Some more recent TUF laptops have both fan_boost and thermal_throttle.
The key code for Fn+F5 is also different and unmapped.
This patch adjusts the asus_wmi_handle_event_code() match to match
for both 0x99 and 0xAE, and run both mode switch functions for
fan_boost and/or thermal_throttle if either are available.
It is required that both are tried, as in some instances the ACPI
set-method for one may not have any code body within it even though
it was returned as supported by the get method.

Simplify tablet-mode-switch handling:
1. The code is the same for all variants, the only difference is the
dev_id and notify event code. Store the dev_id + code in struct asus_wmi
and unify the handling
2. Make the new unified asus_wmi_tablet_mode_get_state() check dev_id has
been set and make it a no-op when not set. This allows calling it
unconditionally at resume/restore time
3. Simplify the tablet_mode_sw module-param handling, this also allows
selecting the new lid-flip-rog type through the module-param.

Support the hardware GPU MUX switch available on some models. This
switch can toggle the MUX between:
- 0, Dedicated mode
- 1, Optimus mode
Optimus mode is the regular iGPU + dGPU available, while dedicated

This means the simpler asus_wmi_dev_is_present() can be used in
*_check_present() - it is not an error for these methods to be
missing.
The _write() functions have their bodies shifted in to *_store()

This feature has 3 modes quiet, balanced, performance
The objective of this feature is to track the moving average of system
power over the time period specified and switch to the subsequent mode.
In order to do this, PMF driver will get the moving average of APU power
from PMFW and power threshold, time constants, system config parameters
from OEM inputs.
System power as read by PMF driver from PMFW is the filtered value over
the sampling window. Every sampling window, moving average of system power
is computed. At the end of the monitoring window, the moving average is
compared against the threshold for mode switch for decision making.
With AMD managing the system config limits, any mode switch within
auto-mode will result in limits of fPPT/sPPT/STAPM or STT being scaled
down.
When "auto mode" is enabled, the static slider control remains out of
the PMF driver, so the platform_profile registration would not
happen in PMF driver.
The transition to auto-mode only happens when the APMF fn5 is enabled
in BIOS, platform_profile set to "balanced" and a AMT
(Auto Mode transition) is received.

PMF has a generic interface defined via PMF ACPI fn9 for influencing fan
policy during mode switch.
PMF ACPI fn9 will normally be invoked when AMDPMF needs to change the fan
table index for the EC. When AMDPMF is loaded this function will be invoked
to change fan speed. OEM can also choose to report the actual fan table
index and fan RPM to PMF through OEM structure.
This information will be communicated by PMF driver to customer BIOS.

PMF driver can send periodic heartbeat signals to OEM BIOS. When BIOS does
not receive the signal after a period of time, it can infer that AMDPMF
has hung or failed to load.
In this situation, BIOS can fallback to legacy operations. OEM can modify
the time interval of the signal or completely disable signals through
ACPI Method.

SPS (a.k.a. Static Power Slider) gives a feel of Windows performance
power slider for the Linux users, where the user selects a certain
mode (like "balanced", "low-power" or "performance") and the thermals
associated with each selected mode gets applied from the silicon
side via the mailboxes defined through PMFW.
PMF driver hooks to platform_profile by reading the PMF ACPI fn9 to
see if the support is being advertised by ACPI interface.
If supported, the PMF driver reacts to platform_profile selection choices
made by the user and adjust the system thermal behavior.

PMF driver implements the ACPI methods as defined by AMD for PMF Support.
The ACPI layer acts as a glue that helps in providing the infrastructure
for OEMs customization.
OEMs can refer to PMF support documentation to decide on the list of
functions to be supported on their specific platform model.
AMD mandates that PMF ACPI fn0 and fn1 to be implemented which
provides the set of functions, params and the notifications that
would be sent to PMF driver so that PMF driver can adapt and
react.

Enable multipage folio support for the afs filesystem.
Support has already been implemented in netfslib, fscache and cachefiles

Note that it does require a change to afs_write_begin() to return the
correct subpage. This is a "temporary" change as we're working on
getting rid of the need for ->write_begin() and ->write_end()
completely, at least as far as network filesystems are concerned - but
it doesn't prevent afs from making use of the capability.
