       - Remove sentinel elements from ctl_table structs in kernel/*
      
         Removing sentinels in ctl_table arrays reduces the build time size
         and runtime memory consumed by ~64 bytes per array. Removals for
         net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline
         through their respective subsystems making the next release the most
         likely place where the final series that removes the check for
         proc_name == NULL will land.
      
         This adds to removals already in arch/, drivers/ and fs/.
      
       - Adjust ctl_table definitions and references to allow constification
           - Remove unused ctl_table function arguments
           - Move non-const elements from ctl_table to ctl_table_header
           - Make ctl_table pointers const in ctl_table_root structure
      
         Making the static ctl_table structs const will increase safety by
         keeping the pointers to proc_handler functions in .rodata. Though no
         ctl_tables where made const in this PR, the ground work for making
         that possible has started with these changes sent by Thomas
         Weißschuh.

         - Simon Glass wanted to support binman's output properties in order
           to check their validity using the binding checks and proposed
           changes with the missing properties as well as a binman compatible.
      
         - Krzysztof Kozlowski on his side shared a new yaml for describing
           Samsung's OneNAND interface.
      
         - The interface with NVMEM has also been slightly improved/fixed,
           especially now that OTP are also supported in the NAND subsystem.
      
         - Along with these changes, small cleanups have also been contributed
           around ID tables, structure sizes, arithmetic checks and comments.
      
        Raw NAND subsystem:
      
         - Two small fixes, one in the Hynix vendor code for properly
           returning an error which might have been ignored and another in the
           Davinci driver to properly synchronize the controller with the gpio
           domain.
      
        SPI NOR subsystem:
      
         - SPI NOR now uses div_u64() instead of div64_u64() in places where
           the divisor is 32 bits. Many 32 bit architectures can optimize this
           variant better than a full 64 bit divide"

      Problem statement: During the system boot time, an application request
      for the bulk volume of cleared range bias memory when the clear_avail
      is zero, we dont fallback into normal allocation method as we had an
      unnecessary clear_avail check which prevents the fallback method leads

      Solution: Remove the unnecessary clear_avail check in the range bias

       - The locking around cpuset hotplug processing has always been a bit of
         mess which was worked around by making hotplug processing

         We tried to make the behavior synchronous a while ago but that led to
         lockdep splats. Waiman took another stab at cleaning up and making it

      Pull KVM updates from Paolo Bonzini:
       "ARM:
      
         - Move a lot of state that was previously stored on a per vcpu basis
           into a per-CPU area, because it is only pertinent to the host while
           the vcpu is loaded. This results in better state tracking, and a
           smaller vcpu structure.
      
         - Add full handling of the ERET/ERETAA/ERETAB instructions in nested
           virtualisation. The last two instructions also require emulating
           part of the pointer authentication extension. As a result, the trap
           handling of pointer authentication has been greatly simplified.
      
         - Turn the global (and not very scalable) LPI translation cache into
           a per-ITS, scalable cache, making non directly injected LPIs much
           cheaper to make visible to the vcpu.
      
         - A batch of pKVM patches, mostly fixes and cleanups, as the
           upstreaming process seems to be resuming. Fingers crossed!
      
         - Allocate PPIs and SGIs outside of the vcpu structure, allowing for
           smaller EL2 mapping and some flexibility in implementing more or
           less than 32 private IRQs.
      
         - Purge stale mpidr_data if a vcpu is created after the MPIDR map has
           been created.
      
         - Preserve vcpu-specific ID registers across a vcpu reset.
      
         - Various minor cleanups and improvements.
      
        LoongArch:
      
         - Add ParaVirt IPI support
      
         - Add software breakpoint support
      
         - Add mmio trace events support
      
        RISC-V:
      
         - Support guest breakpoints using ebreak
      
         - Introduce per-VCPU mp_state_lock and reset_cntx_lock
      
         - Virtualize SBI PMU snapshot and counter overflow interrupts
      
         - New selftests for SBI PMU and Guest ebreak
      
         - Some preparatory work for both TDX and SNP page fault handling.
      
           This also cleans up the page fault path, so that the priorities of
           various kinds of fauls (private page, no memory, write to read-only
           slot, etc.) are easier to follow.
      
        x86:
      
         - Minimize amount of time that shadow PTEs remain in the special
           REMOVED_SPTE state.
      
           This is a state where the mmu_lock is held for reading but
           concurrent accesses to the PTE have to spin; shortening its use
           allows other vCPUs to repopulate the zapped region while the zapper
           finishes tearing down the old, defunct page tables.
      
         - Advertise the max mappable GPA in the "guest MAXPHYADDR" CPUID
           field, which is defined by hardware but left for software use.
      
           This lets KVM communicate its inability to map GPAs that set bits
           51:48 on hosts without 5-level nested page tables. Guest firmware
           is expected to use the information when mapping BARs; this avoids
           that they end up at a legal, but unmappable, GPA.
      
         - Fixed a bug where KVM would not reject accesses to MSR that aren't
           supposed to exist given the vCPU model and/or KVM configuration.
      
         - As usual, a bunch of code cleanups.
      
        x86 (AMD):
      
         - Implement a new and improved API to initialize SEV and SEV-ES VMs,
           which will also be extendable to SEV-SNP.
      
           The new API specifies the desired encryption in KVM_CREATE_VM and
           then separately initializes the VM. The new API also allows
           customizing the desired set of VMSA features; the features affect
           the measurement of the VM's initial state, and therefore enabling
           them cannot be done tout court by the hypervisor.
      
           While at it, the new API includes two bugfixes that couldn't be
           applied to the old one without a flag day in userspace or without
           affecting the initial measurement. When a SEV-ES VM is created with
           the new VM type, KVM_GET_REGS/KVM_SET_REGS and friends are rejected
           once the VMSA has been encrypted. Also, the FPU and AVX state will
           be synchronized and encrypted too.
      
         - Support for GHCB version 2 as applicable to SEV-ES guests.
      
           This, once more, is only accessible when using the new
           KVM_SEV_INIT2 flow for initialization of SEV-ES VMs.
      
        x86 (Intel):
      
         - An initial bunch of prerequisite patches for Intel TDX were merged.
      
           They generally don't do anything interesting. The only somewhat
           user visible change is a new debugging mode that checks that KVM's
           MMU never triggers a #VE virtualization exception in the guest.
      
         - Clear vmcs.EXIT_QUALIFICATION when synthesizing an EPT Misconfig
           VM-Exit to L1, as per the SDM.
      
        Generic:
      
         - Use vfree() instead of kvfree() for allocations that always use
           vcalloc() or __vcalloc().
      
         - Remove .change_pte() MMU notifier - the changes to non-KVM code are
           small and Andrew Morton asked that I also take those through the
           KVM tree.
      
           The callback was only ever implemented by KVM (which was also the
           original user of MMU notifiers) but it had been nonfunctional ever
           since calls to set_pte_at_notify were wrapped with
           invalidate_range_start and invalidate_range_end... in 2012.
      
        Selftests:
      
         - Enhance the demand paging test to allow for better reporting and
           stressing of UFFD performance.
      
         - Convert the steal time test to generate TAP-friendly output.
      
         - Fix a flaky false positive in the xen_shinfo_test due to comparing
           elapsed time across two different clock domains.
      
         - Skip the MONITOR/MWAIT test if the host doesn't actually support
           MWAIT.
      
         - Avoid unnecessary use of "sudo" in the NX hugepage test wrapper
           shell script, to play nice with running in a minimal userspace
           environment.
      
         - Allow skipping the RSEQ test's sanity check that the vCPU was able
           to complete a reasonable number of KVM_RUNs, as the assert can fail
           on a completely valid setup.
      
           If the test is run on a large-ish system that is otherwise idle,
           and the test isn't affined to a low-ish number of CPUs, the vCPU
           task can be repeatedly migrated to CPUs that are in deep sleep
           states, which results in the vCPU having very little net runtime
           before the next migration due to high wakeup latencies.
      
         - Define _GNU_SOURCE for all selftests to fix a warning that was
           introduced by a change to kselftest_harness.h late in the 6.9
           cycle, and because forcing every test to #define _GNU_SOURCE is
           painful.
      
         - Provide a global pseudo-RNG instance for all tests, so that library
           code can generate random, but determinstic numbers.
      
         - Use the global pRNG to randomly force emulation of select writes
           from guest code on x86, e.g. to help validate KVM's emulation of
           locked accesses.
      
         - Allocate and initialize x86's GDT, IDT, TSS, segments, and default
           exception handlers at VM creation, instead of forcing tests to
           manually trigger the related setup.

      Pull CXL updates from Dave Jiang:
      
       - Three CXL mailbox passthrough commands are added to support the
         populating and clearing of vendor debug logs:
           - Get Log Capabilities
           - Get Supported Log Sub-List Commands
           - Clear Log
      
       - Add support of Device Phyiscal Address (DPA) to Host Physical Address
         (HPA) translation for CXL events of cxl_dram and cxl_general media.
      
         This allows user space to figure out which CXL region the event
         occured via trace event.
      
       - Connect CXL to CPER reporting.
      
         If a device is configured for firmware first, CXL event records are
         not sent directly to the host. Those records are reported through EFI
         Common Platform Error Records (CPER). Add support to route the CPER
         records through the CXL sub-system in order to provide DPA to HPA
         translation and also event decoding and tracing. This is useful for
         users to determine which system issues may correspond to specific
         hardware events.
      
       - A number of misc cleanups and fixes:
           - Fix for compile warning of cxl_security_ops
           - Add debug message for invalid interleave granularity
           - Enhancement to cxl-test event testing
           - Add dev_warn() on unsupported mixed mode decoder

       "This is the main pull request for the drm subsystems for 6.10.
      
        In drivers the main thing is a new driver for ARM Mali firmware based
        GPUs, otherwise there are a lot of changes to amdgpu/xe/i915/msm and
        scattered changes to everything else.
      
        In the core a bunch of headers and Kconfig was refactored, along with
        the addition of a new panic handler which is meant to provide a user
        friendly message when a panic happens and graphical display is
        enabled.
      
        New drivers:
         - panthor: ARM Mali/Immortalis CSF-based GPU driver

      platform/x86: Add new MeeGoPad ANX7428 Type-C Cross Switch driver · 2513563e
      Hans de Goede authored
      Some MeeGoPad top-set boxes have an ANX7428 Type-C Switch for USB3.1 Gen 1
      and DisplayPort over Type-C alternate mode support.
      
      The ANX7428 has a microcontroller which takes care of the PD negotiation
      and automatically sets the builtin Crosspoint Switch to send the right
      signal to the 4 highspeed pairs of the Type-C connector. It also takes
      care of HPD and AUX channel routing for DP alternate mode.
      
      IOW the ANX7428 operates fully autonomous and to the x5-Z8350 SoC
      things look like there simple is a USB-3 Type-A connector and a
      separate DisplayPort connector. Except that the BIOS does not
      power on the ANX7428 at boot (meh).
      
      Add a driver to power on the ANX7428. This driver is added under
      drivers/platform/x86 rather than under drivers/usb/typec for 2 reasons:
      
      1. This driver is specifically written to work with how the ANX7428 is
      described in the ACPI tables of the MeeGoPad x86 (Cherry Trail) devices.
      
      2. This driver only powers on the ANX7428 and does not do anything wrt
      its Type-C functionality. It should be possible to tell the controller
      which data- and/or power-role to negotiate and to swap the role(s) after
      negotiation but the MeeGoPad top-set boxes always draw their power from
      a separate power-connector and they only support USB host-mode. So this
      functionality is unnecessary and due to lack of documentation this is
      tricky to support.
