      Pull thermal control updates from Rafael Wysocki:
 "These mostly continue to rework the thermal core and the thermal zone
  driver interface to make the code more straightforward and reduce
  bloat

  The most significant piece of this work is a change of the code
  related to binding cooling devices to thermal zones which, among other
  things, replaces two previously existing thermal zone operations with
  one allowing driver implementations to be much simpler

  There is also a new thermal core testing module allowing mock thermal
  zones to be created and controlled via debugfs in order to exercise
  the thermal core functionality. It is expected to be used for
  implementing thermal core self tests in the future

  Apart from the above, there are assorted thermal driver updates

  Specifics:

   - Update some thermal drivers to eliminate thermal_zone_get_trip()
     calls from them and get rid of that function (Rafael Wysocki)

   - Update the thermal sysfs code to store trip point attributes in
     trip descriptors and get to trip points via attribute pointers
     (Rafael Wysocki)

   - Move the computation of the low and high boundaries for
     thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
     Lezcano)

   - Introduce a debugfs-based facility for thermal core testing (Rafael
     Wysocki)

   - Replace the thermal zone .bind() and .unbind() callbacks for
     binding cooling devices to thermal zones with one .should_bind()
     callback used for deciding whether or not a given cooling devices
     should be bound to a given trip point in a given thermal zone
     (Rafael Wysocki)

   - Eliminate code that has no more users after the other changes, drop
     some redundant checks from the thermal core and clean it up (Rafael
     Wysocki)

   - Fix rounding of delay jiffies in the thermal core (Rafael Wysocki)

   - Refuse to accept trip point temperature or hysteresis that would
     lead to an invalid threshold value when setting them via sysfs
     (Rafael Wysocki)

   - Adjust states of all uninitialized instances in the .manage()
     callback of the Bang-bang thermal governor (Rafael Wysocki)

   - Drop a couple of redundant checks along with the code depending on
     them from the thermal core (Rafael Wysocki)

   - Rearrange the thermal core to avoid redundant checks and simplify
     control flow in a couple of code paths (Rafael Wysocki)

   - Add power domain DT bindings for new Amlogic SoCs (Georges Stark)

   - Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST
     driver and add a Kconfig dependency on THERMAL_OF subsystem for the
     STi driver (Raphael Gallais-Pou)

   - Simplify the error code path in the probe functions in the brcmstb
     driver with the helo of dev_err_probe() (Yan Zhen)

   - Make imx_sc_thermal use dev_err_probe() (Alexander Stein)

   - Remove trailing space after \n newline in the Renesas driver (Colin
     Ian King)

   - Add DT binding compatible string for the SA8255p to the tsens
     thermal driver (Nikunj Kela)

   - Use the devm_clk_get_enabled() helpers to simplify the init routine
     in the sprd thermal driver (Huan Yang)

   - Remove __maybe_unused notations for the functions by using the new
     RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros on the IMx and
     Qoriq drivers (Fabio Estevam)

   - Remove unused declarations from the ti-soc-thermal driver's header
     file as the functions in question were removed previously (Zhang
     Zekun)"

      Pull power management updates from Rafael Wysocki:
 "By the number of new lines of code, the most visible change here is
  the addition of hybrid CPU capacity scaling support to the
  intel_pstate driver. Next are the amd-pstate driver changes related to
  the calculation of the AMD boost numerator and preferred core
  detection.

  As far as new hardware support is concerned, the intel_idle driver
  will now handle Granite Rapids Xeon processors natively, the
  intel_rapl power capping driver will recognize family 1Ah of AMD
  processors and Intel ArrowLake-U chipos, and intel_pstate will handle
  Granite Rapids and Sierra Forest chips in the out-of-band (OOB) mode.

     limits, which fixes the masking hardware problems (Mario
     Limonciello)

 "These are the non-x86 changes (mostly ARM, as is usually the case).

     infrastructure

   - FP8 support

   - Nested virtualization now supports the address translation
     (FEAT_ATS1A) family of instructions

   - Add selftest checks for a bunch of timer emulation corner cases

   - Prevent MTE tags being restored by userspace if we are actively
     logging writes, as that's a recipe for disaster

   - Correct the refcount on a page that is not considered for MTE tag
     copying (such as a device)

   - When walking a page table to split block mappings, synchronize only
     at the end the walk rather than on every store

   - Fix boundary check when transfering memory using FFA

   - Fix pKVM TLB invalidation, only affecting currently out of tree
     code but worth addressing for peace of mind

  LoongArch:

   - Revert qspinlock to test-and-set simple lock on VM.

   - Add Loongson Binary Translation extension support.

   - Add PMU support for guest.

   - Enable paravirt feature control from VMM.

   - Implement function kvm_para_has_feature().

  RISC-V:

   - Fix sbiret init before forwarding to userspace

   - Don't zero-out PMU snapshot area before freeing data

      Pull networking updates from Jakub Kicinski:
 "The zero-copy changes are relatively significant, but regression risk
  should be contained. The feature needs to be used to cause trouble.

  Also it feels like we got an order of magnitude more semi-automated
  "refactoring" chaff than usual, I wonder if it's just us.

  Core & protocols:

   - Support Device Memory TCP, ability to zero-copy receive TCP
     payloads to a DMABUF region of memory while packet headers land
     separately in normal kernel buffers, and TCP processes then as
     usual.

   - The ability to read the PTP PHC (Physical Hardware Clock) alongside
     MONOTONIC_RAW timestamps with PTP_SYS_OFFSET_EXTENDED. Previously
     only CLOCK_REALTIME was supported.

   - Allow matching on all bits of IP DSCP for routing decisions.
     Previously we only supported on matching TOS bits in IPv4 which is
     a narrower interpretation of the same header field.

   - Increase the range of weights used for multi-path routing from
     8 bits to 16 bits.

   - Add support for IPv6 PIO p flag in the Prefix Information Option
     per draft-ietf-6man-pio-pflag.

   - IPv6 IOAM6 support for new tunsrc encap mode for better
     performance.

   - Detect destinations which blackhole MPTCP traffic and avoid
     initiating MPTCP connections to them for a certain period of time,
     1h by default.

   - Improve IPsec control path performance by removing the inexact
     policies list.

   - AF_VSOCK: add support for SIOCOUTQ ioctl.

   - Add enum for reasons TCP reset was sent for easier tracing.

   - Add SMC ringbufs usage statistics.

  Drivers:

   - Handle netconsole setup failures more gracefully, don't fail
     loading, retain the specified target as disabled.

   - Extend bonding's IPsec offload pass thru capabilities (ESN, stats).

  Filtering:

   - Add TCP_BPF_SOCK_OPS_CB_FLAGS to bpf_*sockopt() to address the case
     when long-lived sockets miss a chance to set additional callbacks
     if a sockops program was not attached early in their lifetime.

   - Support using BPF skb helpers in tracepoints.

   - Conntrack Netlink: support CTA_FILTER for flush.

   - Improve SCTP support in nfnetlink_queue.

   - Improve performance of large nftables flush transactions.

  Things we sprinkled into general kernel code:

   - selftests: support setting an "interpreter" for script files; make
     it easy to run as separate cases tests where one "interpreter" is
     fed various test descriptions (in our case packet sequences).

  Driver API:

   - Extend core and ethtool APIs to support many PHYs connected to a
     single interface (PHY topologies).

   - Extend cable diagnostics to specify whether Time Domain
     Reflectometry (TDR) or Active Link Cable Diagnostic (ALCD) was
     used.

   - Add library for implementing MAC-PHY Ethernet drivers for SPI
     devices compatible with Open Alliance 10BASE-T1x MAC-PHY Serial
     Interface (TC6) standard.

   - Add helpers to the PHY framework, for PHYs following the Open
     Alliance standards:
       - 1000BaseT1 link settings
       - cable test and diagnostics

   - Support listing / dumping all allocated RSS contexts.

   - Add configuration for frequency Embedded SYNC in DPLL, which
     magically embeds sync pulses into Ethernet signaling.

   - Ethernet high-speed NICs:
      - Broadcom (bnxt):
         - use better FW APIs for queue reset
