 Patchsets in this merge:
 
 - The 2 patch series "selftests/mm: clean up build output and verbosity"
   from Li Wang removes some noise from the MM selftests build out.
 
 - The 3 patch series "mm: Free contiguous order-0 pages efficiently"
   from Ryan Roberts speeds up the freeing of a batch of 0-order pages by
   first scanning them for coalescing opportunities.  This is applicable to
   vfree() and to the releasing of frozen pages.
 
 - The 11 patch series "mm/damon: introduce DAMOS failed region quota
   charge ratio" from SeongJae Park addresses a DAMOS usability issue: The
   DAMOS quota often exhausts prematurely because it charges for all memory
   attempted, causing slow and inconsistent performance when actions fail
   on unreclaimable memory.
 
   To fix this, a new feature lets users set a smaller, flexible quota
   charge ratio (via a numerator and denominator) for failed regions.
   Since failed actions cause less overhead, reducing their quota cost
   ensures more predictable and efficient DAMOS processing
 
 - The 8 patch series "selftests/cgroup: improve zswap tests robustness
   and support large page sizes" from Li Wang fixes various spurious
   failures and improves the overall robustness of the cgroup zswap
   selftests.
 
 - The 3 patch series "fix MAP_DROPPABLE not supported errno" from
   Anthony Yznaga fixes an issue in the mlock selftests on arm32.
 
 - The 2 patch series "mm: huge_memory: clean up defrag sysfs with
   shared" from Breno Leitao does some maintenance work in the huge_memory
   code.
 
 - The 3 patch series "treewide: fixup gfp_t printks" from Brendan
   Jackman uses the special vprintf() gfp_t conversion in various places.
 
 - The 6 patch series "mm: Fix vmemmap optimization accounting and
   initialization" from Muchun Song fixes several bugs in the vmemmap
   optimization, mainly around incorrect page accounting and memmap
   initialization in the DAX and memory hotplug paths.  It also fixes
   pageblock migratetype initialization and struct page initialization for
   ZONE_DEVICE compound pages.
 
 - The 4 patch series "mm/damon: repost non-hotfix reviewed patches in
   damon/next tree" from is a sprinkle of unrelated minor bugfixes for
   DAMON.
 
 - The 3 patch series "mm: remove page_mapped()" from David Hildenbrand
   remove this function from the tree, replacing it with folio_mapped().
 
 - The 10 patch series "mm/damon: let DAMON be paused and resumed" from
   SeongJae Park permits DAMON to be paused and resumed without losing its
   current state.
 
 - The 3 patch series "kasan: hw_tags: Disable tagging for stack and
   page-tables" from Muhammad Usama Anjum simplifies and speeds up kasan by
   removing its ineffective tagging of stacks and page tables.
 
 - The 7 patch series "mm/damon/reclaim,lru_sort: monitor all system rams
   by default" from SeongJae Park simplifies deployment on diverse hardware
   like NUMA systems by updating DAMON_RECLAIM and DAMON_LRU_SORT to
   automatically monitor the physical address range covering all System RAM
   areas by default, replacing the overly restrictive behavior that only
   targeted the single largest memory block to save on negligible overhead.
 
 - The 2 patch series "mm/damon/sysfs: document filters/ directory as
   deprecated" from SeongJae Park updates some DAMON docs.
 
 - The 8 patch series "mm: use spinlock guards for zone lock" from Dmitry
   Ilvokhin switches zone->lock handling over to using the guard()
   mechanisms.
 
 - The 2 patch series "mm/filemap: tighten mmap_miss hit accounting" from
   fujunjie fixes a flaw where the mmap_miss counter over-credited page
   cache hits during fault-arounds and page-fault retries.  This results in
   significant reduction of redundant synchronous mmap readahead I/O,
   drastically cutting down execution time and gigabytes read for sparse
   random or strided memory access workloads.
 
 - The 2 patch series "selftests/cgroup: Fix false positive failures in
   test_percpu_basic" from Li Wang fixes a couple of false-positives in the
   cgroup kmem selftests.
 
 - The 2 patch series "mm/damon/reclaim: support monitoring intervals
   auto-tuning" from SeongJae Park adds a new parameter to DAMON permitting
   DAMON_RECLAIM to automatically tune DAMON's sampling and aggregation
   intervals.
 
 - The 2 patch series "mm/damon/stat: add kdamond_pid parameter" from
   SeongJae Park chnges DAMON_STAT to provide the pid of its kdamond.
 
 - The 2 patch series "mm/kmemleak: dedupe verbose scan output" from
   Breno Leitao removes large amounts of duplicated backtraces from the
   verbose-mode kmemleak output.
 
 - The 8 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)"
   from David Hildenbrand reduces our use of CONFIG_HAVE_BOOTMEM_INFO_NODE,
   with a view to removing it entirely in a later series.
 
 - The 2 patch series "mm/damon: validate min_region_size to be power of
   2" from Liew Rui Yan prevents users from passing a non-power-of-2 value
   of `addr_unit', as this later results in undesirable behavior.
 
 - The 2 patch series "mm: document read_pages and simplify usage" from
   Frederick Mayle does as claimed.
 
 - The 3 patch series "tools/mm/page-types: Fix misc bugs" from Ye Liu
   fixes three issues in tools/mm/page-types.c.
 
 - The 4 patch series "mm: misc cleanups from __GFP_UNMAPPED series" from
   Brendan Jackman implements several cleanups in the page allocator and
   related code.
 
 - The 12 patch series "mm, swap: swap table phase IV: unify allocation"
   from Kairui Song unifies the allocation and charging of anon and shmem
   swap in folios, provides better synchronization, consolidates the
   metadata management, hence dropping the static array and map, and
   improves performance.
 
 - The 28 patch series "mm/damon: introduce data attributes monitoring"
   from SeongJae Park extends DAMON for monitoring general data attributes
   other than accesses.
 
 - The 5 patch series "mm/vmalloc: free unused pages on vrealloc()
   shrink" from Shivam Kalra implements the TODO in vrealloc() to unmap and
   free unused pages when shrinking across a page boundary.
 
 - The 3 patch series "mm/damon: documentation and comment fixes" from
   niecheng does as advertised.
 
 - The 3 patch series "remove mmap_action success, error hooks" from
   Lorenzo Stoakes eliminates custom hooks from mmap_action by removing the
   problematic success_hook which allowed drivers to improperly access
   uninitialized VMAs.  It replaces the error_hook with a simple error-code
   field and updates the memory char driver accordingly.
 
 - The 14 patch series "mm/damon: minor improvements for code readability
   and tests" from SeongJae Park implements minor improvements in code
   readability and tests for DAMON.
 
 - The 2 patch series "mm/damon: fix macro arguments and clarify quota
   goals doc" from Maksym Shcherba does those things.
 
 - The 2 patch series "userfaultfd: merge fs/userfaultfd.c into
   mm/userfaultfd.c" from Mike Rapoport performs that code movement.
 
 - The 15 patch series "mm/mglru: improve reclaim loop and dirty folio"
   from Kairui Song and others cleans up and slightly improves MGLRU's
   reclaim loop and dirty writeback handling.  Large performance
   improvements are measured.
 
 - The 3 patch series "use vma locks for proc/pid/{smaps|numa_maps}
   reads" from Suren Baghdasaryan uses per-vma locks when reading
   /proc/pid/smaps and /proc/pid/numa_maps similar to reduce contention on
   central mmap_lock.
 
 - The 2 patch series "refactors thpsize_shmem_enabled_store() and
   thpsize_shmem_enabled_show()" from Ran Xiaokai provides some cleanup
   work in the THP code.
 
 - The 2 patch series "selftests/memfd: fix compilation warnings" from
   Konstantin Khorenko fixes a few build glitches in the memfd selftest
   code.
 
 - The 4 patch series "memcg: shrink obj_stock_pcp and cache multiple
   objcgs" from Shakeel Butt resolves a 68% performance regression caused
   by NUMA-node cache thrashing around struct obj_stock_pcp by shrinking
   its existing fields and expanding it into a multi-slot array that caches
   up to five obj_cgroup pointers per CPU, allowing per-node variants of
   the same memcg to coexist within a single 64-byte cache line.
 
 - The 2 patch series "zram: writeback fixes" from Sergey Senozhatsky
   addresses a couple of unrelated zram writeback issues.
 
 - The 9 patch series "mm: switch THP shrinker to list_lru" from Johannes
   Weiner resolves NUMA-awareness issues and streamlines callsite
   interaction by refactoring and extending the list_lru API to completely
   replace the complex, open-coded deferred split queue for Transparent
   Huge Pages (THPs).
 
 - The 2 patch series "mm: improve large folio readahead for exec memory"
   from Usama Arif improves large-folio readahead on systems like 64K-page
   arm64 by preventing the mmap_miss check from permanently disabling
   target-oriented VM_EXEC readahead, and by generalizing the
   force_thp_readahead gate to support mappings with any usefully large
   maximum folio order under the cache cap.
 
 - The 6 patch series "userfaultfd/pagemap: pre-existing fixes" from
   Kiryl Shutsemau fixes a bunch of minor issues in the
   userfaultfd/pagemap, all of which were flagged by Sashiko review of
   proposed new material.
 
 - The 5 patch series "mm/sparse-vmemmap: Provide generic
   vmemmap_set_pmd() and vmemmap_check_pmd()" from Muchun Song provides
   generic versions of these two functions so the four arch-specific
   implementations can be removed.
 
 - The 2 patch series "mm/swap, PM: hibernate: fix swapoff race in
   uswsusp by pinning swap device" from Youngjun Park addresses a
   uswsusp-vs-swapoff race and reduces the swap device reference
   taking/releasing frequency.
 
 - The 2 patch series "mm/hmm: A fix and a selftest" from Dev Jain does
   as claimed.

Linus Torvalds
c98d767b34 Arm: 
"This is a bit of an odd merge window on the KVM/arm64 front. There is
 absolutely no new feature in the pull request. It is purely fixes,
 because it is simply becoming too hard to review new stuff when so
 many AI-fuelled fixes hit the list".
 
 - Significant cleanup of the vgic-v5 PPI support which was merged in
   7.1. This makes the code more maintainable, and squashes a couple
   of bugs in the meantime.
 
 - Set of fixes for the handling of the MMU in an NV context,
   particularly VNCR-triggered faults. S1POE support is fixed
   as well.
 
 - Large set of pKVM fixes, mostly addressing recurring issues
   around hypervisor tracking of donated pages in obscure cases
   where the donation could fail and leave things in a bizarre
   state.
 
 - Fixes for the so-called "lazy vgic init", which resulted in
   sleeping operations in non-preemptible sections. This turned
   out to be far more invasive than initially expected...
 
 - Reduce the overhead of L1/L2 context switch by not touching
   the FP registers.
 
 - Fix the way non-implemented page sizes are dealt with when
   a guest insist on using them for S2 translation.
 
 - The usual set of low-impact fixes and cleanups all over the map.
 
 Loongarch:
 
 - On a request for lazy FPU load, load all FPU state that the VM
   supports instead of enabling only the part (FPU, LSX or LASX)
   that caused the FPU load request.
 
 - Some enhancements about interrupt injection.
 
 - Some bug fixes and other small changes.
 
 RISC-V:
 
 - Batch G-stage TLB flushes for GPA range based page table updates
 
 - Convert HGEI line management to fully per-HART
 
 - Fix missing CSR dirty marking when FWFT state updated via ONE_REG
 
 - Fix stale FWFT feature exposure to Guest/VM
 
 - Speed up dirty logging write faults using MMU rwlock and atomic
   PTE updates using cmpxchg() for permission-only changes
 
 - Use flexible array for APLIC IRQ state
 
 - Use kvm_slot_dirty_track_enabled() for logging enable check on
   a memslot
 
 - Avoid skipping valid pages in kvm_riscv_gstage_wp_range()
 
 - Avoid skipping valid pages in kvm_riscv_gstage_unmap_range()
 
 - Use endian-specific __lelong for NACL shared memory
 
 S390:
 
 - KVM_PRE_FAULT_MEMORY support
 
 - Support for 2G hugepages
 
 - Support for the ASTFLEIE 2 facility
 
 - Support for fast inject using kvm_arch_set_irq_inatomic
 
 - Fix potential leak of uninitialized bytes
 
 - A few more misc gmap fixes.
 
 x86:
 
 - Generic support for the more granular permissions allowed by EPT,
   namely "read" (which was previously usurping the U bit) and
   separate execution bits for kernel and userspace.
 
 - Do not assume that all page tables start with U=1/W=1/NX=0 at the
   root, as AMD GMET needs to have U=0 at the root.
 
 - Introduce common assembly macros for use within Intel and AMD
   vendor-specific vmentry code.  This touches the SPEC_CTRL handling,
   which is now entirely done in assembly for Intel (by reusing the
   AMD code that already existed), and register save/restore which
   uses some macro magic to compute the offsets in the struct.  Both
   of these are preparatory changes for upcoming APX support.
 
 - Clean up KVM's register tracking and storage, primarily to prepare for
   APX support, which expands the maximum number of GPRs from 16 to 32.
 
 - Keep a single copy of the PDPTRs rather than two, since architecturally
   there is just one.
 
 - Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor code
   gets a chance to handle things like reaping the PML buffer.
 
 - Update KVM's view of PV async enabling if and only if the MSR write fully
   succeeds.
 
 - Fix a variety of issues where the emulator doesn't honor guest-debug state,
   and clean up related code along the way.
 
 - Synthesize EPT Violation and #NPF "error code" bits when injecting faults
   into L1 that didn't originate in hardware (in which case the VMCS/VMCB
   doesn't hold relevant information).
 
 - Add support for virtualizing (well, emulating) AMD's flavor of CPL>0 CPUID
   faulting.
 
 - Clean up the GPR APIs so that KVM's use of "raw" is consistent, and fix a
   variety of minor bugs along the way.
 
 - Fix an OOB memory access due to not checking the VP ID when handling a
   Hyper-V PV TLB flush for L2.
 
 - Fix a bug in the mediated PMU's handling of fixed counters that allowed the
   guest to bypass the PMU event filter.
 
 - Allow userspace to return EAGAIN when handling SNP and TDX hypercalls, so
   the KVM can forward a "retry" status code to the guest, and reserve all
   unused error codes for future usage.
 
 - Overhaul the TDP MMU => S-EPT code to move as much S-EPT specific logic as
   possible into the TDX code, and to funnel (almost) all S-EPT updates into
   a single chokepoint.  The motivation is largely to prepare for upcoming
   Dynamic PAMT support, but the cleanups are nice to have on their own.
 
 - Plug a hole in shadow page table handling, where KVM fails to recursively
   zap nested EPT/NPT shadow page tables when the nested hypervisor tears
   down its own EPT/NPT page tables from the bottom up
 
 x86 (Intel):
 
 - Support for nested MBEC (Mode-Based Execute Control), see above in the
   generic section; also run with MBEC enabled even for non-nested mode.
 
 - Use the kernel's "enum pg_level" in the TDX APIs instead of the TDX-Module's
   level definitions (which are 0-based).
 
 - Rework the TDX memory APIs to not require/assume that guest memory is

 - Fix a largely benign bug where KVM TDX would incorrectly state it could

 - Use the "safe" WRMSR API when proxying LBR MSR writes as the to-be-written
   value is guest controlled and completely unvalidated.
 
 x86 (AMD):
 
 - Support for nested GMET (Guest Mode Execution Trap), see above in the
   generic section; also run with GMET enabled even for non-nested mode.

   already merged into 7.1-rc.
 
 - Ensure KVM's copy of CR0 and CR3 are up-to-date prior to invoking
   fastpath handlers.
 
 - Add support for virtualizing gPAT (KVM previously just used L1's PAT when
   running L2).
 
 - Fix goofs where KVM mishandles side effects (e.g. single-step and PMC
   updates) when emulating VMRUN.
 
 - Fix a variety of bugs in AVIC's handling of x2APIC MSR interception, most
   notably where KVM didn't disable interception of IRR, ISR, and TMR regs.

   the kernel's nomenclature, e.g. for mmu_notifiers.
 
 - Use guard() to cleanup up various KVM+VFIO flows.
 
 - Minor cleanups.
 
 guest_memfd:
 
 - Return -EEXIST instead of -EINVAL if userspace attempts to bind a gmem
   range to multiple memslots, and fix the test that was supposed to ensure
   KVM returns -EEXIST.
 
 - Treat memslot binding offsets and sizes as unsigned values to fix a bug
   where KVM interprets a large "offset + size" as a negative value and allows
   a nonsensical offset.
 
 - Use the inode number instead of the page offset for the NUMA interleaving
   index to fix a bug where the effective index would jump by two for
   consecutive pages (the caller also adds in the page offset).
 
 Selftests:
 
 - Randomize the dirty log test's delay when reaping the bitmap on the first
   pass, as always waiting only 1ms hid a KVM RISC-V bug as the test reaped the
   bitmap before KVM could build up enough state to hit the bug.
 
 - A pile of one-off fixes and cleanups.

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

Pull kvm updates from Paolo Bonzini:
 "arm64:

     This is a bit of an odd merge window on the KVM/arm64 front. There
     is absolutely no new feature in the pull request. It is purely
     fixes, because it is simply becoming too hard to review new stuff
     when so many AI-fuelled fixes hit the list.

   - Significant cleanup of the vgic-v5 PPI support which was merged in
     7.1. This makes the code more maintainable, and squashes a couple
     of bugs in the meantime

   - Set of fixes for the handling of the MMU in an NV context,
     particularly VNCR-triggered faults. S1POE support is fixed as well

   - Large set of pKVM fixes, mostly addressing recurring issues around
     hypervisor tracking of donated pages in obscure cases where the
     donation could fail and leave things in a bizarre state

   - Fixes for the so-called "lazy vgic init", which resulted in
     sleeping operations in non-preemptible sections. This turned out to
     be far more invasive than initially expected..

   - Reduce the overhead of L1/L2 context switch by not touching the FP
     registers

   - Fix the way non-implemented page sizes are dealt with when a guest
     insist on using them for S2 translation

   - The usual set of low-impact fixes and cleanups all over the map

  Loongarch:

   - On a request for lazy FPU load, load all FPU state that the VM
     supports instead of enabling only the part (FPU, LSX or LASX) that
     caused the FPU load request

   - Some enhancements about interrupt injection

   - Some bug fixes and other small changes

  RISC-V:

   - Batch G-stage TLB flushes for GPA range based page table updates

   - Convert HGEI line management to fully per-HART

   - Fix missing CSR dirty marking when FWFT state updated via ONE_REG

   - Fix stale FWFT feature exposure to Guest/VM

   - Speed up dirty logging write faults using MMU rwlock and atomic PTE
     updates using cmpxchg() for permission-only changes

   - Use flexible array for APLIC IRQ state

   - Use kvm_slot_dirty_track_enabled() for logging enable check on a
     memslot

   - Avoid skipping valid pages in kvm_riscv_gstage_wp_range()

   - Avoid skipping valid pages in kvm_riscv_gstage_unmap_range()

   - Use endian-specific __lelong for NACL shared memory

  S390:

   - KVM_PRE_FAULT_MEMORY support

   - Support for 2G hugepages

   - Support for the ASTFLEIE 2 facility

   - Support for fast inject using kvm_arch_set_irq_inatomic

   - Fix potential leak of uninitialized bytes

   - A few more misc gmap fixes

  x86:

   - Generic support for the more granular permissions allowed by EPT,
     namely "read" (which was previously usurping the U bit) and
     separate execution bits for kernel and userspace

   - Do not assume that all page tables start with U=1/W=1/NX=0 at the
     root, as AMD GMET needs to have U=0 at the root

   - Introduce common assembly macros for use within Intel and AMD
     vendor-specific vmentry code. This touches the SPEC_CTRL handling,
     which is now entirely done in assembly for Intel (by reusing the
     AMD code that already existed), and register save/restore which
     uses some macro magic to compute the offsets in the struct. Both of
     these are preparatory changes for upcoming APX support

   - Clean up KVM's register tracking and storage, primarily to prepare
     for APX support, which expands the maximum number of GPRs from 16
     to 32

   - Keep a single copy of the PDPTRs rather than two, since
     architecturally there is just one

   - Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor
     code gets a chance to handle things like reaping the PML buffer

   - Update KVM's view of PV async enabling if and only if the MSR write
     fully succeeds

   - Fix a variety of issues where the emulator doesn't honor
     guest-debug state, and clean up related code along the way

   - Synthesize EPT Violation and #NPF "error code" bits when injecting
     faults into L1 that didn't originate in hardware (in which case the
     VMCS/VMCB doesn't hold relevant information)

   - Add support for virtualizing (well, emulating) AMD's flavor of
     CPL>0 CPUID faulting

   - Clean up the GPR APIs so that KVM's use of "raw" is consistent, and
     fix a variety of minor bugs along the way

   - Fix an OOB memory access due to not checking the VP ID when
     handling a Hyper-V PV TLB flush for L2

   - Fix a bug in the mediated PMU's handling of fixed counters that
     allowed the guest to bypass the PMU event filter

   - Allow userspace to return EAGAIN when handling SNP and TDX
     hypercalls, so the KVM can forward a "retry" status code to the
     guest, and reserve all unused error codes for future usage

   - Overhaul the TDP MMU => S-EPT code to move as much S-EPT specific
     logic as possible into the TDX code, and to funnel (almost) all
     S-EPT updates into a single chokepoint. The motivation is largely
     to prepare for upcoming Dynamic PAMT support, but the cleanups are
     nice to have on their own

   - Plug a hole in shadow page table handling, where KVM fails to
     recursively zap nested EPT/NPT shadow page tables when the nested
     hypervisor tears down its own EPT/NPT page tables from the bottom
     up

  x86 (Intel):

   - Support for nested MBEC (Mode-Based Execute Control), see above in
     the generic section; also run with MBEC enabled even for non-nested
     mode

   - Use the kernel's "enum pg_level" in the TDX APIs instead of the
     TDX-Module's level definitions (which are 0-based)

   - Rework the TDX memory APIs to not require/assume that guest memory
     is backed by "struct page" (in prepartion for guest_memfd hugepage
     support)

   - Fix a largely benign bug where KVM TDX would incorrectly state it
     could emulate several x2APIC MSRs

   - Use the "safe" WRMSR API when proxying LBR MSR writes as the
     to-be-written value is guest controlled and completely unvalidated

  x86 (AMD):

   - Support for nested GMET (Guest Mode Execution Trap), see above in
     the generic section; also run with GMET enabled even for non-nested
     mode

   - Fixes and minor cleanups to GHCB handling, on top of the earlier

     interception, most notably where KVM didn't disable interception of

f32a375ecc RISC-V updates for v7.2 
- Prevent get_free_mem_region() from returning regions that are
   unmappable in certain circumstances by defining
   DIRECT_MAP_PHYSMEM_END for RISC-V
 
 - Fix an early boot problem with kexec_file when the amount of
   installed physical memory installed on the system exceeds the direct
   map size, which is possible in certain RISC-V virtual memory modes
 
 - Unconditionally sfence.vma in the new vmalloc area handling code in
   the page fault handler, since even the presence of Svvptc doesn't
   guarantee that the CPU won't immediately fault again after the
   exception handler completes and subsequently crash
 
 - Fix ftrace_graph_ret_addr() to use the correct task pointer
   (aligning with what other architectures do)
 
 - Fix the misaligned access performance checking code in cases when
   performance is specified on the kernel command line and when CPUs
   have been brought offline and back online
 
 - Get rid of a bogus address offset in the non-frame-pointer version
   of walk_stackframe(), aligning it with the frame pointer-based code
 
 - Fix a RISC-V kfence issue causing bogus use-after-free warnings
 
 - Add ARCH_HAS_CC_CAN_LINK for RISC-V, which needs different compiler
   command line flags than other architectures
 
 - Implement _THIS_IP_ using RISC-V-specific assembly, which seems to
   be less brittle (from a compiler point of view) than taking the
   address of a label
 
 - Reduce kernel startup overhead by defining
   HAVE_BUILDTIME_MCOUNT_SORT, since arch/riscv meets all the
   requirements
 
 - Patch the CFI vDSO during alternatives processing, not only the
   standard vDSO
 
 - Fix a potential memory leak in the cacheinfo code
 
 - Clean up kernel/setup.c:add_resource() to pass along the return
   value from insert_resource() and to improve the display of
   resource ranges
 
 - Clean up our purgatory.[ch] by aligning our purgatory() prototype
   to what's in arch/x86, and by cleaning up verify_sha256_digest()
 
 - Clean up cpu_is_stopped() to align its function a little more
   closely to its name
 
 - Replace some unbounded string function usage in get_early_cmdline()
   and the ptdump code with strscpy()
 
 - Replace sprintf() with sysfs_emit() in cpu_show_ghostwrite() for
   safer bounds checking
 
 - Standardize how compiler output flags are specified in the RISC-V
   kselftests, aligning them with what other architectures do
 
 - Use the Linux-generic cmp_int() macro in place of an open-coded
   "cmp_3way()" macro in kernel/module-sections.c
 
 - Panic early in boot if IRQ handler stacks can't be allocated rather
   than pretending to continue normally
 
 - Add support for Eswin SoCs in the RISC-V defconfig
 
 - Remove some unnecessary conditionals in sbi_hsm_hart_{start,stop}()
 
 - Clean up some Kconfig infelicities found by Kconfirm
 
 - Replace an open-coded version of min() in the kexec_elf code with
   the standard min() function

Pull RISC-V updates from Paul Walmsley:

 - Prevent get_free_mem_region() from returning regions that are
   unmappable in certain circumstances by defining
   DIRECT_MAP_PHYSMEM_END for RISC-V

 - Fix an early boot problem with kexec_file when the amount of
   installed physical memory installed on the system exceeds the direct
   map size, which is possible in certain RISC-V virtual memory modes

 - Unconditionally sfence.vma in the new vmalloc area handling code in
   the page fault handler, since even the presence of Svvptc doesn't
   guarantee that the CPU won't immediately fault again after the
   exception handler completes and subsequently crash

 - Fix ftrace_graph_ret_addr() to use the correct task pointer (aligning
   with what other architectures do)

 - Fix the misaligned access performance checking code in cases when
   performance is specified on the kernel command line and when CPUs
   have been brought offline and back online

 - Get rid of a bogus address offset in the non-frame-pointer version of
   walk_stackframe(), aligning it with the frame pointer-based code

 - Fix a RISC-V kfence issue causing bogus use-after-free warnings

 - Add ARCH_HAS_CC_CAN_LINK for RISC-V, which needs different compiler
   command line flags than other architectures

 - Implement _THIS_IP_ using RISC-V-specific assembly, which seems to be
   less brittle (from a compiler point of view) than taking the address
   of a label

 - Reduce kernel startup overhead by defining
   HAVE_BUILDTIME_MCOUNT_SORT, since arch/riscv meets all the
   requirements

 - Patch the CFI vDSO during alternatives processing, not only the
   standard vDSO

 - Fix a potential memory leak in the cacheinfo code

 - Clean up kernel/setup.c:add_resource() to pass along the return value
   from insert_resource() and to improve the display of resource ranges

 - Clean up our purgatory.[ch] by aligning our purgatory() prototype to
   what's in arch/x86, and by cleaning up verify_sha256_digest()

 - Clean up cpu_is_stopped() to align its function a little more closely
   to its name

 - Replace some unbounded string function usage in get_early_cmdline()
   and the ptdump code with strscpy()

 - Replace sprintf() with sysfs_emit() in cpu_show_ghostwrite() for
   safer bounds checking

 - Standardize how compiler output flags are specified in the RISC-V
   kselftests, aligning them with what other architectures do

 - Use the Linux-generic cmp_int() macro in place of an open-coded
   "cmp_3way()" macro in kernel/module-sections.c

 - Panic early in boot if IRQ handler stacks can't be allocated rather
   than pretending to continue normally

 - Add support for Eswin SoCs in the RISC-V defconfig

 - Remove some unnecessary conditionals in sbi_hsm_hart_{start,stop}()

 - Clean up some Kconfig infelicities found by Kconfirm

 - Replace an open-coded version of min() in the kexec_elf code with
   the standard min() function

9ecfb2f728 ring-buffer: Updates for v7.2: 
- Do not invalidate entire buffer for invalid sub-buffers
 
   For the persistent ring buffer, if one sub-buffer is found to be invalid,
   it invalidates the entire per CPU ring buffer. This can lose a lot of
   valuable data if there's some corruption with the writes to the buffer not
   syncing properly on a hard crash. Instead, if a sub-buffer is found to be
   invalid, simply zero it out and mark it for "missed events".
 
   When the persistent ring buffer is read and a sub-buffer that was cleared
   due to being invalid on boot up is discovered, the output will show
   "[LOST EVENTS]" to let the user know that events were missing at that
   location. Displaying the events from valid buffers can still be useful.
 
 - Add a test to be able to test corrupted sub-buffers
 
   If a persistent ring buffer is created as "ptraingtest" and the new config
   that adds the test is enabled, when a panic happens, the kernel will
   randomly corrupt one of the per CPU ring buffers. On boot up, the
   sub-buffers with the corruption should be cleared and flagged. When
   reading this buffer, the missed events should should [LOST EVENTS].
 
 - Add commit number in the sub-buffer meta debug info
 
   The commit is used to know the content of a meta page. Add it to the
   buffer_meta file that is shown for each per CPU buffer.
 
 - Clean up the persistent ring buffer validation code
 
   Add some helper functions and make variable names more consistent.

23b5d045ae tracing: Updates for v7.2: 
- Remove a redundant IS_ERR() check
 
   trace_pipe_open() already checks for IS_ERR() and does it again in the
   return path. Remove the return check.
 
 - Export seq_buf_putmem_hex() to allow kunit tests against them
 
   To add Kunit tests on seq_buf_putmem_hex(), it needs to be exported.
 
 - Replace strcat() and strcpy() with seq_buf() logic
 
   The code for synthetic events uses a series of strcat() and strcpy() which
   can be error prone. Replace them with seq_buf() logic that does all the
   necessary bound checking.
 
 - Add a lockdep rcu_is_watching() to trace_##event##_enabled() call
 
   The trace_##event##_enabled() is a static branch that is true if the
   "event" is enabled. But this can hide bugs if this logic is in a location
   where RCU is disabled and not "watching". It would only trigger if lockdep
   is enabled and the event is enabled.
 
   Add a "rcu_is_watching()" warning if lockdep is enabled in that helper
   function to trigger regardless if the event is enabled or not.
 
 - Remove the local variable in the trace_printk() macro
 
   For name space integrity, remove the _______STR variable in the
   trace_printk() macro for using the sizeof() macro directly.
 
 - Use guard()s for the trace_recursion_record.c file
 
 - Fix typo in a comment of eventfs_callback() kerneldoc
 
 - Use trace_call__##event() in events called within trace_##event##_enabled()
 
   A couple of events are called within an if block guarded by
   trace_##event##_enabled(). That is a static key that is only enabled when
   the event is enabled. The trace_call_##event() calls the tracepoint code
   directly without adding a redundant static key for that check.
 
 - Allow perf to read synthetic events
 
   Currently, perf does not have the ability to enable a synthetic event. If
   it does, it will either cause a kernel warning or error with "No such
   device". Synthetic events are not much different than kprobes and perf can
   handle fine with a few modifications.
 
 - Replace printk(KERN_WARNING ...) with pr_warn()
 
 - Replace krealloc() on an array with krealloc_array()
 
 - Fix README file path name for synthetic events
 
 - Change tracing_map tracing_map_array to use a flexible array
 
   Instead of allocating a separate pointer to hold the pages field of
   tracing_map_array, allocate the pages field as a flexible array when
   allocating the structure.
 
 - Fold trace_iterator_increment() into trace_find_next_entry_inc()
 
   The function trace_iterator_increment() was only used by
   trace_find_next_entry_inc(). It's not big enough to be a helper function
   for one user. Fold it into its caller.
 
 - Make field_var_str field a flexible array of hist_elt_data
 
   Instead of allocating a separate pointer for the field_var_str array of
   the hist_elt_data structure, allocate it as a flexible array when
   allocating the structure.
 
 - Disable KCOV for trace_irqsoff.c
 
   Like trace_preemptirq.c, trace_irqsoff.c has code that will crash when
   KCOV is enabled on ARM. The irqsoff tracing can be called on ARM because
   the irqsoff tracing code can be run from early interrupt code and produce
   coverage unrelated to syscall inputs.
 
 - Fix warning in __unregister_ftrace_function() called by perf
 
   Perf calls unregister_ftrace_function() without checking if its ftrace_ops
   has already been unregistered. There's an error path where on clean up it
   will unregister the ftrace_ops even if it wasn't registered and causes a
   warning.

3dc7c00116 NFSD 7.2 Release Notes 
Jeff Layton wired up netlink upcalls for the auth.unix.ip and
 auth.unix.gid caches in SunRPC and the svc_export and nfsd.fh
 caches in NFSD. The new kernel-user API is more extensible and
 lays the groundwork for retiring the old pipe interface.
 
 The default NFS r/w block size rises to 4MB on hosts with at least
 16GB of RAM, reducing per-RPC overhead on fast networks. Smaller
 machines keep their previously computed default, and the value
 remains tunable through /proc/fs/nfsd/max_block_size.
 
 Chuck Lever converted the server's RPCSEC GSS Kerberos code to the
 kernel's shared crypto/krb5 library. The conversion retires and
 removes SunRPC's bespoke implementation of Kerberos v5, but keeps
 RPCSEC GSS-API.
 
 Continuing the xdrgen migration that converted the NLMv4 server XDR
 layer in v7.1, Chuck Lever converted the NLM version 3 server-side
 XDR layer from hand-written C to xdrgen-generated code. As with the
 NLMv4 conversion in v7.1, the goals are improved memory safety,
 lower maintenance burden, and groundwork for generation of Rust code
 for this layer instead of C.
 
 Chuck Lever fixed an issue where lingering NFSv4 state pins a
 mounted file system after it is unexported. A new netlink-based
 mechanism can now release NLM locks and NFSv4 state by client
 address, by filesystem, and by export. Now an administrator can
 quiesce an export cleanly before unmounting it.
 
 The remaining patches are bug fixes, clean-ups, and minor
 optimizations, including a batch of memory-leak and use-after-free
 fixes in the ACL, lockd, and TLS handshake paths, many of them
 reported by Chris Mason. Sincere thanks to all contributors,
 reviewers, testers, and bug reporters who participated in the v7.2
 NFSD development cycle.

Pull devicetree updates from Rob Herring:
 "DT core:

   - Add support for handling multiple cells in "iommu-map" entries

   - Support only 1 entry in /reserved-memory "reg" entries. Support for
     more than 1 entry has been broken

   - Fix a UAF on alloc_reserved_mem_array() failure

   - Make "ibm,phandle" handling logic specific to PPC

   - Use memcpy() instead of strcpy() for known length strings

   - Ensure __of_find_n_match_cpu_property() handles malformed "reg"
     entries

   - Add various checks that expected strings are strings before
     accessing them

   - Drop redundant memset() when unflattening DT

  DT bindings:

   - Add a DTS style checker. Currently hooked up to dt_binding_check to
     check examples

   - Convert st,nomadik platform, ti,omap-dmm, and ti,irq-crossbar
     bindings to DT schema

   - Add Apple System Management Controller hwmon, Qualcomm Hamoa
     Embedded Controller, Qualcomm IPQ6018 PWM controller, fsl,mc1323,
     Samsung SOFEF01-M DDIC panel, Freescale i.MX53 Television Encoder,
     Samsung S2M series PMIC extcon, and MT6365 PMIC AuxADC schemas

   - Extend bindings for QCom Maili and Nord PDC, QCom Hali fastrpc,
     qcom,eliza-imem, qcom,oryon-1-5 CPU, and MT6365 Keys

   - Consolidate "sram" property definitions

   - Fix constraints on "nvmem" properties which only contain phandles
     and no arg cells

   - Another pass of fixing "phandle-array" constraints

   - Add Gira vendor prefix"

3dc0df0339 VFIO updates for v7.2-rc1 
- Fix out-of-tree vfio selftest builds with make O=. (Jason Gunthorpe)
 
  - Allow vfio selftests to build when ARCH=x86 is used for 64-bit x86
    builds. (David Matlack)
 
  - Tighten vfio selftest infrastructure with stricter builds, safer
    path handling, sysfs helpers, and reusable device/VF-token setup.
    Build on that to add the SR-IOV UAPI selftest across supported
    IOMMU modes. (Raghavendra Rao Ananta)
 
  - Conclude earlier vfio PCI BAR work already taken as v7.1 fixes by
    replacing vfio_pci_core_setup_barmap() and direct barmap[] access
    with vfio_pci_core_get_iomap().  Fix resulting sparse warnings.
    (Matt Evans)
 
  - Simplify hisi_acc vfio-pci variant driver device-info reads by
    using the mailbox's new direct command-based read helper.
    (Weili Qian)
 
  - Avoid duplicate reset handling in the Xe vfio-pci variant driver
    reset-done path. (GuoHan Zhao)
 
  - Resolve a lockdep circular dependency splat by tracking active
    VFs with a private sriov_active flag rather than calling
    pci_num_vf() under memory_lock. (Raghavendra Rao Ananta)
 
  - Add CXL DVSEC-based readiness polling for Blackwell-Next in the
    nvgrace-gpu vfio-pci variant driver, including interruptible,
    lockless waits to support worst case spec defined timeouts.
    (Ankit Agrawal)
 
  - Prevent vfio_mig_get_next_state() from spinning forever on blocked
    migration state transition. (Junrui Luo)
 
  - Fix a qat vfio variant driver migration resume race by taking the
    migration file lock before boundary checks. (Giovanni Cabiddu)
 
  - Add explicit dependencies between vfio selftest output object files
    and output directories to ensure directories are always created.

aab799b1bd soc: devicetree updates for 7.2 
There are fewer devicetree updates this time that the last few ones, with
 five SoC types getting added:
 
  - Qualcomm Dragonwing IPQ9650 is a new wireless networking SoC using
    four Cortex-A55 and one Cortex-A78 core, which is a significant
    upgrade from older generations
 
  - ZTE zx297520v3 is an older low-end wireless SoC using a single
    Cortex-A53 core, which so far can only run 32-bit kernels.  This brings
    back the ZX family of chips that was removed in 2021 after support
    for the original zx296702 and zx296718 chips was never completed.
 
  - Renesas R-Car M3Le (R8A779MD) is a variant of the R-Car M3-N (R8A77965)
    automotive SoC.
 
  - Apple t8122 (M3) is the 2023 generation of their laptop SoCs,
    which has now been reverse-engineered to the point of having initial
    kernel support for five laptop models.
 
  - ASPEED AST27xx is their first baseboard managment controller using
    a 64-bit core, the Cortex-A35, following earlier generations using
    ARMv5/v6/v7 CPUs.
 
 These all come with one or more initial boards, and in total there
 are 39 new boards getting added across SoC families, including:
 
  - Two NAS boxes using the old Cortina Systems Gemini SoC based on
    an ARMv4 FA526 CPU core
 
  - 18 industrial embedded boards using NXP i.MX6/8/9 and LX2160A
    SoCs from Variscite, Toradex and SolidRun, plus a number of
    overlays for combinations with additional boards
 
  - One new carrier board and SoM using TI K3 AM62x, in addition to
    new overlays for older SoMs
 
  - Two new boards using Spacemit K3 (no relation with TI) RISC-V
    SoCs.
 
  - Three phones from Google, Nothing and Motorola, all using Qualcomm
    Snapdragon SoCs
 
  - AST26xx BMC support for two server boards
 
 While there is still a significant number of patches improving hardware
 support for the existing boards across vendors (NXP, Qualcomm, Renesas,
 Rockchips, Mediatek, ...), a much smaller number of cleanups and warning
 fixes have made it in this time.

   Prior to this fix we were unable to remove an executable file watch

5b33fc6492 sched_ext: Changes for v7.2 
This depends on the BPF arena work in bpf-next and should be pulled after
 it. for-7.1-fixes was merged in a few times to avoid conflicts with the
 feature changes.
 
 - Most of this continues the in-development sub-scheduler support, which
   lets a root BPF scheduler delegate to nested sub-schedulers. The
   dispatch-path building blocks landed in 7.1. A follow-up patchset in
   development will complete enqueue-path support for hierarchical
   scheduling. This cycle adds most of that infrastructure:
 
   - Topological CPU IDs (cids): a dense, topology-ordered CPU numbering
     where the CPUs of a core, LLC, or NUMA node form contiguous ranges,
     so a topology unit becomes a (start, length) slice. Raw CPU numbers
     are sparse and don't track topological closeness, which makes them
     clumsy for sharding work across sub-schedulers and awkward in BPF.
 
   - cmask: bitmaps windowed over a slice of cid space, so a sub-scheduler
     can track, for example, the idle cids of its shard without a full
     NR_CPUS cpumask.
 
   - A struct_ops variant that cid-form sub-schedulers register with,
     along with the cid-form kfuncs they call.
 
   - BPF arena integration, which sub-scheduler support is built on. The
     bpf-next additions let the kernel read and write the BPF scheduler's
     arena directly, turning it into a real kernel/BPF shared-memory
     channel. Shared state like the per-CPU cmask now lives there.
 
   - scx_qmap is reworked to exercise the new arena and cid interfaces.
 
 - Exit-dump improvements: dump the faulting CPU first, expose the exit
   CPU to BPF and userspace, and normalize the dump header.
 
 - Misc kfuncs and cleanups: a task-ID lookup kfunc, __printf checking on
   the error and dump formatters, header reorganization, and assorted
   fixes.

  lets a root BPF scheduler delegate to nested sub-schedulers. The
  dispatch-path building blocks landed in 7.1. A follow-up patchset in
  development will complete enqueue-path support for hierarchical
  scheduling. This cycle adds most of that infrastructure:

   - Topological CPU IDs (cids): a dense, topology-ordered CPU numbering
     where the CPUs of a core, LLC, or NUMA node form contiguous ranges,
     so a topology unit becomes a (start, length) slice. Raw CPU numbers
     are sparse and don't track topological closeness, which makes them
     clumsy for sharding work across sub-schedulers and awkward in BPF.

   - cmask: bitmaps windowed over a slice of cid space, so a
     sub-scheduler can track, for example, the idle cids of its shard
     without a full NR_CPUS cpumask.

   - A struct_ops variant that cid-form sub-schedulers register with,
     along with the cid-form kfuncs they call.

   - BPF arena integration, which sub-scheduler support is built on. The
     bpf-next additions let the kernel read and write the BPF
     scheduler's arena directly, turning it into a real kernel/BPF
     shared-memory channel. Shared state like the per-CPU cmask now
     lives there.

   - scx_qmap is reworked to exercise the new arena and cid interfaces.

  Additionally:

   - Exit-dump improvements: dump the faulting CPU first, expose the
     exit CPU to BPF and userspace, and normalize the dump header.

   - Misc kfuncs and cleanups: a task-ID lookup kfunc, __printf checking
     on the error and dump formatters, header reorganization, and
     assorted fixes"

83476cc97b cgroup: Changes for v7.2 
- Last cycle deferred css teardown on cgroup removal until the cgroup
   depopulated, so a css is not taken offline while tasks can still
   reference it. Disabling a controller through cgroup.subtree_control
   still had the same problem. This reworks the deferral from per-cgroup
   to per-css so that path is covered too.
 
 - New RDMA controller monitoring files: rdma.peak for per-device peak
   usage and rdma.events / rdma.events.local for resource-limit
   exhaustion. The max-limit parser was rewritten, fixing two input
   parsing bugs.
 
 - cpuset: fix a sched-domain leak on the domain-rebuild failure path and
   skip a redundant hardwall ancestor scan on v2.
 
 - Misc: pair the remaining lockless cgroup.max.* reads with WRITE_ONCE,
   assorted selftest robustness fixes, and doc path corrections.

8479bb8c44 Modules changes for v7.2-rc1 
- Add a missing return value check for module_extend_max_pages()
   to prevent a kernel oops on memory allocation failure.
 
 - Force sh_addr to 0 for architecture-specific module sections on
   arm, arm64, m68k, and riscv. This prevents non-zero section
   addresses when linking modules with ld.bfd -r, which may cause
   tools to misbehave and result in worse compressibility.
 
 - Replace pr_warn! with pr_warn_once! for set_param null pointer
   warnings in Rust abstractions, now that the _once variant is
   available.
 
 Note that as part of our maintainer rotation, Petr Pavlu will be
 taking over module subsystem pull requests for the next six months.

c454531af7 dt-bindings: mfd: syscon: Revert renesas,r9a08g046-lvds-cmn 
Revert commit 51284d8b1dbc ("dt-bindings: mfd: syscon: Document the
LVDS_CMN syscon for the RZ/G3L") because it is completely not matching
reality and clearly incorrect in respect of renesas,r9a08g046-lvds-cmn.

It wasn't ever build-tested by author on their DTS, either.

The documented renesas,r9a08g046-lvds-cmn compatible clearly disallows
any children and simple-mfd fallback, however its only use in original
patchset is with simple-mfd and children, so this could have never
worked.

The st,stmpe-pwm binding is already covered by the MFD schema in
Documentation/devicetree/bindings/mfd/st,stmpe.yaml. However, the
PWM subnode was missing a 'required' properties block. This allowed
Device Tree nodes to pass validation even if the 'compatible'
string was omitted. This omission could lead to probe failures
at runtime.

Fix the schema by adding the missing 'required' block.
