The ACPI processor driver is not currently enabled for RISC-V.
This is required to enable CPU related functionalities like
LPI and CPPC. Hence, enable ACPI_PROCESSOR for RISC-V.

Pull CXL updates from Dan Williams:
 "CXL has mechanisms to enumerate the performance characteristics of
  memory devices. Those mechanisms allow Linux to build the equivalent
  of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
  capability is necessary because static ACPI can not represent dynamic
  CXL configurations (and reconfigurations).

  So, building on the v6.8 work to add "Quality of Service" enumeration,
  this update plumbs CXL "access coordinates" (read/write access latency
  and bandwidth) in all the same places that ACPI HMAT feeds similar
  data. Follow-on patches from the -mm side can then use that data to
  feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
  drivers/base/.

  The other feature update this cycle is support for CXL error injection
  via the ACPI EINJ module. That facility enables injection of bus
  protocol errors provided the user knows the magic address values to
  insert in the interface. To hide that magic, and make this easier to
  use, new error injection attributes were added to CXL debugfs. That
  interface injects the errors relative to a CXL object rather than
  require user tooling to know how to lookup and inject RCRB (Root
  Complex Register Block) addresses into the raw EINJ debugfs interface.
  It received some helpful review comments from Tony, but no explicit
  acks from the ACPI side. The primary user visible change for existing
  EINJ users is that they may find that einj.ko was already loaded by
  cxl_core.ko. Previously, einj.ko was only loaded on demand.

  The usual collection of miscellaneous cleanups are also present this
  cycle.

  Summary:

   - Supplement ACPI HMAT reported memory performance with native CXL
     memory performance enumeration

   - Add support for CXL error injection via the ACPI EINJ mechanism

   - Cleanup CXL DOE and CDAT integration

   - Miscellaneous cleanups and fixes"

This patch enhances the documentation for the ACPI power management
functions related to system suspend and hibernation.

This includes the use of kernel-doc style comments which provide
developers with clearer guidance on the usage and expectations of
these functions.

Pull sound updates from Takashi Iwai:
 "This was a relatively calm development cycle. Most of changes are
  rather small device-specific fixes and enhancements. The only
  significant changes in ALSA core are code refactoring with the recent
  cleanup infrastructure, which should bring no functionality changes.
  Some highlights below:

  Core:
   - Lots of cleanups in ALSA core code with automatic kfree cleanup and
     locking guard macros
   - New ALSA core kunit test

  ASoC:
   - SoundWire support for AMD ACP 6.3 systems
   - Support for reporting version information for AVS firmware
   - Support DSPless mode for Intel Soundwire systems
   - Support for configuring CS35L56 amplifiers using EFI calibration
     data
   - Log which component is being operated on as part of power
     management trace events.
   - Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x

  HD- and USB-audio:
   - More Cirrus HD-audio codec support
   - TAS2781 HD-audio codec fixes
   - Scarlett2 mixer fixes

  Others:
   - Enhancement of virtio driver for audio control supports

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Consolidate interrupt related code in irq.c (Ilpo Järvinen)

   - Reduce kernel size by replacing sysfs resource macros with
     functions (Ilpo Järvinen)

   - Reduce kernel size by compiling sysfs support only when
     CONFIG_SYSFS=y (Lukas Wunner)

   - Avoid using Extended Tags on 3ware-9650SE Root Port to work around
     an apparent hardware defect (Jörg Wedekind)

  Resource management:

   - Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)

   - Move pci_iomap.c and other PCI-specific devres code to drivers/pci
     (Philipp Stanner)

   - Consolidate PCI devres code in devres.c (Philipp Stanner)

  Power management:

   - Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
     know how to return correctly to D0, and remove previous quirk that
     wasn't as specific (Daniel Drake)

   - Allow runtime PM when the driver enables it but doesn't need any
     runtime PM callbacks (Raag Jadav)

   - Drain runtime-idle callbacks before driver removal to avoid races
     between .remove() and .runtime_idle(), which caused intermittent
     page faults when the rtsx .runtime_idle() accessed registers that
     its .remove() had already unmapped (Rafael J. Wysocki)

  Virtualization:

   - Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
     with VFIO, e.g., for professional audio software on many Apple
     machines, at the cost of leaking state between VMs (Edmund Raile)

  Error handling:

   - Print all logged TLP Prefixes, not just the first, after AER or DPC
     errors (Ilpo Järvinen)

   - Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
     still don't advertise a legal size (Paul Menzel)

   - Ignore expected DPC Surprise Down errors on hot removal (Smita
     Koralahalli)

   - Block runtime suspend while handling AER errors to avoid races that
     prevent the device form being resumed from D3hot (Stanislaw
     Gruszka)

  Peer-to-peer DMA:

   - Use atomic XA allocation in RCU read section (Christophe JAILLET)

  ASPM:

   - Collect bits of ASPM-related code that we need even without
     CONFIG_PCIEASPM into aspm.c (David E. Box)

   - Save/restore L1 PM Substates config for suspend/resume (David E.
     Box)

   - Update save_save when ASPM config is changed, so a .slot_reset()
     during error recovery restores the changed config, not the
     .probe()-time config (Vidya Sagar)

  Endpoint framework:

   - Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)

   - Clean up endpoint BAR descriptions (Niklas Cassel)

   - Fix ntb_register_device() name leak in error path (Yang Yingliang)

   - Return actual error code for pci_vntb_probe() failure (Yang
     Yingliang)

  Broadcom STB PCIe controller driver:

   - Fix MDIO write polling, which previously never waited for
     completion (Jonathan Bell)

  Cadence PCIe endpoint driver:

   - Clear the ARI "Next Function Number" of last function (Jasko-EXT
     Wojciech)

  Freescale i.MX6 PCIe controller driver:

   - Simplify by replacing switch statements with function pointers for
     different hardware variants (Frank Li)

   - Simplify by using clk_bulk*() API (Frank Li)

   - Remove redundant DT clock and reg/reg-name details (Frank Li)

   - Add i.MX95 DT and driver support for both Root Complex and Endpoint
     mode (Frank Li)

  Microsoft Hyper-V host bridge driver:

   - Reduce memory usage by limiting ring buffer size to 16KB instead of
     4 pages (Michael Kelley)

  Qualcomm PCIe controller driver:

   - Add X1E80100 DT and driver support (Abel Vesa)

   - Add DT 'required-opps' for SoCs that require a minimum performance
     level (Johan Hovold)

   - Make DT 'msi-map-mask' optional, depending on how MSI interrupts
     are mapped (Johan Hovold)

   - Disable ASPM L0s for sc8280xp, sa8540p and sa8295p because the PHY
     configuration isn't tuned correctly for L0s (Johan Hovold)

   - Split dt-binding qcom,pcie.yaml into qcom,pcie-common.yaml and
     separate files for SA8775p, SC7280, SC8180X, SC8280XP, SM8150,
     SM8250, SM8350, SM8450, SM8550 for easier reviewing (Krzysztof
     Kozlowski)

   - Enable BDF to SID translation by disabling bypass mode (Manivannan
     Sadhasivam)

   - Add endpoint MHI support for Snapdragon SA8775P SoC (Mrinmay
     Sarkar)

  Synopsys DesignWare PCIe controller driver:

   - Allocate 64-bit MSI address if no 32-bit address is available (Ajay
     Agarwal)

   - Fix endpoint Resizable BAR to actually advertise the required 1MB
     size (Niklas Cassel)

  MicroSemi Switchtec management driver:

   - Release resources if the .probe() fails (Christophe JAILLET)

  Miscellaneous:

   - Make pcie_port_bus_type const (Ricardo B. Marliere)"
