Pull CPU speculation fixes from Borislav Petkov:
 "Add the mitigation logic for Transient Scheduler Attacks (TSA)

  TSA are new aspeculative side channel attacks related to the execution
  timing of instructions under specific microarchitectural conditions.
  In some cases, an attacker may be able to use this timing information
  to infer data from other contexts, resulting in information leakage.

  Add the usual controls of the mitigation and integrate it into the
  existing speculation bugs infrastructure in the kernel"

3719a04a80 Merge tag 'pci-v6.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Print the actual delay time in pci_bridge_wait_for_secondary_bus()
     instead of assuming it was 1000ms (Wilfred Mallawa)

   - Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
     devices', which broke resume from system sleep on AMD platforms and
     has been fixed by other commits (Lukas Wunner)

  Resource management:

   - Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
     and unnecessary (Philipp Stanner)

   - Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
     and related flags since all uses have been removed (Philipp
     Stanner)

   - Rework devres 'request' functions so they are no longer 'hybrid',
     i.e., their behavior no longer depends on whether
     pcim_enable_device or pci_enable_device() was used, and remove
     related code (Philipp Stanner)

   - Warn (not BUG()) about failure to assign optional resources (Ilpo
     Järvinen)

  Error handling:

   - Log the DPC Error Source ID only when it's actually valid (when
     ERR_FATAL or ERR_NONFATAL was received from a downstream device)
     and decode into bus/device/function (Bjorn Helgaas)

   - Determine AER log level once and save it so all related messages
     use the same level (Karolina Stolarek)

   - Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
     Errors (Karolina Stolarek)

   - Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
     controls on interval and burst count, to avoid flooding logs and
     RCU stall warnings (Jon Pan-Doh)

  Power management:

   - Increment PM usage counter when probing reset methods so we don't
     try to read config space of a powered-off device (Alex Williamson)

   - Set all devices to D0 during enumeration to ensure ACPI opregion is
     connected via _REG (Mario Limonciello)

  Power control:

   - Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
     the filename paths. Retain old deprecated symbols for
     compatibility, except for the pwrctrl slot driver
     (PCI_PWRCTRL_SLOT) (Johan Hovold)

   - When unregistering pwrctrl, cancel outstanding rescan work before
     cleaning up data structures to avoid use-after-free issues (Brian
     Norris)

  Bandwidth control:

   - Simplify link bandwidth controller by replacing the count of Link
     Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
     flag (Ilpo Järvinen)

   - Update the Link Speed after retraining, since the Link Speed may
     have changed (Ilpo Järvinen)

  PCIe native device hotplug:

   - Ignore Presence Detect Changed caused by DPC.

     pciehp already ignores Link Down/Up events caused by DPC, but on
     slots using in-band presence detect, DPC causes a spurious Presence
     Detect Changed event (Lukas Wunner)

   - Ignore Link Down/Up caused by Secondary Bus Reset.

     On hotplug ports using in-band presence detect, the reset causes a
     Presence Detect Changed event, which mistakenly caused teardown and
     re-enumeration of the device. Drivers may need to annotate code
     that resets their device (Lukas Wunner)

  Virtualization:

   - Add an ACS quirk for Loongson Root Ports that don't advertise ACS
     but don't allow peer-to-peer transactions between Root Ports; the
     quirk allows each Root Port to be in a separate IOMMU group (Huacai
     Chen)

  Endpoint framework:

   - For fixed-size BARs, retain both the actual size and the possibly
     larger size allocated to accommodate iATU alignment requirements
     (Jerome Brunet)

   - Simplify ctrl/SPAD space allocation and avoid allocating more space
     than needed (Jerome Brunet)

   - Correct MSI-X PBA offset calculations for DesignWare and Cadence
     endpoint controllers (Niklas Cassel)

   - Align the return value (number of interrupts) encoding for
     pci_epc_get_msi()/pci_epc_ops::get_msi() and
     pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)

   - Align the nr_irqs parameter encoding for
     pci_epc_set_msi()/pci_epc_ops::set_msi() and
     pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)

  Common host controller library:

   - Convert pci-host-common to a library so platforms that don't need
     native host controller drivers don't need to include these helper
     functions (Manivannan Sadhasivam)

  Apple PCIe controller driver:

   - Extract ECAM bridge creation helper from pci_host_common_probe() to
     separate driver-specific things like MSI from PCI things (Marc
     Zyngier)

   - Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
     varying capabilities (Marc Zyngier)

   - Skip ports disabled in DT when setting up ports (Janne Grunau)

   - Add t6020 compatible string (Alyssa Rosenzweig)

   - Add T602x PCIe support (Hector Martin)

   - Directly set/clear INTx mask bits because T602x dropped the
     accessors that could do this without locking (Marc Zyngier)

   - Move port PHY registers to their own reg items to accommodate
     T602x, which moves them around; retain default offsets for existing
     DTs that lack phy%d entries with the reg offsets (Hector Martin)

   - Stop polling for core refclk, which doesn't work on T602x and the
     bootloader has already done anyway (Hector Martin)

   - Use gpiod_set_value_cansleep() when asserting PERST# in probe
     because we're allowed to sleep there (Hector Martin)

  Cadence PCIe controller driver:

   - Drop a runtime PM 'put' to resolve a runtime atomic count underflow
     (Hans Zhang)

   - Make the cadence core buildable as a module (Kishon Vijay Abraham I)

   - Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
     loadable drivers when they are removed (Siddharth Vadapalli)

  Freescale i.MX6 PCIe controller driver:

   - Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
     (Richard Zhu)

   - Remove redundant dw_pcie_wait_for_link() from
     imx_pcie_start_link(); since the DWC core does this, imx6 only
     needs it when retraining for a faster link speed (Richard Zhu)

   - Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)

   - Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
     some cases, the controller can't exit 'L23 Ready' through Beacon or
     PERST# deassertion (Richard Zhu)

   - Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
     controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
     GT/s, causing timeouts in L1 (Richard Zhu)

   - Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)

   - Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)

  Mobiveil PCIe controller driver:

   - Return bool (not int) for link-up check in
     mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
     Zhang)

  NVIDIA Tegra194 PCIe controller driver:

   - Create debugfs directory for 'aspm_state_cnt' only when
     CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
     Zhang)

  Qualcomm PCIe controller driver:

   - Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
     equalization presets (Krishna Chaitanya Chundru)

   - Read Maximum Link Width from the Link Capabilities register if DT
     lacks 'num-lanes' property (Krishna Chaitanya Chundru)

   - Add Physical Layer 64 GT/s Capability ID and register offsets for
     8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
     Chundru)

   - Add generic dwc support for configuring lane equalization presets
     (Krishna Chaitanya Chundru)

   - Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)

  Renesas R-Car PCIe controller driver:

   - Describe endpoint BAR 4 as being fixed size (Jerome Brunet)

   - Document how to obtain R-Car V4H (r8a779g0) controller firmware
     (Yoshihiro Shimoda)

  Rockchip PCIe controller driver:

   - Reorder rockchip_pci_core_rsts because
     reset_control_bulk_deassert() deasserts in reverse order, to fix a
     link training regression (Jensen Huang)

   - Mark RK3399 as being capable of raising INTx interrupts (Niklas
     Cassel)

  Rockchip DesignWare PCIe controller driver:

   - Check only PCIE_LINKUP, not LTSSM status, to determine whether the
     link is up (Shawn Lin)

   - Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
     for Root Complex and Endpoint modes (Shawn Lin)

   - Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
     of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
     resets non-sticky registers (Shawn Lin)

   - Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
     (Diederik de Haas)

  Synopsys DesignWare PCIe controller driver:

   - Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
     more robust; this will not affect the intended link width if all
     lanes are functional (Wenbin Yao)

   - Return bool (not int) for link-up check in dw_pcie_ops.link_up()
     and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
     keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
     tegra194, uniphier, visconti (Hans Zhang)

   - Add debugfs support for exposing DWC device-specific PTM context
     (Manivannan Sadhasivam)

   - Make j721e buildable as a loadable and removable module (Siddharth
     Vadapalli)

   - Fix j721e host/endpoint dependencies that result in link failures
     in some configs (Arnd Bergmann)

  Device tree bindings:

   - Add qcom DT binding for 'global' interrupt (PCIe controller and
     link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
     sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan

Pull LED updates from Lee Jones:
 "LED Triggers:
   - Allow writing "default" to the sysfs 'trigger' attribute to set an
     LED to its default trigger
   - If the default trigger is "none", writing "default" will remove the
     current trigger
   - Updated sysfs ABI documentation for the new "default" trigger
     functionality

     with 'V4L2_CID_FLASH_DURATION'

  Texas Instruments TPS6131x:
   - Add a new driver for the TPS61310/TPS61311 flash LED controllers
   - The driver supports the device's three constant-current sinks for
     flash and torch modes

  LED Core:
   - Prevent potential 'snprintf()' truncations in LED names by checking
     for buffer overflows

  ChromeOS EC LEDs:
   - Avoid a -Wflex-array-member-not-at-end GCC warning by replacing an
     on-stack flexible structure definition with a utility function call

  Multicolor LEDs:
   - Fix issue where setting multi_intensity while software blinking is
     active could stop blinking

  PCA955x LEDs:
   - Avoid potential buffer overflow when creating default labels by
     changing a field's type to 'u8' and updating format specifiers

  PCA995x LEDs:
   - Fix a typo (stray space) in an 'of_device_id' entry in the
     'pca995x_of_match' table

  Kconfig:
   - Prevent LED drivers from being enabled by default when
     'COMPILE_TEST' is set

  Device Property API:
   - Split 'device_get_child_node_count()' into a new helper
     'fwnode_get_child_node_count()' that doesn't require a device
     struct, making the API more symmetrical

  Driver Modernization (using 'fwnode_get_child_node_count()'):
   - Update 'leds-pwm-multicolor', 'leds-ncp5623' and 'leds-ncp5623' to
     use the new 'fwnode_get_child_node_count()' helper, removing their
     custom implementation
   - As above in the USB Type-C TCPM driver

  Driver Modernization (using new GPIO setter callbacks):
   - Convert 'leds-lgm-sso' to use new GPIO line value setter callbacks
     which return an integer for error handling
   - Convert 'leds-pca955x', 'leds-pca9532' and 'leds-tca6507' to use
     new GPIO setter callbacks

  Documentation:
   - Remove the '.rst' extension for 'leds-st1202' in the documentation
     index for consistency

  LP8860 LEDs:
   - Use 'regmap_multi_reg_write()' for EEPROM writes instead of manual
     looping
   - Use scoped mutex guards and 'devm_mutex_init()' to simplify
     function exits and ensure automatic cleanup
   - Remove default register definitions that are unused when regmap
     caching is not active
   - Use 'devm_regulator_get_enable_optional()' to handle the optional
     regulator, simplifying enabling and removing manual disabling
   - Refactor 'lp8860_unlock_eeprom()' to only perform the unlock
     operation, removing the lock part and an unnecessary parameter
   - Use a 'devm' action to disable the enable-GPIO, simplifying cleanup
     and error paths, and remove the now-empty '.remove()' function

  Turris Omnia LEDs:
   - Drop unnecessary commas in terminator entries of 'struct attribute'
     and 'struct of_device_id' arrays

  MT6370 RGB LEDs:
   - Use the 'LINEAR_RANGE()' for defining 'struct linear_range' entries
     to improve robustness

  Texas Instruments TPS6131x:
   - Add new devicetree bindings for the TI TPS61310/TPS61311 flash LED

Pull MM updates from Andrew Morton:

 - "Add folio_mk_pte()" from Matthew Wilcox simplifies the act of
   creating a pte which addresses the first page in a folio and reduces
   the amount of plumbing which architecture must implement to provide
   this.

 - "Misc folio patches for 6.16" from Matthew Wilcox is a shower of
   largely unrelated folio infrastructure changes which clean things up
   and better prepare us for future work.

 - "memory,x86,acpi: hotplug memory alignment advisement" from Gregory
   Price adds early-init code to prevent x86 from leaving physical
   memory unused when physical address regions are not aligned to memory
   block size.

 - "mm/compaction: allow more aggressive proactive compaction" from
   Michal Clapinski provides some tuning of the (sadly, hard-coded (more
   sadly, not auto-tuned)) thresholds for our invokation of proactive
   compaction. In a simple test case, the reduction of a guest VM's
   memory consumption was dramatic.

 - "Minor cleanups and improvements to swap freeing code" from Kemeng
   Shi provides some code cleaups and a small efficiency improvement to
   this part of our swap handling code.

 - "ptrace: introduce PTRACE_SET_SYSCALL_INFO API" from Dmitry Levin
   adds the ability for a ptracer to modify syscalls arguments. At this
   time we can alter only "system call information that are used by
   strace system call tampering, namely, syscall number, syscall
   arguments, and syscall return value.

   This series should have been incorporated into mm.git's "non-MM"
   branch, but I goofed.

 - "fs/proc: extend the PAGEMAP_SCAN ioctl to report guard regions" from
   Andrei Vagin extends the info returned by the PAGEMAP_SCAN ioctl
   against /proc/pid/pagemap. This permits CRIU to more efficiently get
   at the info about guard regions.

 - "Fix parameter passed to page_mapcount_is_type()" from Gavin Shan
   implements that fix. No runtime effect is expected because
   validate_page_before_insert() happens to fix up this error.

 - "kernel/events/uprobes: uprobe_write_opcode() rewrite" from David
   Hildenbrand basically brings uprobe text poking into the current
   decade. Remove a bunch of hand-rolled implementation in favor of
   using more current facilities.

 - "mm/ptdump: Drop assumption that pxd_val() is u64" from Anshuman
   Khandual provides enhancements and generalizations to the pte dumping
   code. This might be needed when 128-bit Page Table Descriptors are
   enabled for ARM.

 - "Always call constructor for kernel page tables" from Kevin Brodsky
   ensures that the ctor/dtor is always called for kernel pgtables, as
   it already is for user pgtables.

   This permits the addition of more functionality such as "insert hooks
   to protect page tables". This change does result in various
   architectures performing unnecesary work, but this is fixed up where
   it is anticipated to occur.

 - "Rust support for mm_struct, vm_area_struct, and mmap" from Alice
   Ryhl adds plumbing to permit Rust access to core MM structures.

 - "fix incorrectly disallowed anonymous VMA merges" from Lorenzo
   Stoakes takes advantage of some VMA merging opportunities which we've
   been missing for 15 years.

 - "mm/madvise: batch tlb flushes for MADV_DONTNEED and MADV_FREE" from
   SeongJae Park optimizes process_madvise()'s TLB flushing.

   Instead of flushing each address range in the provided iovec, we
   batch the flushing across all the iovec entries. The syscall's cost
   was approximately halved with a microbenchmark which was designed to
   load this particular operation.

 - "Track node vacancy to reduce worst case allocation counts" from
   Sidhartha Kumar makes the maple tree smarter about its node
   preallocation.

   stress-ng mmap performance increased by single-digit percentages and
   the amount of unnecessarily preallocated memory was dramaticelly
   reduced.

 - "mm/gup: Minor fix, cleanup and improvements" from Baoquan He removes
   a few unnecessary things which Baoquan noted when reading the code.

 - ""Enhance sysfs handling for memory hotplug in weighted interleave"
   from Rakie Kim "enhances the weighted interleave policy in the memory
   management subsystem by improving sysfs handling, fixing memory
   leaks, and introducing dynamic sysfs updates for memory hotplug
   support". Fixes things on error paths which we are unlikely to hit.

 - "mm/damon: auto-tune DAMOS for NUMA setups including tiered memory"
   from SeongJae Park introduces new DAMOS quota goal metrics which
   eliminate the manual tuning which is required when utilizing DAMON
   for memory tiering.

 - "mm/vmalloc.c: code cleanup and improvements" from Baoquan He
   provides cleanups and small efficiency improvements which Baoquan
   found via code inspection.

 - "vmscan: enforce mems_effective during demotion" from Gregory Price
   changes reclaim to respect cpuset.mems_effective during demotion when
   possible. because presently, reclaim explicitly ignores
   cpuset.mems_effective when demoting, which may cause the cpuset
   settings to violated.

   This is useful for isolating workloads on a multi-tenant system from
   certain classes of memory more consistently.

 - "Clean up split_huge_pmd_locked() and remove unnecessary folio
   pointers" from Gavin Guo provides minor cleanups and efficiency gains
   in in the huge page splitting and migrating code.

 - "Use kmem_cache for memcg alloc" from Huan Yang creates a slab cache
   for `struct mem_cgroup', yielding improved memory utilization.

 - "add max arg to swappiness in memory.reclaim and lru_gen" from
   Zhongkun He adds a new "max" argument to the "swappiness=" argument
   for memory.reclaim MGLRU's lru_gen.

   This directs proactive reclaim to reclaim from only anon folios
   rather than file-backed folios.

 - "kexec: introduce Kexec HandOver (KHO)" from Mike Rapoport is the
   first step on the path to permitting the kernel to maintain existing
   VMs while replacing the host kernel via file-based kexec. At this
   time only memblock's reserve_mem is preserved.

 - "mm: Introduce for_each_valid_pfn()" from David Woodhouse provides
   and uses a smarter way of looping over a pfn range. By skipping
   ranges of invalid pfns.

 - "sched/numa: Skip VMA scanning on memory pinned to one NUMA node via
   cpuset.mems" from Libo Chen removes a lot of pointless VMA scanning
   when a task is pinned a single NUMA mode.

   Dramatic performance benefits were seen in some real world cases.

 - "JFS: Implement migrate_folio for jfs_metapage_aops" from Shivank
   Garg addresses a warning which occurs during memory compaction when
   using JFS.

 - "move all VMA allocation, freeing and duplication logic to mm" from
   Lorenzo Stoakes moves some VMA code from kernel/fork.c into the more
   appropriate mm/vma.c.

 - "mm, swap: clean up swap cache mapping helper" from Kairui Song
   provides code consolidation and cleanups related to the folio_index()
   function.

 - "mm/gup: Cleanup memfd_pin_folios()" from Vishal Moola does that.

 - "memcg: Fix test_memcg_min/low test failures" from Waiman Long
   addresses some bogus failures which are being reported by the
   test_memcontrol selftest.

 - "eliminate mmap() retry merge, add .mmap_prepare hook" from Lorenzo
   Stoakes commences the deprecation of file_operations.mmap() in favor
   of the new file_operations.mmap_prepare().

   The latter is more restrictive and prevents drivers from messing with
   things in ways which, amongst other problems, may defeat VMA merging.

 - "memcg: decouple memcg and objcg stocks"" from Shakeel Butt decouples
   the per-cpu memcg charge cache from the objcg's one.

   This is a step along the way to making memcg and objcg charging
   NMI-safe, which is a BPF requirement.

 - "mm/damon: minor fixups and improvements for code, tests, and
   documents" from SeongJae Park is yet another batch of miscellaneous
   DAMON changes. Fix and improve minor problems in code, tests and
   documents.

 - "memcg: make memcg stats irq safe" from Shakeel Butt converts memcg
   stats to be irq safe. Another step along the way to making memcg
   charging and stats updates NMI-safe, a BPF requirement.

 - "Let unmap_hugepage_range() and several related functions take folio
   instead of page" from Fan Ni provides folio conversions in the
   hugetlb code.

 "In this round, Matthew converted most of page operations to using
  folio. Beyond the work, we've applied some performance tunings such as
  GC and linear lookup, in addition to enhancing fault injection and
  sanity checks.

  Enhancements:
   - large number of folio conversions
   - add a control to turn on/off the linear lookup for performance
   - tune GC logics for zoned block device
   - improve fault injection and sanity checks

  Bug fixes:
   - handle error cases of memory donation
   - fix to correct check conditions in f2fs_cross_rename
   - fix to skip f2fs_balance_fs() if checkpoint is disabled
   - don't over-report free space or inodes in statvfs

Pull arm64 updates from Will Deacon:
 "The headline feature is the re-enablement of support for Arm's
  Scalable Matrix Extension (SME) thanks to a bumper crop of fixes
  from Mark Rutland.

  If matrices aren't your thing, then Ryan's page-table optimisation
  work is much more interesting.

  Summary:

  ACPI, EFI and PSCI:

   - Decouple Arm's "Software Delegated Exception Interface" (SDEI)
     support from the ACPI GHES code so that it can be used by platforms
     booted with device-tree

   - Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
     runtime calls

   - Fix a node refcount imbalance in the PSCI device-tree code

  CPU Features:

   - Ensure register sanitisation is applied to fields in ID_AA64MMFR4

   - Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM
     guests can reliably query the underlying CPU types from the VMM

   - Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
     to our context-switching, signal handling and ptrace code

  Entry code:

   - Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be
     selected

  Memory management:

   - Prevent BSS exports from being used by the early PI code

   - Propagate level and stride information to the low-level TLB
     invalidation routines when operating on hugetlb entries

   - Use the page-table contiguous hint for vmap() mappings with
     VM_ALLOW_HUGE_VMAP where possible

   - Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode"
     and hook this up on arm64 so that the trailing DSB (used to publish
     the updates to the hardware walker) can be deferred until the end
     of the mapping operation

   - Extend mmap() randomisation for 52-bit virtual addresses (on par
     with 48-bit addressing) and remove limited support for
     randomisation of the linear map

  Perf and PMUs:

   - Add support for probing the CMN-S3 driver using ACPI

   - Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers

  Selftests:

   - Fix FPSIMD and SME tests to align with the freshly re-enabled SME
     support

   - Fix default setting of the OUTPUT variable so that tests are
     installed in the right location

  vDSO:

   - Replace raw counter access from inline assembly code with a call to
     the the __arch_counter_get_cntvct() helper function

  Miscellaneous:

   - Add some missing header inclusions to the CCA headers

   - Rework rendering of /proc/cpuinfo to follow the x86-approach and
     avoid repeated buffer expansion (the user-visible format remains
     identical)

   - Remove redundant selection of CONFIG_CRC32

   - Extend early error message when failing to map the device-tree
     blob"

 "Once again, the changes are dominated by cpufreq updates, but this

  Still, there is also a significant update of the intel_pstate driver
  making it register an energy model when running on a hybrid platform
  which is used for enabling energy-aware scheduling (EAS) if the driver
  operates in the passive mode (and schedutil is used as the cpufreq
  governor for all CPUs which is the passive mode default).

  There are some amd-pstate driver updates too, for a good measure,
  including the "Requested CPU Min frequency" BIOS option support and
  new online/offline callbacks.

  In the cpuidle space, the most significant change is the addition of a
  C1 demotion on/off sysfs knob to intel_idle which should help some
  users to configure their systems more precisely. There is also the
  conversion of the PSCI cpuidle driver to a faux device one and there
  are two small updates of cpuidle governors.

  Device power management is also modified quite a bit, especially the
  handling of devices with asynchronous suspend and resume enabled
  during system transitions. They are now going to be handled more
  asynchronously during suspend transitions and somewhat less
  aggressively during resume transitions.

  Apart from the above, the operating performance points (OPP) library
  is now going to use mutex locking guards and scope-based cleanup
  helpers and there is the usual bunch of assorted fixes and code
  cleanups.

  Specifics:

   - Fix potential division-by-zero error in em_compute_costs() (Yaxiong
     Tian)

   - Fix typos in energy model documentation and example driver code
     (Moon Hee Lee, Atul Kumar Pant)

 "Boot code changes:

   - A large series of changes to reorganize the x86 boot code into a
     better isolated and easier to maintain base of PIC early startup
     code in arch/x86/boot/startup/, by Ard Biesheuvel.

     Motivation & background:

  	| Since commit
  	|
  	|    c88d71508e ("x86/boot/64: Rewrite startup_64() in C")
  	|
  	| dated Jun 6 2017, we have been using C code on the boot path in a way
  	| that is not supported by the toolchain, i.e., to execute non-PIC C
  	| code from a mapping of memory that is different from the one provided
  	| to the linker. It should have been obvious at the time that this was a
  	| bad idea, given the need to sprinkle fixup_pointer() calls left and
  	| right to manipulate global variables (including non-pointer variables)
  	| without crashing.
  	|
  	| This C startup code has been expanding, and in particular, the SEV-SNP
  	| startup code has been expanding over the past couple of years, and
  	| grown many of these warts, where the C code needs to use special
  	| annotations or helpers to access global objects.

Pull erofs updates from Gao Xiang:
 "In this cycle, Intel QAT hardware accelerators are supported to
  improve DEFLATE decompression performance. I've tested it with the
  enwik9 dataset of 1 MiB pclusters on our Intel Sapphire Rapids
  bare-metal server and a PL0 ESSD, and the sequential read performance
  even surpasses LZ4 software decompression on this setup.

  In addition, a `fsoffset` mount option is introduced for file-backed
  mounts to specify the filesystem offset in order to adapt customized
  container formats.

  And other improvements and minor cleanups. Summary:

   - Add a `fsoffset` mount option to specify the filesystem offset

   - Support Intel QAT accelerators to boost up the DEFLATE algorithm

   - Initialize per-CPU workers and CPU hotplug hooks lazily to avoid
     unnecessary overhead when EROFS is not mounted

   - Fix file handle encoding for 64-bit NIDs

   - Minor cleanups"

b4a29efc51 erofs: support DEFLATE decompression by using Intel QAT
This patch introduces the use of the Intel QAT to offload EROFS data
decompression, aiming to improve the decompression performance.

A 285MiB dataset is used with the following command to create EROFS
images with different cluster sizes:
     $ mkfs.erofs -zdeflate,level=9 -C{4096,16384,65536,131072,262144}

Fio is used to test the following read patterns:
     $ fio -filename=testfile -bs=4k -rw=read -name=job1
     $ fio -filename=testfile -bs=4k -rw=randread -name=job1
     $ fio -filename=testfile -bs=4k -rw=randread --io_size=14m -name=job1

b4fe7398de PCI/AER: Add sysfs attributes for log ratelimits
Allow userspace to read/write log ratelimits per device (including
enable/disable). Create aer/ sysfs directory to store them and any
future AER configs.

The new sysfs files are:

  /sys/bus/pci/devices/*/aer/correctable_ratelimit_burst
  /sys/bus/pci/devices/*/aer/correctable_ratelimit_interval_ms
  /sys/bus/pci/devices/*/aer/nonfatal_ratelimit_burst
  /sys/bus/pci/devices/*/aer/nonfatal_ratelimit_interval_ms

The default values are ratelimit_burst=10, ratelimit_interval_ms=5000, so
if we try to emit more than 10 messages in a 5 second period, some are
suppressed.

Update AER sysfs ABI filename to reflect the broader scope of AER sysfs
attributes (e.g. stats and ratelimits).

  Documentation/ABI/testing/sysfs-bus-pci-devices-aer_stats ->
    sysfs-bus-pci-devices-aer

Tested using aer-inject[1]. Configured correctable log ratelimit to 5.
Sent 6 AER errors. Observed 5 errors logged while AER stats
(cat /sys/bus/pci/devices/<dev>/aer_dev_correctable) shows 6.

Disabled ratelimiting and sent 6 more AER errors. Observed all 6 errors
logged and accounted in AER stats (12 total errors).

[1] https://git.kernel.org/pub/scm/linux/kernel/git/gong.chen/aer-inject.git

[bhelgaas: note fatal errors are not ratelimited, "aer_report" ->
"aer_info", replace ratelimit_log_enable toggle with *_ratelimit_interval_ms]

Jonathan writes:

IIO: New device support, features and cleanup for 6.16 - take 2

Note - last minute rebase was to drop a typo patch that I'd accidentally
picked up (in the microblaze arch Kconfig)
Take 2 is due to that rebase messing up some fixes tags that were
referring to patches after that point.

There is a known merge conflict due to changes in neighbouring lines.

Stephen's resolution in linux-next is:
https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/

Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those
who have been doing much of this work for some time. Lars-Peter is
removed from the entry having moved on to other topics.  Thanks
Nuno, David and Andy for stepping up and Lars-Peter for all your
hard work in the past!

Includes the usual mix of new device support, features and general
cleanup.

This time we also have some tree wide changes.

- Rip out the iio_device_claim_direct_scoped() as it proved hard to work
  with.  This series includes quite a few related cleanups such as use
  of guard or factoring code out to allow direct returns.
- Switch from iio_device_claim/release_direct_mode() to new
  iio_device_claim/release_direct() which is structured so that sparse
  can warn on failed releases. There were a few false positives but
  those were mostly in code that benefited from being cleaned up as part
  of this process.
- Introduce iio_push_to_buffers_with_ts() to replace the _timestamp()
  version over time. This version takes the size of the supplied buffer
  which the core checks is at least as big as expected by calculation
  from channel descriptions of those channels enabled. Use this in
  an initial set of drivers.
- Add macros for IIO_DECLARE_BUFFER_WITH_TS() and
  IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure
  correctly aligned buffers for timestamps being added onto the end of
  channel data.

New device support
------------------

adi,ad3530r
- New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with
  programmable gain controls. R variants have internal references.
adi,ad7476
- Add support (dt compatible only) for the Rohm BU79100G ADC which is
  fully compatible with the ti,ads7866.
adi,ad7606
- Support ad7606c-16 and ad7606c-18 devices. Includes switch to dynamic
  channel information allocation.
adi,ad7380
- Add support for the AD7389-4
dfrobot,sen0322
- New driver for this oxygen sensor.
mediatek,mt2701-auxadc
- Add binding for MT6893 which is fully compatible with already supported
  MT8173.
meson-saradc
- Support the GXLX SoCs.  Mostly this is a workaround for some unrelated
  clock control bits found in the ADC register map.
nuvoton,nct7201
- New driver for NCT7201 and NCT7202 I2C ADCs.
rohm,bd79124
- New driver for this 12-bit, 8-channel SAR ADC.
- Switch to new set_rv etc gpio callbacks that were added in 6.15.
rohm,bd79703
- Add support for BD79700, BD79701 and BD79702 DACs that have subsets of
  functionality of the already supported bd79703.  Included making this
  driver suitable for support device variants.
st,stm32-lptimer
- Add support for stm32pm25 to this trigger.

Features
--------

Beyond IIO
- Property iterator for named children.
core
- Enable writes for 64 bit integers used for standard IIO ABI elements.
  Previously these could be read only.
- Helper library that should avoid code duplication for simpler ADC
  bindings that have a child node per channel.
- Enforce that IIO_DMA_MINALIGN is always at least 8 (almost always true
  and simplifies code on all significant architectures)
core/backend
- Add support to control source of data - useful when the HDL includes
  things like generated ramps for testing purposes. Enable this for
  adi-axi-dac
adi,ad3552-hs
- Add debugfs related callbacks to allow debug access to register contents.
adi,ad4000
- Support SPI offload with appropriate FPGA firmware along with improving
  documentation.
adi,ad7293
- Add support for external reference voltage.
adi,ad7606
- Support SPI offload.

hid-sensor-prox
- Support 16-bit report sizes as seen on some Intel platforms.
invensense,icm42600
- Enable use of named interrupts to avoid problems with some wiring choices.
  Get the interrupt by name, but fallback to previous assumption on the first
  being INT1 if no names are supplied.
microchip,mcp3911
- Add reset gpio support.
rohm,bh7150
- Add reset gpio support.
st,stm32
- Add support to control oversampling.
ti,adc128s052
- Add support for ROHM BD79104 which is early compatible with the TI
  parts already supported by this driver. Includes some general driver
  cleanup and a separate dt binding.
- Simplify reference voltage handling by assuming it is fixed after enabling
  the supply.
winsen,mhz19b
- New driver for this C02 sensor.

Cleanup and minor fixes
-----------------------

dt-bindings
- Correct indentation and style for DTS examples.
- Use unevalutateProperties for SPI devices instead of additionalProperties
  to allow generic SPI properties from spi-peripheral-props.yaml
ABI Docs
- Add missing docs for sampling_frequency when it applies only to events.
Treewide
- Various minor tweaks, comment fixes and similar.
- Sort TI ADCs in Kconfig that had gotten out of order.
- Switch various drives that provide GPIO chip functionality to the new
  callbacks with return values.
- Standardize on { } formatting for all array sentinels.
- Make use of aligned_s64 in a few places to replace either wrong types
  or manually defined equivalents.
- Drop places where spi bits_per_word is set to 8 because that is the
  default anyway.

adi,ad_sigma_delta library
- Avoid a potential use of uninitialized data if reg_size has a value
  that is not supported (no drivers hit this but it is reasonable hardening)
adi,ad4030
- Add error checking for scan types and no longer store it in state.
- Rework code to reduce duplication.
- Move setting the mode from buffer preenable() to update_scan_mode(),
  better matching expected semantics of the two different callbacks.
- Improve data marshalling comments.
adi,ad4695
- Use u16 for buffer elements as oversampling is not yet supported except
  with SPI offload (which doesn't use this path).
adi,ad5592r
- Clean up destruction of mutexes.
- Use lock guards to simplify code (later patch fixes a missed unlock)
adi,ad5933
- Correct some incorrect settling times.
adi,ad7091
- Deduplicate handling of writable vs volatile registers as they are the
  inverse of each other for this device.
adi,ad7124
- Fix 3db Filter frequency.
- Remove ability to directly write the filter frequency (which was broken)
- Register naming improvements.
adi,ad7606
- Add a missing return value check.

adi,admv1013
- Cleanup a pointless ternary.
adi,admv8818
- Fix up LPF Band 5 frequency which was slightly wrong.
- Fix an integer overflow.
- Fix range calculation
adi,adt7316
- Replace irqd_get_trigger_type(irq_get_irq_data()) with simpler
  irq_get_trigger_type()
adi,adxl345
- Use regmap cache instead of various state variables that were there to
  reduce bus accesses.
- Make regmap return value checking consistent across all call sites.
adi,axi-dac
- Add a check on number of channels (0 to 15 valid)
allwinner,sun20i
- Use new adc-helpers to replace local parsing code for channel nodes.
bosch,bmp290
- Move to local variables for sensor data marshalling removing the need
  for a messy definition that has to work for all supported parts.
  Follow up fix adds a missing initialization.
dynaimage,al3010 and dynaimage,al3320a
- Various minor cleanup to bring these drivers inline with reviewed feedback
  given on a new driver.
- Fix an error path in which power down is not called when it should be.
- Switch to regmap.

- Flush fifo when changing the timeout to avoid potential long wait
  for samples.
hid-sensor-rotation
- Remove an __aligned(16) marking that doesn't seem to be justified.
kionix,kxcjk-1013
- Deduplicate code for setting up interrupts.
microchip,mcp3911
- Fix handling of conversion results register which differs across supported
  devices.
idt,zopt2201
- Avoid duplicating register lists as all volatile registers are the
  inverse of writeable registers on this device.
renesas,rzg2l
- Use new adc-helpers to replace local parsing code for channel nodes.
ti,ads1298
- Fix a missing Kconfig dependency.

aaf05e96e9 kernel/watchdog: add /sys/kernel/{hard,soft}lockup_count
Patch series "sysfs: add counters for lockups and stalls", v2.

Commits 9db89b4111 ("exit: Expose "oops_count" to sysfs") and
8b05aa2633 ("panic: Expose "warn_count" to sysfs") added counters for
oopses and warnings to sysfs, and these two patches do the same for
hard/soft lockups and RCU stalls.

All of these counters are useful for monitoring tools to detect whether
the machine is healthy.  If the kernel has experienced a lockup or a
stall, it's probably due to a kernel bug, and I'd like to detect that
quickly and easily.  There is currently no way to detect that, other than
parsing dmesg.  Or observing indirect effects: such as certain tasks not
responding, but then I need to observe all tasks, and it may take a while
until these effects become visible/measurable.  I'd rather be able to
detect the primary cause more quickly, possibly before everything falls
apart.


This patch (of 2):

There is /proc/sys/kernel/hung_task_detect_count, /sys/kernel/warn_count
and /sys/kernel/oops_count but there is no userspace-accessible counter
for hard/soft lockups.  Having this is useful for monitoring tools.

e341f9c3c8 mm/mempolicy: Weighted Interleave Auto-tuning
On machines with multiple memory nodes, interleaving page allocations
across nodes allows for better utilization of each node's bandwidth. 
Previous work by Gregory Price [1] introduced weighted interleave, which
allowed for pages to be allocated across nodes according to user-set
ratios.

Ideally, these weights should be proportional to their bandwidth, so that
under bandwidth pressure, each node uses its maximal efficient bandwidth
and prevents latency from increasing exponentially.

Previously, weighted interleave's default weights were just 1s -- which
would be equivalent to the (unweighted) interleave mempolicy, which goes
through the nodes in a round-robin fashion, ignoring bandwidth
information.

This patch has two main goals: First, it makes weighted interleave easier
to use for users who wish to relieve bandwidth pressure when using nodes
with varying bandwidth (CXL).  By providing a set of "real" default
weights that just work out of the box, users who might not have the
capability (or wish to) perform experimentation to find the most optimal
weights for their system can still take advantage of bandwidth-informed
weighted interleave.

Second, it allows for weighted interleave to dynamically adjust to
hotplugged memory with new bandwidth information.  Instead of manually
updating node weights every time new bandwidth information is reported or
taken off, weighted interleave adjusts and provides a new set of default
weights for weighted interleave to use when there is a change in bandwidth
information.

To meet these goals, this patch introduces an auto-configuration mode for
the interleave weights that provides a reasonable set of default weights,
calculated using bandwidth data reported by the system.  In auto mode,
weights are dynamically adjusted based on whatever the current bandwidth
information reports (and responds to hotplug events).

This patch still supports users manually writing weights into the nodeN
sysfs interface by entering into manual mode.  When a user enters manual
mode, the system stops dynamically updating any of the node weights, even
during hotplug events that shift the optimal weight distribution.

A new sysfs interface "auto" is introduced, which allows users to switch
between the auto (writing 1 or Y) and manual (writing 0 or N) modes.  The
system also automatically enters manual mode when a nodeN interface is
manually written to.

There is one functional change that this patch makes to the existing
weighted_interleave ABI: previously, writing 0 directly to a nodeN
interface was said to reset the weight to the system default.  Before this
patch, the default for all weights were 1, which meant that writing 0 and
1 were functionally equivalent.  With this patch, writing 0 is invalid.
