These changes establish a cleaner foundation for future work that will unify virtual page offset indexing for all anonymous and CoW'd folios. - "mm: handle device-private PMDs in walk callbacks" (Usama Arif) Address kernel panics and state corruption caused by MM walk callbacks reaching non-present device-private PMD swap entries created during HMM migrations It ensures that functions which acquire pmd_trans_huge_lock() properly recognize device-private PMDs instead of assuming a present THP or a standard migration entry. - "mm/rmap: Refactor try_to_unmap_one" (Dev Jain) Refactor try_to_unmap_one by modularizing Hugetlb, anonymous-lazyfree, and anonymous-swapbacked logic into dedicated functions, laying the structural groundwork for batched anonymous large folio unmapping. - "Docs/ABI/damon: sysfs ABI document fixes and additions" (Song Hu) Fix typos and fills in missing entries in the DAMON sysfs ABI document - "dax/kmem: atomic whole-device hotplug via sysfs" (Gregory Price) Introduce an atomic sysfs state attribute and supporting DAX/MM infrastructure to prevent userland races when offlining and removing entire memory regions By adding an unplugged state alongside standard online modes, it enables whole-device atomic hotplug control while preserving backward compatibility. - "mm: convert more vm_flags_t users to vma_flags_t" (Lorenzo Stoakes) Continue transitioning the kernel from the deprecated vm_flags_t type to vma_flags_t across core memory management infrastructure. It replaces legacy type usage in core functions such as do_mmap(), unmapped area allocation, mm->def_vma_flags, and VMA operations like mlock, mprotect, and mremap. - "Two small patches to clean up mm/mm_slot.h" (xu xin) Refactor mm_slot.h by introducing mm_slot_remove() to unify duplicate slot deletion sequences in khugepaged and KSM. It also adds code documentation explaining why mm_slot_lookup and mm_slot_insert must remain as preprocessor macros rather than static inline functions. - "mm/damon/core: hide core-private struct fields" (SJ Park) Clean up DAMON core structures by consistently marking internal-only fields with private: comment tags to prevent improper direct access from outer layers. It enforces encapsulation across core structures including damon_region, damon_target, and damon_ctx and updates DAMON_SYSFS to interact through approved access APIs instead of exposing raw struct members. - "mm/damon: unurgent fixes for infinite loop, NULL de-ref and races" (SJ Park) Address potential infinite loops, NULL dereferences, and race conditions identified in DAMON It fixes an infinite loop triggered by extreme user configurations, a NULL pointer dereference within unit tests and minor monitoring accuracy degradation caused by subtle runtime races. - "mm/page_alloc: fixes for free_pages_nolock() on RT/UP" (Brendan Jackman) Fix an NMI safety flaw in __free_frozen_pages() where freeing pages on non-SMP or PREEMPT_RT kernels can bypass can_spin_trylock() checks via non-PCP or isolated migration paths. It also resolves potential kernel crashes and privilege escalation risks triggered when BPF tracing runs in NMI context alongside memory hotplug or large allocation frees. - "mm/page_alloc: couple of followups for recent cleanups" (Brendan Jackman) Clean up and update page allocator nomenclature, documentation, and debug assertions. It aligns internal FPI_ flags with the public "nolock" naming convention, removes outdated internal implementation details from high-level page allocator comments, and eliminates obsolete VM_BUG_ON() assertions in allocation paths. - "mm/mseal: further cleanups" (Lorenzo Stoakes) Refactor and simplify the mseal implementation by clarifying API boundaries and removing unnecessary code complexity. It replaces generic do_mseal() usage outside the syscall with a dedicated mseal_mmap_page_zero() helper for MMAP_PAGE_ZERO, eliminates mm_struct parameters to enforce that sealing applies only to current->mm, and streamlines overall logic and comments with no functional changes intended. - "mm/vmscan: fix swappiness=max and clean up per-node proactive reclaim" (Ridong Chen) Resolve reclaim behavior bugs and clean up function parameters across memory reclaim paths It fixes swappiness=max in both standard reclaim and MGLRU so unswappable anonymous memory no longer falls back to evicting page cache, ensures reclaim_store() returns accurate error codes instead of collapsing all failures into -EAGAIN, and removes the obsolete gfp_mask parameter from __node_reclaim(). - "mm: mincore: misc cleanups" (Kefeng Wang) Clean up and simplifies the mincore code. Most importantly, it removes the historical special behavior that always reports VM_PFNMAP pages as non-resident. - "mm/huge_memory: drop dead split helper variants" (Kiryl Shutsemau) Two trivial cleanups in the folio split API - "mm/damon: fix uninitialized DAMOS field and kunit exec expectation bugs" (SJ Park) Resolve minor operational and testing bugs in DAMON identified by Sashiko. It initializes the damos->last_applied field to prevent occasional efficiency degradation and fixes invalid memory accesses in DAMON KUnit tests during test failure handling. - "cleanup for stable_page_flags()" (Jinjiang Tu) Clean up and refactor stable_page_flags() used by /proc/kpageflags without altering functionality. It uses BIT_ULL() to prevent shift-overflow warnings on 64-bit flag bits, converts folio-specific flag checks to standard folio_test_*() helpers, and removes redundant CONFIG_PAGE_IDLE_FLAG handling. - "Batch unmap of uffd-wp file folios" (Dev Jain) Extend batched folio unmapping support to file folios within userfaultfd write-protect (uffd-wp) VMAs by adding batching capabilities to pte_install_uffd_wp_if_needed(). This removes special-case restrictions on uffd-wp VMAs in try_to_unmap_one(), significantly simplifying the function's control flow and complexity. - "mm/early_ioremap: clarify and clean up early_ioremap_reset()" (Sang-Heon Jeon) Clarify and clean up the architecture-specific usage of __late_set_fixmap() and __late_clear_fixmap() after early_ioremap_reset() It adds explicit documentation regarding when early_ioremap_reset() must be called and removes redundant macro definitions and reset calls in the RISC-V and ARM64 architectures. - "mm: fix reclaim storms in defrag_mode" (Johannes Weiner) Address severe performance regressions, swap storms, and spurious OOMs caused by vm.defrag_mode=1 under high memory pressure in Meta production It updates the page allocator slowpath so non-movable allocation requests actively trigger direct reclaim and direct compaction at pageblock_order scale, allowing them to claim whole pageblocks rather than spinning unproductively. - "zram: lockmap tweaks" (Sebastian Siewior) Optimize and fix lockdep tracking for zram devices by consolidating per-entry lockmaps and isolate lock classes across multiple instances This reduces memory overhead by replacing per-entry lockdep_map instances with a single map per struct zram, and assigns a dynamic lock_class_key to each instance to prevent false deadlock reports when different zram devices are backed by distinct filesystems.* tag 'mm-stable-2026-08-18-18-39' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (501 commits) selftests/mm: thuge-gen: fix test_shmget() for PAGE_SIZE check selftests/mm: unpoison pages in memory-failure teardown mm/shmem: downgrade final i_blocks check in shmem_evict_inode() to pr_warn() mm/khugepaged: replace mutex_lock/mutex_unlock usage with guard macro mm/zsmalloc: fix release order of locks in zs_page_migrate() Documentation: zram: remove sections numbering ksm: stop iterating VMAs when ksm_test_exit returns true mm: fold userfaultfd_rwp() to false without CONFIG_ARCH_HAS_PTE_PROTNONE mm/migrate: report RCU-tasks quiescent states in migrate_pages_batch() zram: use a custom key for each zram object zram: move lockmap to be per-zram instead per table selftests/mm: fix gup_longterm EINVAL error message mm: page_alloc: fix non-movable reclaim storm in defrag_mode mm: page_alloc: move capture_control to the page allocator mm: compaction: support non-movable compaction for pageblock requests mm: page_alloc: __GFP_FS lockdep annotation for direct compaction hugetlb: evaluate subpool free state while locked mm/damon: remove trailing semicolons after function definitions mm/damon/ops-common: prevent migration fallback to non-target nodes mm/damon: update outdated comment about DAMOS filter handling ...

This capability is useful beyond NUMA balancing -- forexample, userfaultfd working set tracking uses protnone PTEs to track pageaccess without unmapping pages.Introduce CONFIG_ARCH_HAS_PTE_PROTNONE to decouple the protnone PTEinfrastructure from CONFIG_NUMA_BALANCING. The six architectures thatsupport protnone PTEs (x86_64, arm64, powerpc, s390, riscv, loongarch) nowselect this option, and CONFIG_NUMA_BALANCING depends on it.No functional change -- the same set of architectures continues to haveworking protnone support, but the infrastructure is now availableindependently of NUMA balancing.Link: https://lore.kernel.org/20260708111417.173443-1-kirill@shutemov.nameLink: https://lore.kernel.org/20260708111417.173443-2-kirill@shutemov.nameSigned-off-by: Kiryl Shutsemau (Meta) <kas@kernel.org>Assisted-by: Claude:claude-opus-4-6Acked-by: SeongJae Park <sj@kernel.org>Acked-by: Mike Rapoport (Microsoft) <rppt@kernel.org>Cc: Andrea Arcangeli <aarcange@redhat.com>Cc: David Hildenbrand <david@kernel.org>Cc: James Houghton <jthoughton@google.com>Cc: Jonathan Corbet <corbet@lwn.net>Cc: Liam Howlett <liam@infradead.org>Cc: Lorenzo Stoakes <ljs@kernel.org>Cc: Paolo Bonzini <pbonzini@redhat.com>Cc: Peter Xu <peterx@redhat.com>Cc: Sean Christopherson <seanjc@google.com>Cc: Suren Baghdasaryan <surenb@google.com>Cc: Vlastimil Babka <vbabka@kernel.org>Cc: Zi Yan <ziy@nvidia.com>Signed-off-by: Andrew Morton <akpm@linux-foundation.org> List of files: /linux/arch/riscv/Kconfig Wed, 08 Jul 2026 13:14:02 +0200 Kiryl Shutsemau (Meta) <kas@kernel.org> http://kernelsources.org:8080/source/history/linux/arch/riscv/Kconfig#d547b1001755c170094c64bc45f9efba2c150feb mm: rename ARCH_ENABLE_THP_MIGRATION to ARCH_HAS_PMD_SOFTLEAVESCONFIG_ARCH_ENABLE_THP_MIGRATION gates PMD-level migration entries. PMD-level device-private entries use the same migration mechanism andtherefore require the same architecture support.Upcoming PMD-level swap entries can use the same PMD softleaf helperswithout depending on page migration, so rename the architecture gate toCONFIG_ARCH_HAS_PMD_SOFTLEAVES. This describes the PMD entry capabilityrather than one current user of it.This is a pure rename: the set of selecting architectures (x86, arm64,s390, riscv, loongarch, and powerpc on PPC_BOOK3S_64) and the gatingsemantics are unchanged.No functional change intended.Link: https://lore.kernel.org/20260706114320.1643046-7-usama.arif@linux.devSigned-off-by: Usama Arif <usama.arif@linux.dev>Reviewed-by: Zi Yan <ziy@nvidia.com>Acked-by: David Hildenbrand (Arm) <david@kernel.org>Cc: Alexandre Ghiti <alex@ghiti.fr>Cc: Baolin Wang <baolin.wang@linux.alibaba.com>Cc: Baoquan He <baoquan.he@linux.dev>Cc: Barry Song <baohua@kernel.org>Cc: Chris Li <chrisl@kernel.org>Cc: Dev Jain <dev.jain@arm.com>Cc: "Huang, Ying" <ying.huang@linux.alibaba.com>Cc: Johannes Weiner <hannes@cmpxchg.org>Cc: Kairui Song <kasong@tencent.com>Cc: Kemeng Shi <shikemeng@huaweicloud.com>Cc: Kiryl Shutsemau <kas@kernel.org>Cc: Lance Yang <lance.yang@linux.dev>Cc: Liam R.
