This leads to improved memory savings. - Wei Yang has gone to town on the mapletree code, contributing several series which clean up the implementation: - "refine mas_mab_cp()" - "Reduce the space to be cleared for maple_big_node" - "maple_tree: simplify mas_push_node()" - "Following cleanup after introduce mas_wr_store_type()" - "refine storing null" - The series "selftests/mm: hugetlb_fault_after_madv improvements" from David Hildenbrand fixes this selftest for s390. - The series "introduce pte_offset_map_{ro|rw}_nolock()" from Qi Zheng implements some rationaizations and cleanups in the page mapping code. - The series "mm: optimize shadow entries removal" from Shakeel Butt optimizes the file truncation code by speeding up the handling of shadow entries. - The series "Remove PageKsm()" from Matthew Wilcox completes the migration of this flag over to being a folio-based flag. - The series "Unify hugetlb into arch_get_unmapped_area functions" from Oscar Salvador implements a bunch of consolidations and cleanups in the hugetlb code. - The series "Do not shatter hugezeropage on wp-fault" from Dev Jain takes away the wp-fault time practice of turning a huge zero page into small pages. Instead we replace the whole thing with a THP. More consistent cleaner and potentiall saves a large number of pagefaults. - The series "percpu: Add a test case and fix for clang" from Andy Shevchenko enhances and fixes the kernel's built in percpu test code. - The series "mm/mremap: Remove extra vma tree walk" from Liam Howlett optimizes mremap() by avoiding doing things which we didn't need to do. - The series "Improve the tmpfs large folio read performance" from Baolin Wang teaches tmpfs to copy data into userspace at the folio size rather than as individual pages. A 20% speedup was observed. - The series "mm/damon/vaddr: Fix issue in damon_va_evenly_split_region()" fro Zheng Yejian fixes DAMON splitting. - The series "memcg-v1: fully deprecate charge moving" from Shakeel Butt removes the long-deprecated memcgv2 charge moving feature. - The series "fix error handling in mmap_region() and refactor" from Lorenzo Stoakes cleanup up some of the mmap() error handling and addresses some potential performance issues. - The series "x86/module: use large ROX pages for text allocations" from Mike Rapoport teaches x86 to use large pages for read-only-execute module text. - The series "page allocation tag compression" from Suren Baghdasaryan is followon maintenance work for the new page allocation profiling feature. - The series "page->index removals in mm" from Matthew Wilcox remove most references to page->index in mm/. A slow march towards shrinking struct page. - The series "damon/{self,kunit}tests: minor fixups for DAMON debugfs interface tests" from Andrew Paniakin performs maintenance work for DAMON's self testing code. - The series "mm: zswap swap-out of large folios" from Kanchana Sridhar improves zswap's batching of compression and decompression. It is a step along the way towards using Intel IAA hardware acceleration for this zswap operation. - The series "kasan: migrate the last module test to kunit" from Sabyrzhan Tasbolatov completes the migration of the KASAN built-in tests over to the KUnit framework. - The series "implement lightweight guard pages" from Lorenzo Stoakes permits userapace to place fault-generating guard pages within a single VMA, rather than requiring that multiple VMAs be created for this. Improved efficiencies for userspace memory allocators are expected. - The series "memcg: tracepoint for flushing stats" from JP Kobryn uses tracepoints to provide increased visibility into memcg stats flushing activity. - The series "zram: IDLE flag handling fixes" from Sergey Senozhatsky fixes a zram buglet which potentially affected performance. - The series "mm: add more kernel parameters to control mTHP" from Maíra Canal enhances our ability to control/configuremultisize THP from the kernel boot command line. - The series "kasan: few improvements on kunit tests" from Sabyrzhan Tasbolatov has a couple of fixups for the KASAN KUnit tests. - The series "mm/list_lru: Split list_lru lock into per-cgroup scope" from Kairui Song optimizes list_lru memory utilization when lockdep is enabled. ---------------------------------------------------------------- Adrian Huang (1): mm/vmalloc: combine all TLB flush operations of KASAN shadow virtual address into one operation Alexey Klimov (1): MAINTAINERS: mailmap: update Alexey Klimov's email address Andrew Morton (3): Merge branch 'mm-hotfixes-stable' into mm-stable. mm/memory.c: remove stray newline at top of file Merge branch 'mm-hotfixes-stable' into mm-stable Andrew Paniakin (1): selftests/damon/huge_count_read_write: provide sufficiently large buffer for DEPRECATED file read Andy Shevchenko (2): x86/percpu: fix clang warning when dealing with unsigned types percpu: add a test case for the specific 64-bit value addition Anshuman Khandual (1): mm: move set_pxd_safe() helpers from generic to platform Ba Jing (1): selftests/damon/access_memory_even: remove unused variables Baolin Wang (4): mm: shmem: fix khugepaged activation policy for shmem mm: shmem: update iocb->ki_pos directly to simplify tmpfs read logic mm: shmem: improve the tmpfs large folio read performance mm: shmem: fallback to page size splice if large folio has poisoned pages Barry Song (1): mm: add per-order mTHP swpin counters Bibo Mao (1): mm: define general function pXd_init() Breno Leitao (1): mm: remove misleading 'unlikely' hint in vms_gather_munmap_vmas() Catalin Marinas (1): kmemleak: iommu/iova: fix transient kmemleak false positive Chunyan Zhang (2): selftest/mm: fix typo in virtual_address_range selftests/mm: skip virtual_address_range tests on riscv David Hildenbrand (2): selftests/mm: hugetlb_fault_after_madv: use default hugetlb page size selftests/mm: hugetlb_fault_after_madv: improve test output Dennis Zhou (1): percpu: fix data race with pcpu_nr_empty_pop_pages Dev Jain (3): mm: abstract THP allocation mm: allocate THP on hugezeropage wp-fault mm: remove redundant condition for THP folio Geert Uytterhoeven (1): zram: ZRAM_DEF_COMP should depend on ZRAM Hugh Dickins (1): mm: delete the unused put_pages_list() JP Kobryn (2): memcg: rename do_flush_stats and add force flag memcg: add flush tracepoint Jaewon Kim (1): vmscan: add a vmscan event for reclaim_pages James Houghton (1): mm: add missing mmu_notifier_clear_young for !MMU_NOTIFIER Jann Horn (1): maple_tree: fix outdated flag name in comment Jiazi Li (2): maple_tree: fix alloc node fail issue maple_tree: add some alloc node test case Jim Zhao (1): mm/page-writeback: raise wb_thresh to prevent write blocking with strictlimit Jingxiang Zeng (1): mm/memcontrol: add per-memcg pgpgin/pswpin counter John Hubbard (1): kaslr: rename physmem_end and PHYSMEM_END to direct_map_physmem_end Joshua Hahn (1): memcg/hugetlb: add hugeTLB counters to memcg Kairui Song (7): mm/zswap: avoid touching XArray for unnecessary invalidation mm/list_lru: don't pass unnecessary key parameters mm/list_lru: don't export list_lru_add mm/list_lru: code clean up for reparenting mm/list_lru: simplify reparenting and initial allocation mm/list_lru: split the lock to per-cgroup scope mm/list_lru: simplify the list_lru walk callback function Kanchana P Sridhar (8): mm: swap: make some count_mthp_stat() call-sites be THP-agnostic. mm: define obj_cgroup_get() if CONFIG_MEMCG is not defined mm: zswap: modify zswap_compress() to accept a page instead of a folio mm: zswap: rename zswap_pool_get() to zswap_pool_tryget() mm: zswap: modify zswap_stored_pages to be atomic_long_t mm: zswap: support large folios in zswap_store() mm: swap: count successful large folio zswap stores in hugepage zswpout stats mm: zswap: zswap_store_page() will initialize entry after adding to xarray.
