
could be put to good use today, what matters is whether anyone is
actually doing that, and this does not appear to be the case.
There are no emulators widely available, and so boot testing Itanium is
generally infeasible for ordinary contributors. GCC still supports IA-64
but its compile farm [3] no longer has any IA-64 machines. GLIBC would
like to get rid of IA-64 [4] too because it would permit some overdue
code cleanups. In summary, the benefits to the ecosystem of having IA-64
be part of it are mostly theoretical, whereas the maintenance overhead
of keeping it supported is real.
So let's rip off the band aid, and remove the IA-64 arch code entirely.
This follows the timeline proposed by the Debian/ia64 maintainer [5],
which removes support in a controlled manner, leaving IA-64 in a known
good state in the most recent LTS release. Other projects will follow
once the kernel support is removed.

Passing a struct thermal_trip pointer instead of a trip index to the
.get_trend() thermal zone callback allows one of its 2 implementations,
the thermal_get_trend() function in the ACPI thermal driver, to be
simplified quite a bit, and the other implementation of it in the
ti-soc-thermal driver does not even use the relevant callback argument.
For this reason, change the .get_trend() thermal zone callback
definition and adjust the related code accordingly.

Instead of bypassing the kernel's adaptation layer for performing EFI
runtime calls, wire up ACPI PRM handling into it. This means these calls
can no longer occur concurrently with EFI runtime calls, and will be
made from the EFI runtime workqueue. It also means any page faults
occurring during PRM handling will be identified correctly as
originating in firmware code.

__efi_call_virt() exists as an alternative for efi_call_virt() for the
sole reason that ResetSystem() returns void, and so we cannot use a call
to it in the RHS of an assignment.
Given that there is only a single user, let's drop the macro, and expand
it into the caller. That way, the remaining macro can be tightened
somewhat in terms of type safety too.
Note that the use of typeof() on the runtime service invocation does not
result in an actual call being made, but it does require a few pointer
types to be fixed up and converted into the proper function pointer
prototypes.

Currently, the SystemCMOS address space handler is installed for the
ACPI RTC devices (PNP0B00/PNP0B01/PNP0B02) only. But there are platforms
with SystemCMOS Operetion Region defined under the ACPI Time and Alarm

Screen brightness can only be changed once on HP ZBook Fury 16 G10.
The vendor reports that the issue is related to the fact that Linux doesn't
invoke _PS0 at boot for all ACPI devices, as expected by the platform firmware:
Scope (\_SB.PC00.GFX0)
{
Scope (DD1F)
{
Method (_PS0, 0, Serialized) // _PS0: Power State 0
{
If (CondRefOf (\_SB.PC00.LPCB.EC0.SSBC))
{
\_SB.PC00.LPCB.EC0.SSBC ()
}
}
...
}
...
}
The \_SB.PC00.GFX0.DD1F is the panel device, and its _PS0 needs to be
executed at the initialization time to make the brightness control work
properly.
_PS0 is not evaluated for this device, because _PSC is missing,
which violates the ACPI specification (ACPI 6.5, section 7.3.6).
Commit b378549226 ("ACPI / PM: Do not power manage devices in unknown
initial states") tried to work around missing _PSC on platforms with
defective firmware, but got reverted due to a regression.
So the safest approach is to use acpi_device_fix_up_power_extended() to
put ACPI video and its child devices to D0 to address the issue at hand.

Inside IVSC, switching ownership requires an interface with two
different hardware modules, ACE and CSI. The software interface
to these modules is based on Intel MEI framework. Usually mei
client devices are dynamically created, so the info of consumers
depending on mei client devices is not present in the firmware
tables.
This causes problems with the probe ordering with respect to
drivers for consumers of these MEI client devices. But on these
camera sensor devices, the ACPI nodes describing the sensors all
have a _DEP dependency on the matching MEI bus ACPI device, so
adding IVSC MEI bus ACPI device to acpi_honor_dep_ids allows
solving the probe-ordering problem by deferring the enumeration of
ACPI-devices which have a _DEP dependency on an IVSC mei bus ACPI
device.
On TGL platform, the HID of IVSC MEI bus ACPI device is INTC1059,
and on ADL platform, the HID is INTC1095. So add both of them to
acpi_honor_dep_ids.

Move the acpi_bus_generate_netlink_event() invocation into
acpi_thermal_trips_update() which allows the code duplication in
acpi_thermal_notify() to be cleaned up, but for this purpose the
event value needs to be passed to acpi_thermal_trips_update() and
from there to acpi_thermal_adjust_thermal_zone() which has to

Rework the ACPI thermal driver's .get_trend() callback function,

Make the ACPI thermal driver use thermal_zone_device_register_with_trips()
to register its thermal zones.
For this purpose, make it create a trip point table that will be passed to
thermal_zone_device_register_with_trips() as an argument.
Also use the thermal_zone_update_trip_temp() helper introduced
previously to update temperatures of the passive and active trip
points after a trip points change notification from the platform
firmware.

There is a race condition between acpi_thermal_trips_update() and
acpi_thermal_check_fn(), because the trip points may get updated while
the latter is running which in theory may lead to inconsistent results.
For example, if two trips are updated together, using the temperature
value of one of them from before the update and the temperature value
of the other one from after the update may not lead to the expected
outcome.
Moreover, if thermal_get_trend() runs when a trip points update is in
progress, it may end up using stale trip point temperatures.
To address this, make acpi_thermal_trips_update() call
thermal_zone_device_exec() to carry out the trip points update and
use a new acpi_thermal_adjust_thermal_zone() wrapper around
__acpi_thermal_trips_update() as the callback function for the latter.
While at it, change the acpi_thermal_trips_update() return data type
to void as that function always returns 0 anyway.

Rename the trips variable in acpi_thermal_register_thermal_zone() to
