Pull CXL (Compute Express Link) updates from Dan Williams:
 "The bulk of this update is support for enumerating the performance
  capabilities of CXL memory targets and connecting that to a platform
  CXL memory QoS class. Some follow-on work remains to hook up this data
  into core-mm policy, but that is saved for v6.9.

  The next significant update is unifying how CXL event records (things
  like background scrub errors) are processed between so called
  "firmware first" and native error record retrieval. The CXL driver
  handler that processes the record retrieved from the device mailbox is
  now the handler for that same record format coming from an EFI/ACPI
  notification source.

  This also contains miscellaneous feature updates, like Get Timestamp,
  and other fixups.

  Summary:

   - Add support for parsing the Coherent Device Attribute Table (CDAT)

   - Add support for calculating a platform CXL QoS class from CDAT data

   - Unify the tracing of EFI CXL Events with native CXL Events.

   - Add Get Timestamp support

   - Miscellaneous cleanups and fixups"

 "Here are the set of driver core and kernfs changes for 6.8-rc1.
  Nothing major in here this release cycle, just lots of small cleanups
  and some tweaks on kernfs that in the very end, got reverted and will
  come back in a safer way next release cycle.

  Included in here are:

   - more driver core 'const' cleanups and fixes

   - fw_devlink=rpm is now the default behavior

   - kernfs tiny changes to remove some string functions

   - cpu handling in the driver core is updated to work better on many
     systems that add topologies and cpus after booting

   - other minor changes and cleanups

  All of the cpu handling patches have been acked by the respective
  maintainers and are coming in here in one series. Everything has been

Pull thermal control updates from Rafael Wysocki:
 "These add support for the D1/T113s THS controller to the sun8i driver
  and a DT-based mechanism for platforms to indicate a preference to
  reboot (instead of shutting down) on crossing a critical trip point,
  fix issues, make other improvements (in the IPA governor, the Intel
  HFI driver, the exynos driver and the thermal netlink interface among
  other places) and clean up code.

  One long-standing issue addressed here is that trip point crossing
  notifications sent to user space might be unreliable due to the
  incorrect handling of trip point hysteresis in the thermal core:
  multiple notifications might be sent for the same event or there might
  be events without any notification at all.

  Specifics:

   - Add dynamic thresholds for trip point crossing detection to prevent
     trip point crossing notifications from being sent at incorrect
     times or not at all in some cases (Rafael J. Wysocki)

   - Fix synchronization issues related to the resume of thermal zones
     during a system-wide resume and allow thermal zones to be resumed
     concurrently (Rafael J. Wysocki)

   - Modify the thermal zone unregistration to wait for the given zone
     to go away completely before returning to the caller and rework the
     sysfs interface for trip points on top of that (Rafael J. Wysocki)

   - Fix a possible NULL pointer dereference in thermal zone
     registration error path (Rafael J. Wysocki)

   - Clean up the IPA thermal governor and modify it (with the help of a
     new governor callback) to avoid allocating and freeing memory every
     time its throttling callback is invoked (Lukasz Luba)

   - Make the IPA thermal governor handle thermal instance weight
     changes via sysfs correctly (Lukasz Luba)

   - Update the thermal netlink code to avoid sending messages if there
     are no recipients (Stanislaw Gruszka)

   - Convert Mediatek Thermal to the json-schema (Rafał Miłecki)

   - Fix thermal DT bindings issue on Loongson (Binbin Zhou)

   - Fix returning NULL instead of -ENODEV during thermal probe on
     Loogsoon (Binbin Zhou)

   - Add thermal DT binding for tsens on the SM8650 platform (Neil
     Armstrong)

   - Add reboot on the critical trip point crossing option feature
     (Fabio Estevam)

   - Use DEFINE_SIMPLE_DEV_PM_OPS do define PM functions for thermal
     suspend/resume on AmLogic (Uwe Kleine-König)

   - Add D1/T113s THS controller support to the Sun8i thermal control
     driver (Maxim Kiselev)

   - Fix example in the thermal DT binding for QCom SPMI (Johan Hovold)

   - Fix compilation warning in the tmon utility (Florian Eckert)

   - Add support for interrupt-based thermal configuration on Exynos
     along with a set of related cleanups (Mateusz Majewski)

   - Make the Intel HFI thermal driver enable an HFI instance (eg.
     processor package) from its first online CPU and disable it when
     the last CPU in it goes offline (Ricardo Neri)

   - Fix a kernel-doc warning and a spello in the cpuidle_cooling
     thermal driver (Randy Dunlap)

   - Move the .get_temp() thermal zone callback presence check to the
     thermal zone registration code (Daniel Lezcano)

   - Use the for_each_trip() macro for trip points table walks in a few
     places in the thermal core (Rafael J. Wysocki)

   - Make all trip point updates (via sysfs as well as from the platform
     firmware) trigger trip change notifications (Rafael J. Wysocki)

   - Drop redundant code from the thermal core and make one function in
     it take a const pointer argument (Rafael J. Wysocki)"
