Joe Damato 18e2bf0edf eventpoll: Add epoll ioctl for epoll_params
Add an ioctl for getting and setting epoll_params. User programs can use
this ioctl to get and set the busy poll usec time, packet budget, and
prefer busy poll params for a specific epoll context.

Parameters are limited:
  - busy_poll_usecs is limited to <= s32_max
  - busy_poll_budget is limited to <= NAPI_POLL_WEIGHT by unprivileged
    users (!capable(CAP_NET_ADMIN))
  - prefer_busy_poll must be 0 or 1
  - __pad must be 0

Oliver Hartkopp c83c22ec14 can: canxl: add virtual CAN network identifier support
CAN XL data frames contain an 8-bit virtual CAN network identifier (VCID).
A VCID value of zero represents an 'untagged' CAN XL frame.

To receive and send these optional VCIDs via CAN_RAW sockets a new socket
option CAN_RAW_XL_VCID_OPTS is introduced to define/access VCID content:

- tx: set the outgoing VCID value by the kernel (one fixed 8-bit value)
- tx: pass through VCID values from the user space (e.g. for traffic replay)
- rx: apply VCID receive filter (value/mask) to be passed to the user space

With the 'tx pass through' option CAN_RAW_XL_VCID_TX_PASS all valid VCID
values can be sent, e.g. to replay full qualified CAN XL traffic.

The VCID value provided for the CAN_RAW_XL_VCID_TX_SET option will
override the VCID value in the struct canxl_frame.prio defined for
CAN_RAW_XL_VCID_TX_PASS when both flags are set.

With a rx_vcid_mask of zero all possible VCID values (0x00 - 0xFF) are
passed to the user space when the CAN_RAW_XL_VCID_RX_FILTER flag is set.
Without this flag only untagged CAN XL frames (VCID = 0x00) are delivered
to the user space (default).

The 8-bit VCID is stored inside the CAN XL prio element (only in CAN XL
frames!) to not interfere with other CAN content or the CAN filters
provided by the CAN_RAW sockets and kernel infrastruture.

Aahil Awatramani 240fd40552 bonding: Add independent control state machine
Add support for the independent control state machine per IEEE
802.1AX-2008 5.4.15 in addition to the existing implementation of the
coupled control state machine.

Introduces two new states, AD_MUX_COLLECTING and AD_MUX_DISTRIBUTING in
the LACP MUX state machine for separated handling of an initial
Collecting state before the Collecting and Distributing state. This
enables a port to be in a state where it can receive incoming packets
while not still distributing. This is useful for reducing packet loss when
a port begins distributing before its partner is able to collect.

Added new functions such as bond_set_slave_tx_disabled_flags and
bond_set_slave_rx_enabled_flags to precisely manage the port's collecting
and distributing states. Previously, there was no dedicated method to
disable TX while keeping RX enabled, which this patch addresses.

Note that the regular flow process in the kernel's bonding driver remains
unaffected by this patch. The extension requires explicit opt-in by the
user (in order to ensure no disruptions for existing setups) via netlink
support using the new bonding parameter coupled_control. The default value
for coupled_control is set to 1 so as to preserve existing behaviour.

Phil Sutter da5141bbe0 netfilter: nf_tables: Introduce NFT_TABLE_F_PERSIST
This companion flag to NFT_TABLE_F_OWNER requests the kernel to keep the
table around after the process has exited. It marks such table as
orphaned (by dropping OWNER flag but keeping PERSIST flag in place),
which opens it for other processes to manipulate. For the sake of
simplicity, PERSIST flag may not be altered though.

Min Li ea1cc3ee34 ptp: introduce PTP_CLOCK_EXTOFF event for the measured external offset
This change is for the PHC devices that can measure the phase offset
between PHC signal and the external signal, such as the 1PPS signal of
GNSS. Reporting PTP_CLOCK_EXTOFF to user space will be piggy-backed to
the existing ptp_extts_event so that application such as ts2phc can
poll the external offset the same way as extts. Hence, ts2phc can use
the offset to achieve the alignment between PHC and the external signal
by the help of either SW or HW filters.

   functionality from privileged system-wide daemons such as systemd
   through special mount options for userns-bound BPF fs to a trusted
   & unprivileged application. With addressed changes from Christian
   and Linus' reviews, from Andrii Nakryiko.

  There was a scheduler regression vs amdgpu which was reported in a few
  places and is now fixed. There was an i915 vs simpledrm problem
  resulting in black screens, that is reverted also.

  I'll be working on a proper nouveau fix, it kinda looks like one of

Andrii Nakryiko caf8f28e03 bpf: Add BPF token support to BPF_PROG_LOAD command
Add basic support of BPF token to BPF_PROG_LOAD. BPF_F_TOKEN_FD flag
should be set in prog_flags field when providing prog_token_fd.

Wire through a set of allowed BPF program types and attach types,
derived from BPF FS at BPF token creation time. Then make sure we
perform bpf_token_capable() checks everywhere where it's relevant.

Accept BPF token FD in BPF_BTF_LOAD command to allow BTF data loading
through delegated BPF token. BPF_F_TOKEN_FD flag has to be specified

field before, we also add btf_flags field.

BTF loading is a pretty straightforward operation, so as long as BPF
token is created with allow_cmds granting BPF_BTF_LOAD command, kernel
proceeds to parsing BTF data and creating BTF object.

Andrii Nakryiko 35f96de041 bpf: Introduce BPF token object
Add new kind of BPF kernel object, BPF token. BPF token is meant to
allow delegating privileged BPF functionality, like loading a BPF
program or creating a BPF map, from privileged process to a *trusted*
unprivileged process, all while having a good amount of control over which
privileged operations could be performed using provided BPF token.

This is achieved through mounting BPF FS instance with extra delegation
mount options, which determine what operations are delegatable, and also
constraining it to the owning user namespace (as mentioned in the
previous patch).

BPF token itself is just a derivative from BPF FS and can be created
through a new bpf() syscall command, BPF_TOKEN_CREATE, which accepts BPF
FS FD, which can be attained through open() API by opening BPF FS mount
point. Currently, BPF token "inherits" delegated command, map types,
prog type, and attach type bit sets from BPF FS as is. In the future,
having an BPF token as a separate object with its own FD, we can allow
to further restrict BPF token's allowable set of things either at the
creation time or after the fact, allowing the process to guard itself
further from unintentionally trying to load undesired kind of BPF
programs. But for now we keep things simple and just copy bit sets as is.

When BPF token is created from BPF FS mount, we take reference to the
BPF super block's owning user namespace, and then use that namespace for
checking all the {CAP_BPF, CAP_PERFMON, CAP_NET_ADMIN, CAP_SYS_ADMIN}
capabilities that are normally only checked against init userns (using
capable()), but now we check them using ns_capable() instead (if BPF
token is provided). See bpf_token_capable() for details.

Such setup means that BPF token in itself is not sufficient to grant BPF
functionality. User namespaced process has to *also* have necessary
combination of capabilities inside that user namespace. So while
previously CAP_BPF was useless when granted within user namespace, now
it gains a meaning and allows container managers and sys admins to have
a flexible control over which processes can and need to use BPF
functionality within the user namespace (i.e., container in practice).
And BPF FS delegation mount options and derived BPF tokens serve as
a per-container "flag" to grant overall ability to use bpf() (plus further
restrict on which parts of bpf() syscalls are treated as namespaced).

Note also, BPF_TOKEN_CREATE command itself requires ns_capable(CAP_BPF)
within the BPF FS owning user namespace, rounding up the ns_capable()
story of BPF token. Also creating BPF token in init user namespace is
currently not supported, given BPF token doesn't have any effect in init
user namespace anyways.

Kui-Feng Lee fcc2c1fb06 bpf: pass attached BTF to the bpf_struct_ops subsystem
Pass the fd of a btf from the userspace to the bpf() syscall, and then
convert the fd into a btf. The btf is generated from the module that
defines the target BPF struct_ops type.

In order to inform the kernel about the module that defines the target
struct_ops type, the userspace program needs to provide a btf fd for the
respective module's btf. This btf contains essential information on the
types defined within the module, including the target struct_ops type.

A btf fd must be provided to the kernel for struct_ops maps and for the bpf
programs attached to those maps.

In the case of the bpf programs, the attach_btf_obj_fd parameter is passed
as part of the bpf_attr and is converted into a btf. This btf is then
stored in the prog->aux->attach_btf field. Here, it just let the verifier
access attach_btf directly.

In the case of struct_ops maps, a btf fd is passed as value_type_btf_obj_fd
of bpf_attr. The bpf_struct_ops_map_alloc() function converts the fd to a
btf and stores it as st_map->btf. A flag BPF_F_VTYPE_BTF_OBJ_FD is added
for map_flags to indicate that the value of value_type_btf_obj_fd is set.

Kui-Feng Lee 1338b93346 bpf: pass btf object id in bpf_map_info.
Include btf object id (btf_obj_id) in bpf_map_info so that tools (ex:
bpftools struct_ops dump) know the correct btf from the kernel to look up
type information of struct_ops types.

Since struct_ops types can be defined and registered in a module. The
type information of a struct_ops type are defined in the btf of the
module defining it.  The userspace tools need to know which btf is for
the module defining a struct_ops type.

     - fix use-after-free in case the chunk length is not aligned to
       64K, this does not happen normally but has been reported on
       images converted from ext4
     - similar alignment check was missing with raid-stripe-tree

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

Linus Torvalds 86c4d58a99 iommufd for 6.8
This brings the first of three planned user IO page table invalidation
 operations:
 
  - IOMMU_HWPT_INVALIDATE allows invalidating the IOTLB integrated into the
    iommu itself. The Intel implementation will also generate an ATC
    invalidation to flush the device IOTLB as it unambiguously knows the
    device, but other HW will not.
 
 It goes along with the prior PR to implement userspace IO page tables (aka
 nested translation for VMs) to allow Intel to have full functionality for
 simple cases. An Intel implementation of the operation is provided.

Linus Torvalds 296455ade1 Char/Misc and other Driver changes for 6.8-rc1
Here is the big set of char/misc and other driver subsystem changes for
 6.8-rc1.  Lots of stuff in here, but first off, you will get a merge
 conflict in drivers/android/binder_alloc.c when merging this tree due to
 changing coming in through the -mm tree.
 
 The resolution of the merge issue can be found here:
 	https://lore.kernel.org/r/20231207134213.25631ae9@canb.auug.org.au
 or in a simpler patch form in that thread:
 	https://lore.kernel.org/r/ZXHzooF07LfQQYiE@google.com
 
 If there are issues with the merge of this file, please let me know.
 
 Other than lots of binder driver changes (as you can see by the merge
 conflicts) included in here are:
  - lots of iio driver updates and additions
  - spmi driver updates
  - eeprom driver updates
  - firmware driver updates
  - ocxl driver updates
  - mhi driver updates
  - w1 driver updates
  - nvmem driver updates
  - coresight driver updates
  - platform driver remove callback api changes
  - tags.sh script updates
  - bus_type constant marking cleanups
  - lots of other small driver updates
 
 All of these have been in linux-next for a while with no reported issues
 (other than the binder merge conflict.)

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Reserve ECAM so we don't assign it to PCI BARs; this works around
     bugs where BIOS included ECAM in a PNP0A03 host bridge window,
     didn't reserve it via a PNP0C02 motherboard device, and didn't
     allocate space for SR-IOV VF BARs (Bjorn Helgaas)

   - Add MMCONFIG/ECAM debug logging (Bjorn Helgaas)

   - Rename 'MMCONFIG' to 'ECAM' to match spec usage (Bjorn Helgaas)

   - Log device type (Root Port, Switch Port, etc) during enumeration
     (Bjorn Helgaas)

   - Log bridges before downstream devices so the dmesg order is more
     logical (Bjorn Helgaas)

   - Log resource names (BAR 0, VF BAR 0, bridge window, etc)
     consistently instead of a mix of names and "reg 0x10" (Puranjay
     Mohan, Bjorn Helgaas)

   - Fix 64GT/s effective data rate calculation to use 1b/1b encoding
     rather than the 8b/10b or 128b/130b used by lower rates (Ilpo
     Järvinen)

   - Use PCI_HEADER_TYPE_* instead of literals in x86, powerpc, SCSI
     lpfc (Ilpo Järvinen)

   - Clean up open-coded PCIBIOS return code mangling (Ilpo Järvinen)

  Resource management:

   - Restructure pci_dev_for_each_resource() to avoid computing the
     address of an out-of-bounds array element (the bounds check was
     performed later so the element was never actually *read*, but it's
     nicer to avoid even computing an out-of-bounds address) (Andy
     Shevchenko)

  Driver binding:

   - Convert pci-host-common.c platform .remove() callback to
     .remove_new() returning 'void' since it's not useful to return
     error codes here (Uwe Kleine-König)

   - Convert exynos, keystone, kirin from .remove() to .remove_new(),
     which returns void instead of int (Uwe Kleine-König)

   - Drop unused struct pci_driver.node member (Mathias Krause)

  Virtualization:

   - Add ACS quirk for more Zhaoxin Root Ports (LeoLiuoc)

  Error handling:

   - Log AER errors as "Correctable" (not "Corrected") or
     "Uncorrectable" to match spec terminology (Bjorn Helgaas)

   - Decode Requester ID when no error info found instead of printing
     the raw hex value (Bjorn Helgaas)

  Endpoint framework:

   - Use a unique test pattern for each BAR in the pci_endpoint_test to
     make it easier to debug address translation issues (Niklas Cassel)

  Broadcom STB PCIe controller driver:

   - Add DT property "brcm,clkreq-mode" and driver support for different
     CLKREQ# modes to make ASPM L1.x states possible (Jim Quinlan)

  Freescale Layerscape PCIe controller driver:

   - Add suspend/resume support for Layerscape LS1043a and LS1021a,
     including software-managed PME_Turn_Off and transitions between L0,
     L2/L3_Ready Link states (Frank Li)

  MediaTek PCIe controller driver:

   - Clear MSI interrupt status before handler to avoid missing MSIs
     that occur after the handler (qizhong cheng)

  MediaTek PCIe Gen3 controller driver:

   - Update mediatek-gen3 translation window setup to handle MMIO space
     that is not a power of two in size (Jianjun Wang)

  Qualcomm PCIe controller driver:

   - Increase qcom iommu-map maxItems to accommodate SDX55 (five
     entries) and SDM845 (sixteen entries) (Krzysztof Kozlowski)

   - Describe qcom,pcie-sc8180x clocks and resets accurately (Krzysztof
     Kozlowski)

   - Describe qcom,pcie-sm8150 clocks and resets accurately (Krzysztof
     Kozlowski)

   - Correct the qcom "reset-name" property, previously incorrectly
     called "reset-names" (Krzysztof Kozlowski)

   - Document qcom,pcie-sm8650, based on qcom,pcie-sm8550 (Neil
     Armstrong)

  Renesas R-Car PCIe controller driver:

   - Replace of_device.h with explicit of.h include to untangle header
     usage (Rob Herring)

   - Add DT and driver support for optional miniPCIe 1.5v and 3.3v
     regulators on KingFisher (Wolfram Sang)

  SiFive FU740 PCIe controller driver:

   - Convert fu740 CONFIG_PCIE_FU740 dependency from SOC_SIFIVE to
     ARCH_SIFIVE (Conor Dooley)

  Synopsys DesignWare PCIe controller driver:

   - Align iATU mapping for endpoint MSI-X (Niklas Cassel)

   - Drop "host_" prefix from struct dw_pcie_host_ops members (Yoshihiro
     Shimoda)

   - Drop "ep_" prefix from struct dw_pcie_ep_ops members (Yoshihiro
     Shimoda)

   - Rename struct dw_pcie_ep_ops.func_conf_select() to
     .get_dbi_offset() to be more descriptive (Yoshihiro Shimoda)

   - Add Endpoint DBI accessors to encapsulate offset lookups (Yoshihiro
     Shimoda)

  TI J721E PCIe driver:

   - Add j721e DT and driver support for 'num-lanes' for devices that
     support x1, x2, or x4 Links (Matt Ranostay)

   - Add j721e DT compatible strings and driver support for j784s4 (Matt
     Ranostay)

   - Make TI J721E Kconfig depend on ARCH_K3 since the hardware is
     specific to those TI SoC parts (Peter Robinson)

  TI Keystone PCIe controller driver:

   - Hold power management references to all PHYs while enabling them to
     avoid a race when one provides clocks to others (Siddharth
     Vadapalli)

  Xilinx XDMA PCIe controller driver:

   - Remove redundant dev_err(), since platform_get_irq() and
     platform_get_irq_byname() already log errors (Yang Li)

   - Fix uninitialized symbols in xilinx_pl_dma_pcie_setup_irq()
     (Krzysztof Wilczyński)

   - Fix xilinx_pl_dma_pcie_init_irq_domain() error return when
     irq_domain_add_linear() fails (Harshit Mogalapalli)

  MicroSemi Switchtec management driver:

   - Do dma_mrpc cleanup during switchtec_pci_remove() to match its devm
     ioremapping in switchtec_pci_probe(). Previously the cleanup was
     done in stdev_release(), which used stale pointers if stdev->cdev
     happened to be open when the PCI device was removed (Daniel
     Stodden)

  Miscellaneous:

   - Convert interrupt terminology from "legacy" to "INTx" to be more
     specific and match spec terminology (Damien Le Moal)

   - In dw-xdata-pcie, pci_endpoint_test, and vmd, replace usage of
     deprecated ida_simple_*() API with ida_alloc() and ida_free()
     (Christophe JAILLET)"

Linus Torvalds 09d1c6a80f Generic:
- Use memdup_array_user() to harden against overflow.
 
 - Unconditionally advertise KVM_CAP_DEVICE_CTRL for all architectures.
 
 - Clean up Kconfigs that all KVM architectures were selecting
 
 - New functionality around "guest_memfd", a new userspace API that
   creates an anonymous file and returns a file descriptor that refers
   to it.  guest_memfd files are bound to their owning virtual machine,
   cannot be mapped, read, or written by userspace, and cannot be resized.
   guest_memfd files do however support PUNCH_HOLE, which can be used to
   switch a memory area between guest_memfd and regular anonymous memory.
 
 - New ioctl KVM_SET_MEMORY_ATTRIBUTES allowing userspace to specify
   per-page attributes for a given page of guest memory; right now the
   only attribute is whether the guest expects to access memory via
   guest_memfd or not, which in Confidential SVMs backed by SEV-SNP,
   TDX or ARM64 pKVM is checked by firmware or hypervisor that guarantees
   confidentiality (AMD PSP, Intel TDX module, or EL2 in the case of pKVM).
 
 x86:
 
 - Support for "software-protected VMs" that can use the new guest_memfd
   and page attributes infrastructure.  This is mostly useful for testing,
   since there is no pKVM-like infrastructure to provide a meaningfully
   reduced TCB.
 
 - Fix a relatively benign off-by-one error when splitting huge pages during
   CLEAR_DIRTY_LOG.
 
 - Fix a bug where KVM could incorrectly test-and-clear dirty bits in non-leaf
   TDP MMU SPTEs if a racing thread replaces a huge SPTE with a non-huge SPTE.
 
 - Use more generic lockdep assertions in paths that don't actually care
   about whether the caller is a reader or a writer.
 
 - let Xen guests opt out of having PV clock reported as "based on a stable TSC",
   because some of them don't expect the "TSC stable" bit (added to the pvclock
   ABI by KVM, but never set by Xen) to be set.
 
 - Revert a bogus, made-up nested SVM consistency check for TLB_CONTROL.
 
 - Advertise flush-by-ASID support for nSVM unconditionally, as KVM always
   flushes on nested transitions, i.e. always satisfies flush requests.  This
   allows running bleeding edge versions of VMware Workstation on top of KVM.
 
 - Sanity check that the CPU supports flush-by-ASID when enabling SEV support.
 
 - On AMD machines with vNMI, always rely on hardware instead of intercepting
   IRET in some cases to detect unmasking of NMIs
 
 - Support for virtualizing Linear Address Masking (LAM)
 
 - Fix a variety of vPMU bugs where KVM fail to stop/reset counters and other state
   prior to refreshing the vPMU model.
 
 - Fix a double-overflow PMU bug by tracking emulated counter events using a
   dedicated field instead of snapshotting the "previous" counter.  If the
   hardware PMC count triggers overflow that is recognized in the same VM-Exit
   that KVM manually bumps an event count, KVM would pend PMIs for both the
   hardware-triggered overflow and for KVM-triggered overflow.
 
 - Turn off KVM_WERROR by default for all configs so that it's not
   inadvertantly enabled by non-KVM developers, which can be problematic for
   subsystems that require no regressions for W=1 builds.
 
 - Advertise all of the host-supported CPUID bits that enumerate IA32_SPEC_CTRL
   "features".
 
 - Don't force a masterclock update when a vCPU synchronizes to the current TSC
   generation, as updating the masterclock can cause kvmclock's time to "jump"
   unexpectedly, e.g. when userspace hotplugs a pre-created vCPU.
 
 - Use RIP-relative address to read kvm_rebooting in the VM-Enter fault paths,
   partly as a super minor optimization, but mostly to make KVM play nice with
   position independent executable builds.
 
 - Guard KVM-on-HyperV's range-based TLB flush hooks with an #ifdef on
   CONFIG_HYPERV as a minor optimization, and to self-document the code.
 
 - Add CONFIG_KVM_HYPERV to allow disabling KVM support for HyperV "emulation"
   at build time.
 
 ARM64:
 
 - LPA2 support, adding 52bit IPA/PA capability for 4kB and 16kB
   base granule sizes. Branch shared with the arm64 tree.
 
 - Large Fine-Grained Trap rework, bringing some sanity to the
   feature, although there is more to come. This comes with
   a prefix branch shared with the arm64 tree.
 
 - Some additional Nested Virtualization groundwork, mostly
   introducing the NV2 VNCR support and retargetting the NV
   support to that version of the architecture.
 
 - A small set of vgic fixes and associated cleanups.
 
 Loongarch:
 
 - Optimization for memslot hugepage checking
 
 - Cleanup and fix some HW/SW timer issues
 
 - Add LSX/LASX (128bit/256bit SIMD) support
 
 RISC-V:
 
 - KVM_GET_REG_LIST improvement for vector registers
 
 - Generate ISA extension reg_list using macros in get-reg-list selftest
 
 - Support for reporting steal time along with selftest
 
 s390:
 
 - Bugfixes
 
 Selftests:
 
 - Fix an annoying goof where the NX hugepage test prints out garbage
   instead of the magic token needed to run the test.
 
 - Fix build errors when a header is delete/moved due to a missing flag
   in the Makefile.
 
 - Detect if KVM bugged/killed a selftest's VM and print out a helpful
   message instead of complaining that a random ioctl() failed.
 
 - Annotate the guest printf/assert helpers with __printf(), and fix the
   various bugs that were lurking due to lack of said annotation.
 
 There are two non-KVM patches buried in the middle of guest_memfd support:
 
   fs: Rename anon_inode_getfile_secure() and anon_inode_getfd_secure()
   mm: Add AS_UNMOVABLE to mark mapping as completely unmovable
 
 The first is small and mostly suggested-by Christian Brauner; the second
 a bit less so but it was written by an mm person (Vlastimil Babka).

     instead of the magic token needed to run the test.

   - Fix build errors when a header is delete/moved due to a missing
     flag in the Makefile.

   - Detect if KVM bugged/killed a selftest's VM and print out a helpful
     message instead of complaining that a random ioctl() failed.

   - Annotate the guest printf/assert helpers with __printf(), and fix
     the various bugs that were lurking due to lack of said annotation"

Linus Torvalds 7912a6391f sound updates for 6.8-rc1
It was a clam development cycle.  There were an ALSA core extension
 for subformat PCM bits and a few ASoC core changes to support N:M
 mappings, while the most of remaining changes are driver-specific.
 
 Core:
 - API extensions for properly limiting PCM format bits via subformat
 - Enhanced support for N:M CPU:CODEC mappings in the core and in
   audio-graph-card2
 
 ASoC:
 - Lots of SOF updates: fallback support to older IPC versions,
   notification on control changes with IPC4.
   Also supports for ACPI parse for the ES83xx driver that reduces
   quirks.
 - Device tree support for describing parts of the card which can be
   active over suspend (for very low power playback or wake word use
   cases)
 - Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
   SM8250, SM8550, SM8650 and X1E80100
 - Drop of Freescale MPC8610 code that is no longer supported
 
 HD-audio:
 - More CS35L41 codec extensions for Dell, HP and Lenovo models
 - TAS2781 codec extensions for Lenovo and co
 - New PCM subformat supports
 
 Others:
 - More enhancement for Scarlett2 USB mixer support

Merge tag 'drm-next-2024-01-10' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "This contains two major new drivers:

   - imagination is a first driver for Imagination Technologies devices,
     it only covers very specific devices, but there is hope to grow it

   - xe is a reboot of the i915 GPU (shares display) side using a more
     upstream focused development model, and trying to maximise code
     sharing. It's not enabled for any hw by default, and will hopefully
     get switched on for Intel's Lunarlake.

  This also drops a bunch of the old UMS ioctls. It's been dead long
  enough.

  amdgpu has a bunch of new color management code that is being used in
  the Steam Deck.

  amdgpu also has a new ACPI WBRF interaction to help avoid radio
  interference.

  Detailed summary:

  new drivers:
   - imagination - new driver for Imagination Technologies GPU

Qu Wenruo 173431b274 btrfs: defrag: reject unknown flags of btrfs_ioctl_defrag_range_args
Add extra sanity check for btrfs_ioctl_defrag_range_args::flags.

This is not really to enhance fuzzing tests, but as a preparation for
future expansion on btrfs_ioctl_defrag_range_args.

In the future we're going to add new members, allowing more fine tuning
for btrfs defrag.  Without the -ENONOTSUPP error, there would be no way
to detect if the kernel supports those new defrag features.

 This time around there's only a single line update to the core, so
