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.

  Apart from the above, there is a usual collection of assorted fixes
  and code cleanups in many places and there are tooling updates.

  Specifics:

   - Remove LATENCY_MULTIPLIER from cpufreq (Qais Yousef)

   - Add support for Granite Rapids and Sierra Forest in OOB mode to the

Merge tag 'for-linus-non-x86' of git://git.kernel.org/pub/scm/virt/kvm/kvm

Pull kvm updates from Paolo Bonzini:
 "These are the non-x86 changes (mostly ARM, as is usually the case).
  The generic and x86 changes will come later"

  ARM:

   - New Stage-2 page table dumper, reusing the main ptdump
     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

   - Fix multiple cases where KVM/arm64 doesn't correctly handle the
     guest trying to use a GICv3 that wasn't advertised

   - Remove REG_HIDDEN_USER from the sysreg infrastructure, making
     things little simpler

   - 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

   - Allow legacy PMU access from guest

   - Fix to allow hpmcounter31 from the guest"

9410645520 Networking changes for 6.12. 
The zero-copy changes are relatively significant, but regression risk
 should be contained. The feature needs to be used to cause trouble.
 The new code did trigger a PowerPC64 bug with GCC 14:
 
   https://lore.kernel.org/netdev/20240913125302.0a06b4c7@canb.auug.org.au/
 
 a fix for which Michael will bring via his tree:
 
   https://lore.kernel.org/all/87jzffq9ge.fsf@mail.lhotse/
 
 Unideal, not sure if you'll be willing to pull without that fix but
 since we caught this recently I figured we'll defer to you during
 the MW instead of trying to fix it cross-tree.
 
 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.
 
 Device drivers
 --------------
 
  - Ethernet high-speed NICs:
    - Broadcom (bnxt):
      - use better FW APIs for queue reset
      - support QOS and TPID settings for the SR-IOV VLAN

Merge tag 'net-next-6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

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.

2ba0d8947e cifs: Recognize SFU socket type 
SFU since its (first) version 3.0 supports AF_LOCAL sockets and stores them
on filesytem as system file with one zero byte. Add support for detecting
this SFU socket type into cifs_sfu_type() function.

With this change cifs_sfu_type() would correctly detect all special file
types created by SFU: fifo, socket, symlink, block and char.

bb68327053 cifs: Put explicit zero byte into SFU block/char types 
SFU types IntxCHR and IntxBLK are 8 bytes with zero as last byte. Make it
explicit in memcpy and memset calls, so the zero byte is visible in the
code (and not hidden as string trailing nul byte).

It is important for reader to show the last byte for block and char types
because it differs from the last byte of symlink type (which has it 0x01).

Also it is important to show that the type is not nul-term string, but
rather 8 bytes (with some printable bytes).

cf2ce67345 cifs: Add support for reading SFU symlink location 
Currently when sfu mount option is specified then CIFS can recognize SFU
symlink, but is not able to read symlink target location. readlink()
syscall just returns that operation is not supported.

Implement this missing functionality in cifs_sfu_type() function. Read
target location of SFU-style symlink, parse it and fill into fattr's
cf_symlink_target member.

SFU-style symlink is file which has system attribute set and file content
is buffer "IntxLNK\1" (8th byte is 0x01) followed by the target location
encoded in little endian UCS-2/UTF-16. This format was introduced in
Interix 3.0 subsystem, as part of the Microsoft SFU 3.0 and is used also by
all later versions. Previous versions had no symlink support.

94ae8c3fee smb: client: compress: LZ77 code improvements cleanup 
- Check data compressibility with some heuristics (copied from
  btrfs):
  - should_compress() final decision is is_compressible(data)

- Cleanup compress/lz77.h leaving only lz77_compress() exposed:
  - Move parts to compress/lz77.c, while removing the rest of it
    because they were either unused, used only once, were
    implemented wrong (thanks to David Howells for the help)

- Updated the compression parameters (still compatible with
  Windows implementation) trading off ~20% compression ratio
  for ~40% performance:
  - min match len: 3 -> 4
  - max distance: 8KiB -> 1KiB
  - hash table type: u32 * -> u64 *

Known bugs:
This implementation currently works fine in general, but breaks with
some payloads used during testing.  Investigation ongoing, to be
fixed in a next commit.

be461814aa net/mlx5: HWS, check the correct variable in hws_send_ring_alloc_sq() 
There is a copy and paste bug so this code checks "sq->dep_wqe" where
"sq->wr_priv" was intended.  It could result in a NULL pointer
dereference.

869acb874f * Raw NAND changes 
The use of for_each_child_of_node_scoped() has been spread into the
 subsystem drivers. Aside from that, a couple of exit path have been
 fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply
 with up-to-date partition descriptions and as always there is a load of
 small and misc fixes.
 
 * SPI-NAND changes
 
 The most impacting series this cycle is bringing support for continuous
 reads in the SPI-NAND subsystem. This is a feature already merged in the
 raw NAND subsystem which allows optimizing the internal fetch times in
 the chip while reading sequential pages within an eraseblock. For now
 only Macronix NANDs benefit from this feature. While we are talking
 about Macronix, some of their chip need an explicit action for selecting
 a different plane, and support for it has also been brought.
 
 The bitflip threshold has also been set to the same arbitrary level as
 in the raw NAND subsystem to optimize wear leveling decisions, and
 finally support for a new Winbond chip has been added.

 - Fix a NULL dereference in probe path for flashes without a name. The
   probe path tries to access the name without checking its existence

9d70f3fec1 Revert "KVM: VMX: Always honor guest PAT on CPUs that support self-snoop" 
This reverts commit 377b2f359d.

This caused a regression with the bochsdrm driver, which used ioremap()
instead of ioremap_wc() to map the video RAM.  After the commit, the
WB memory type is used without the IGNORE_PAT, resulting in the slower
UC memory type.  In fact, UC is slow enough to basically cause guests
to not boot... but only on new processors such as Sapphire Rapids and
Cascade Lake.  Coffee Lake for example works properly, though that might
also be an effect of being on a larger, more NUMA system.

The driver has been fixed but that does not help older guests.  Until we
figure out whether Cascade Lake and newer processors are working as
intended, revert the commit.  Long term we might add a quirk, but the
details depend on whether the processors are working as intended: for
example if they are, the quirk might reference bochs-compatible devices,
e.g. in the name and documentation, so that userspace can disable the
quirk by default and only leave it enabled if such a device is being
exposed to the guest.

If instead this is actually a bug in CLX+, then the actions we need to
take are different and depend on the actual cause of the bug.
