07e23d0b6f58eec351e52058b9a0a8af7b019c09 - riscv: fix NR_CPUS range leaking 64-bit default onto 32-bit builds

Wed, 07 Oct 2026 06:52:29 +0200

riscv: fix NR_CPUS range leaking 64-bit default onto 32-bit buildsrv32_defconfig is built in two stages:- the generic (64-bit-oriented) "defconfig" target runs first and resolves a concrete NR_CPUS value using the 64BIT default.- then 32-bit.config is merged on top via merge_config.sh, which does not touch NR_CPUS.The final "make olddefconfig" pass sees NR_CPUS=256 is still withinthe "2 512" range therefore never recalculates it against the 32BITdefault of 32, silently keeping the leaked 64-bit-stage value.The NR_CPUS-scaled regions (percpu areas, ...etc) of the resultingCONFIG_NR_CPUS=256 on a 32-bit build bloats and does not fit in thepercpu/stack layout for rv32 and hangs early boot on QEMU's virt machine.Fix this by explicitly specify the range for 32/64 and SBI_V01/!SBI_V01.Fixes: 0fa749771993 ("riscv: Raise default NR_CPUS for 64BIT to 256")Signed-off-by: Leo Yu-Chi Liang Link: https://patch.msgid.link/20261007045229.36114-1-leo.liang@sifive.comSigned-off-by: Paul Walmsley List of files: /linux/arch/riscv/Kconfig

"mm/damon: refactor damon_{start,stop,commit}() for simple error handling" (SJ Park) Refactor the DAMON core API functions to guarantee that all contexts are fully stopped when damon_start(), damon_stop(), or damon_commit() fail, eliminating the need for complex and error-prone caller-side cleanup code - "Keep tail page private zero at free and folio split" (Zi Yan) Add checks to ensure tail_page->private is zero when freeing compound or high-order pages and when promoting tail pages during large folio splits. By validating these fields at free and split time, it allows the removal of redundant private field clearing inside prep_compound_tail() - "mm: drop redundant lru_add_drain in anon folio reuse paths" (Barry Song) Eliminate redundant lru_add_drain() calls in wp_can_reuse_anon_folio() and do_swap_page() to reduce LRU lock contention and system overhead By validating folio refcounts against the LRU cache before draining and removing unnecessary drains in the swap path, it achieves up to a 30.5% reduction in drain calls during heavy swap workloads - "mm: clean up folio LRU and swap declarations" (Jianyue Wu) Reorganize folio LRU and swap code by relocating page-cluster state to mm/swap_state.c, renaming mm/swap.c to mm/folio.c, and moving MM-internal reclaim declarations into mm/internal.h. - "userfaultfd: working set tracking for VM guest memory" (Kiryl Shutsemau) Add userfaultfd support for tracking the working set of VM guest memory, so a VMM can identify hot pages and reclaim cold ones to tiered or remote storage - "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 2)" (David Hildenbrand) Remove the remaining pieces of CONFIG_HAVE_BOOTMEM_INFO_NODE, performing some smaller cleanups around freeing of reserved vmemmap pages on the way. - "mm/damon: update probe hits for runtime parameter commits" (SJ Park) Ensure that DAMON's probe_hits attribute counter is properly updated when monitoring intervals are changed at runtime, matching the behavior of nr_accesses. To achieve this, it refactors and renames existing helper functions for shared use, applies the updates to probe_hits, and handles edge cases in damon_probe_hits_mvsum() to maintain measurement accuracy. - "KSM: performance optimizations for rmap_walk_ksm" (xu xin) Resolve a severe KSM reverse-mapping performance bottleneck where thousands of split VMAs sharing a single anon_vma cause extended lock contention. By adding an interval-filtering check during the rmap walk, it reduces worst-case anon_vma lock hold times from over 500ms down to under 2ms, preventing application freezes and latency spikes under memory pressure. - "mm: split a couple of headers from internal.h" (Mike Rapoport) Split declarations related to mm_init, memblock, vmalloc and sparse into new headers - "KSM: use linear_page_index in collect_procs_ksm()" (xu xin) Apply the interval tree optimization from rmap_walk_ksm() to collect_procs_ksm() to avoid iterating over non-matching VMAs during KSM memory error handling. It hoists loop-invariant address initialization and restricts the anon_vma_interval_tree_foreach walk to a targeted page offset range, reducing redundant checks and improving lookup efficiency. - "selftests/mm: avoid false failures in hugetlb and KSM tests" (Sayali Patil) Fix issues in the hugetlb and KSM MM selftest categories that can report failures when the prerequisites for the tests are not satisfied - "mm/damon: introduce data attributes only monitoring" (SJ Park) Introduce attribute-weighted region management in DAMON, allowing users to prioritize specific data attributes (such as page sizes or cgroups) over or instead of access monitoring. By assigning weights to attribute probes, DAMON can completely disable access tracking and adjust monitoring regions based on weighted probe-hit counters to optimize monitoring quality for attribute-focused workloads. - "mm/hmm: Add mmap lock-drop support for userfaultfd-backed mappings" (Stanislav Kinsburskii) Extend hmm_range_fault() to support userfaultfd-backed regions by allowing the mmap lock to be dropped during fault handling via a new hmm_range_fault_locked() helper. By accepting a locked pointer and signaling retry status when lock release occurs, it enables page fault resolution in userfaultfd regions while preserving backward compatibility for existing callers. - "mm: make VMA page offset handling more consistent" (Lorenzo Stoakes) Clean up and standardize how vma->vm_pgoff is accessed and manipulated across file-backed and anonymous mappings in the kernel It introduces dedicated helper functions such as vma_start_pgoff(), vma_end_pgoff(), vma_set_pgoff() and linear_page_delta() while renaming rmap interval tree helpers to better reflect their functionality. 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 ...

riscv: Add support for srmcfg CSR from Ssqosid extensionAdd support for the srmcfg CSR defined in the Ssqosid ISA extension.The CSR contains two fields: - Resource Control ID (RCID) for resource allocation - Monitoring Counter ID (MCID) for tracking resource usageRequests from a hart to shared resources are tagged with these IDs,allowing resource usage to be associated with the running task.Add a srmcfg field to thread_struct with the same format as the CSR.The context-switch path writes the field to the CSR, andresctrl_arch_set_closid_rmid() updates it when a task is assigned to aresctrl control or monitoring group.A per-cpu cpu_srmcfg_default holds the default srmcfg for each CPU, setby resctrl_arch_set_cpu_default_closid_rmid() on CPU group assignment.On context switch, RCID and MCID inherit from the CPU defaultindependently: a task whose thread RCID field is zero takes the CPUdefault's RCID, and likewise for MCID.A per-cpu cpu_srmcfg variable mirrors the CSR state to avoidredundant writes. L1D-hot memory access is faster than a CSR read andavoids traps under virtualization.Link: https://github.com/riscv/riscv-ssqosid/releases/tag/v1.0Assisted-by: Claude:claude-opus-4-7Co-developed-by: Kornel Dulęba Signed-off-by: Kornel Dulęba Signed-off-by: Drew Fustini Link: https://patch.msgid.link/20260729-dfustini-atl-sc-cbqri-dt-v6-3-7c22b05d461b@kernel.orgSigned-off-by: Paul Walmsley List of files: /linux/arch/riscv/Kconfig

Wed, 08 Jul 2026 13:14:02 +0200

mm: decouple protnone helpers from CONFIG_NUMA_BALANCINGPatch series "userfaultfd: working set tracking for VM guest memory", v10.This series adds userfaultfd support for tracking the working set of VMguest memory, so a VMM can identify hot pages and reclaim cold ones totiered or remote storage.This patch (of 15):pte_protnone() and pmd_protnone() detect present-but-inaccessible pagetable entries. 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) Assisted-by: Claude:claude-opus-4-6Acked-by: SeongJae Park Acked-by: Mike Rapoport (Microsoft) Cc: Andrea Arcangeli Cc: David Hildenbrand Cc: James Houghton Cc: Jonathan Corbet Cc: Liam Howlett Cc: Lorenzo Stoakes Cc: Paolo Bonzini Cc: Peter Xu Cc: Sean Christopherson Cc: Suren Baghdasaryan Cc: Vlastimil Babka Cc: Zi Yan Signed-off-by: Andrew Morton List of files: /linux/arch/riscv/Kconfig

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 Reviewed-by: Zi Yan Acked-by: David Hildenbrand (Arm) Cc: Alexandre Ghiti Cc: Baolin Wang Cc: Baoquan He Cc: Barry Song Cc: Chris Li Cc: Dev Jain Cc: "Huang, Ying" Cc: Johannes Weiner Cc: Kairui Song Cc: Kemeng Shi Cc: Kiryl Shutsemau Cc: Lance Yang Cc: Liam R.

Mon, 06 Jul 2026 15:04:14 +0200

riscv: Gate FUNCTION_ALIGNMENT_4B on DYNAMIC_FTRACEThe FUNCTION_ALIGNMENT_4B select forces the whole kernel to be builtwith -fmin-function-alignment=4. This alignment is only needed so thepatchable-function-entry NOPs, which arch/riscv/Makefile emits underCONFIG_DYNAMIC_FTRACE, can be patched reliably on RISCV_ISA_C=y buildswhere compressed instructions otherwise allow 2-byte functionalignment.The select is currently gated on HAVE_DYNAMIC_FTRACE, a capability bitthat is selected whenever the toolchain supports dynamic ftrace, ratherthan on whether tracing is actually enabled. As a result everyRISCV_ISA_C=y build gets 4-byte function alignment across the entirekernel even when function tracing is disabled, needlessly growing thekernel image and wasting instruction cache for a feature that is notin use.Gate the select on DYNAMIC_FTRACE instead, matching the condition underwhich arch/riscv/Makefile emits -fpatchable-function-entry, so thealignment is only applied when it is actually needed.Fixes: c41bf4326c7b ("riscv: ftrace: align patchable functions to 4 Byte boundary")Signed-off-by: Rui Qi Link: https://patch.msgid.link/20260706130415.463682-1-qirui.001@bytedance.comSigned-off-by: Paul Walmsley List of files: /linux/arch/riscv/Kconfig

riscv: Raise default NR_CPUS for 64BIT to 256SpacemiT has already produced a 80-core RVA23 RISC-V server [1], andgoing further back, the dual-socket SG2042-based Sophgo Pisces has 128cores (although that had some issues achieving mainline support).Therefore, an NR_CPUS of 64 is not enough.Raise default NR_CPUS to 256 for 64BIT (when !RISCV_SBI_V01, since veryold firmware can't support more than 64 cores). The number was picked asa power of two that is at least double the known max. I believe thisshould be the right balance between not wasting too much memory and nothaving to touch this too often.Ubuntu has already been shipping NR_CPUS=512 for riscv64. We have alsobeen testing NR_CPUS=256 internally at ISCAS and found negligibleperformance impact and no ill effects.Reported-by: Lufei Zheng Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1140651 # [1]Suggested-by: Han Gao Signed-off-by: Vivian Wang Link: https://patch.msgid.link/20260625-riscv-more-nr-cpus-v1-1-5da8c72b9269@iscas.ac.cnSigned-off-by: Paul Walmsley List of files: /linux/arch/riscv/Kconfig
