Pull ACPI updates from Rafael Wysocki:
 "These fix issues, add new quirks, rearrange the IRQ override quirk
  definitions, add new helpers and switch over code to using them,
  rework a couple of interfaces to be more flexible, eliminate strncpy()
  usage from PNP, extend the ACPI PCC mailbox driver and clean up code.

  This is based on ACPI thermal driver changes that are present in the
  thermal control updates for 6.7-rc1 pull request (they are depended on
  by the ACPI utilities updates). However, the ACPI thermal driver
  changes are not included in the list of specific ACPI changes below.

  Specifics:

   - Add symbol definitions related to CDAT to the ACPICA code (Dave
     Jiang)

   - Use the acpi_device_is_present() helper in more places and rename
     acpi_scan_device_not_present() to be about enumeration (James

   - Clean up departures from kernel coding style in the low-level
     interface for ACPICA (Jonathan Bergh)

   - Replace strncpy() with strscpy() in acpi_osi_setup() (Justin Stitt)

     including size computation (Rafael Wysocki)

   - Clean up ACPI utilities code so as to make it follow the kernel
     coding style (Jonathan Bergh)

   - Consolidate IRQ trigger-type override DMI tables and drop .ident
     values from dmi_system_id tables used for ACPI resources management
     quirks (Hans de Goede)

   - Add ACPI IRQ override for TongFang GMxXGxx (Werner Sembach)

   - Allow _DSD buffer data only for byte accessors and document the
     _DSD data buffer GUID (Andy Shevchenko)

   - Drop BayTrail and Lynxpoint pinctrl device IDs from the ACPI LPSS
     driver, because it does not need them (Raag Jadav)

   - Add acpi_backlight=vendor quirk for Toshiba Portégé R100 (Ondrej
     Zary)

   - Add "vendor" backlight quirks for 3 Lenovo x86 Android tablets
     (Hans de Goede)

     documentation (Rafael Wysocki)

Pull x86 core updates from Thomas Gleixner:

 - Limit the hardcoded topology quirk for Hygon CPUs to those which have
   a model ID less than 4.

   The newer models have the topology CPUID leaf 0xB correctly
   implemented and are not affected.

 - Make SMT control more robust against enumeration failures

   SMT control was added to allow controlling SMT at boottime or
   runtime. The primary purpose was to provide a simple mechanism to
   disable SMT in the light of speculation attack vectors.

   It turned out that the code is sensible to enumeration failures and
   worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration
   which means the primary thread mask is not set up correctly. By
   chance a XEN/PV boot ends up with smp_num_siblings == 2, which makes
   the hotplug control stay at its default value "enabled". So the mask
   is never evaluated.

   The ongoing rework of the topology evaluation caused XEN/PV to end up
   with smp_num_siblings == 1, which sets the SMT control to "not
   supported" and the empty primary thread mask causes the hotplug core
   to deny the bringup of the APS.

   Make the decision logic more robust and take 'not supported' and 'not
   implemented' into account for the decision whether a CPU should be
   booted or not.

 - Fake primary thread mask for XEN/PV

   Pretend that all XEN/PV vCPUs are primary threads, which makes the
   usage of the primary thread mask valid on XEN/PV. That is consistent
   with because all of the topology information on XEN/PV is fake or
   even non-existent.

 - Encapsulate topology information in cpuinfo_x86

   Move the randomly scattered topology data into a separate data
   structure for readability and as a preparatory step for the topology
   evaluation overhaul.

 - Consolidate APIC ID data type to u32

   It's fixed width hardware data and not randomly u16, int, unsigned
   long or whatever developers decided to use.

 - Cure the abuse of cpuinfo for persisting logical IDs.

   Per CPU cpuinfo is used to persist the logical package and die IDs.
   That's really not the right place simply because cpuinfo is subject
   to be reinitialized when a CPU goes through an offline/online cycle.

   Use separate per CPU data for the persisting to enable the further
   topology management rework. It will be removed once the new topology
   management is in place.

 - Provide a debug interface for inspecting topology information

   Useful in general and extremly helpful for validating the topology
   management rework in terms of correctness or "bug" compatibility.

Extend aquacomputer_d5next driver to expose various hardware sensors of the
Aquacomputer High Flow USB flow sensor, which communicates through a
proprietary USB HID protocol. This commit also adds support for the sensors
of the MPS Flow devices, as they have the same USB product ID and sensor
layouts. Implemented by Leonard Anderweit [1].

Internal and external temp sensor readings are available, along with
the flow sensor.

Additionally, serial number and firmware version are exposed through
debugfs.

Add support for LTC2991 Octal I2C Voltage, Current, and Temperature
Monitor.

The LTC2991 is used to monitor system temperatures, voltages and
currents. Through the I2C serial interface, the eight monitors can
individually measure supply voltages and can be paired for
differential measurements of current sense resistors or temperature
sensing transistors. Additional measurements include internal
temperature and internal VCC.

The MAX31785 has shown erratic behaviour across multiple system
designs, unexpectedly clock stretching and NAKing transactions.

Experimentation shows that this seems to be triggered by a register access
directly back to back with a previous register write. Experimentation also
shows that inserting a small delay after register writes makes the issue go
away.

Use a similar solution to what the max15301 driver does to solve the same
problem. Create a custom set of bus read and write functions that make sure
that the delay is added.
