Implements platform profile support for Dell laptops with new WMAX thermal
interface, present on some Alienware X-Series, Alienware M-Series and
Dell's G-Series laptops. This interface is suspected to be used by
Alienware Command Center (AWCC), which is not available for linux
systems, to manage thermal profiles.
This implementation makes use of three WMI methods, namely
THERMAL_CONTROL, THERMAL_INFORMATION and GAME_SHIFT_STATUS, which take
u32 as input and output arguments. Each method has a set of supported
operations specified in their respective enums.
Not all models with WMAX WMI interface support these methods. Because of
this, models have to manually declare support through new quirks
`thermal` for THERMAL_CONTROL and THERMAL_INFORMATION and `gmode` for
GAME_SHIFT_STATUS.
Wrappers written for these methods support multiple operations.
THERMAL_CONTROL switches thermal modes through operation
ACTIVATE_PROFILE. Available thermal codes are auto-detected at runtime
and matched against a list of known thermal codes:
Thermal Table "User Selectable Thermal Tables" (USTT):
BALANCED 0xA0
BALANCED_PERFORMANCE 0xA1
COOL 0xA2
QUIET 0xA3
PERFORMANCE 0xA4
LOW_POWER 0xA5
Thermal Table Basic:
QUIET 0x96
BALANCED 0x97
BALANCED_PERFORMANCE 0x98
PERFORMANCE 0x99
Devices are known to implement only one of these tables without mixing
their thermal codes.
The fact that the least significant digit of every thermal code is
consecutive of one another is exploited to efficiently match codes
through arrays.
Autodetection of available codes is done through operation LIST_IDS of
method THERMAL_INFORMATION. This operation lists fan IDs, CPU sensor ID,
GPU sensor ID and available thermal profile codes, *in that order*. As
number of fans and thermal codes is very model dependent, almost every
ID is scanned and matched based on conditions found on
is_wmax_thermal_code(). The known upper bound for the number of IDs is
13, corresponding to a device that have 4 fans, 2 sensors and 7 thermal
codes.
Additionally G-Series laptops have a key called G-key, which (with AWCC
proprietary driver) switches the thermal mode to an special mode named
GMODE with code 0xAB and changes Game Shift Status to 1. Game Shift is a
mode the manufacturer claims, increases gaming performance.
GAME_SHIFT_STATUS method is used to mimic this behavior when selecting
PLATFORM_PROFILE_PERFORMANCE option.
All of these profiles are known to only change fan speed profiles,
although there are untested claims that some of them also change power
profiles.
Activating a thermal mode with method THERMAL_CONTROL may cause short
hangs. This is a known problem present on every platform.

When performing a system shutdown under Windows, all WMI clients are
terminated. This means that the ACPI BIOS might expect all WMI devices
to be disabled when shutting down.
Emulate this behaviour by disabling all active WMI devices during
shutdown. Also introduce a new WMI driver callback to allow WMI drivers
to perform any device-specific actions before disabling the WMI device.
Tested on a Dell Inspiron 3505.

The cpu_emergency_register_virt_callback() function is used
unconditionally by the x86 kvm code, but it is declared (and defined)
conditionally:
#if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD)
void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback);
...
leading to a build error when neither KVM_INTEL nor KVM_AMD support is
enabled:
arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’:
arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration]

12522 | cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix the build by defining empty helper functions the same way the old
cpu_emergency_disable_virtualization() function was dealt with for the
same situation.
Maybe we could instead have made the call sites conditional, since the
callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak
fallback. I'll leave that to the kvm people to argue about, this at
least gets the build going for that particular config.

I2C host fixes for v6.12-rc1 (from Andi)
The DesignWare driver now has the correct ENABLE-ABORT sequence,
ensuring ABORT can always be sent when needed.
In the SynQuacer controller we now check for PCLK as an optional
clock, allowing ACPI to directly provide the clock rate.
The recent KEBA driver required a dependency fix in Kconfig.
The XIIC driver now has a corrected power suspend sequence.

Assorted minor syzbot fixes, and for bigger stuff:
- Fix two disk accounting rewrite bugs
- Disk accounting keys use the version field of bkey so that journal
replay can tell which updates have been applied to the btree. This is
set in the transaction commit path, after we've gotten our journal
reservation (and our time ordering), but the
BCH_TRANS_COMMIT_skip_accounting_apply flag that journal replay uses
was incorrectly skipping this for new updates generated prior to
journal replay.
This fixes the underlying cause of an assertion pop in
disk_accounting_read.
- A couple fixes for disk accounting + device removal. Checking if
acocunting replicas entries were marked in the superblock was being
done at the wrong point, when deltas in the journal could still zero
them out, and then additionally we'd try to add a missing replicas
entry to the superblock without checking if it referred to an invalid
(removed) device.
- A whole slew of repair fixes
- fix infinite loop in propagate_key_to_snapshot_leaves(), this fixes
an infinite loop when repairing a filesystem with many snapshots
- fix incorrect transaction restart handling leading to occasional
"fsck counted ..." warnings"
- fix warning in __bch2_fsck_err() for bkey fsck errors
- check_inode() in fsck now correctly checks if the filesystem was
clean
- there shouldn't be pending logged ops if the fs was clean, we now
check for this
- remove_backpointer() doesn't remove a dirent that doesn't actually
point to the inode
- many more fsck errors are AUTOFIX
