It # also speeds up GUP handling of transparent hugepages. # # - Peng Zhang provides some maple tree speedups ("Optimize the fast path # of mas_store()"). # # - Sergey Senozhatsky has improved te performance of zsmalloc during # compaction (zsmalloc: small compaction improvements"). # # - Domenico Cerasuolo has developed additional selftest code for zswap # ("selftests: cgroup: add zswap test program"). # # - xu xin has doe some work on KSM's handling of zero pages. These # changes are mainly to enable the user to better understand the # effectiveness of KSM's treatment of zero pages ("ksm: support # tracking KSM-placed zero-pages"). # # - Jeff Xu has fixes the behaviour of memfd's # MEMFD_NOEXEC_SCOPE_NOEXEC_ENFORCED sysctl ("mm/memfd: fix sysctl # MEMFD_NOEXEC_SCOPE_NOEXEC_ENFORCED"). # # - David Howells has fixed an fscache optimization ("mm, netfs, fscache: # Stop read optimisation when folio removed from pagecache"). # # - Axel Rasmussen has given userfaultfd the ability to simulate memory # poisoning ("add UFFDIO_POISON to simulate memory poisoning with # UFFD"). # # - Miaohe Lin has contributed some routine maintenance work on the # memory-failure code ("mm: memory-failure: remove unneeded PageHuge() # check"). # # - Peng Zhang has contributed some maintenance work on the maple tree # code ("Improve the validation for maple tree and some cleanup"). # # - Hugh Dickins has optimized the collapsing of shmem or file pages into # THPs ("mm: free retracted page table by RCU"). # # - Jiaqi Yan has a patch series which permits us to use the healthy # subpages within a hardware poisoned huge page for general purposes # ("Improve hugetlbfs read on HWPOISON hugepages"). # # - Kemeng Shi has done some maintenance work on the pagetable-check code # ("Remove unused parameters in page_table_check"). # # - More folioification work from Matthew Wilcox ("More filesystem folio # conversions for 6.6"), ("Followup folio conversions for zswap"). And # from ZhangPeng ("Convert several functions in page_io.c to use a # folio"). # # - page_ext cleanups from Kemeng Shi ("minor cleanups for page_ext"). # # - Baoquan He has converted some architectures to use the # GENERIC_IOREMAP ioremap()/iounmap() code ("mm: ioremap: Convert # architectures to take GENERIC_IOREMAP way"). # # - Anshuman Khandual has optimized arm64 tlb shootdown ("arm64: support # batched/deferred tlb shootdown during page reclamation/migration"). # # - Better maple tree lockdep checking from Liam Howlett ("More strict # maple tree lockdep"). Liam also developed some efficiency # improvements ("Reduce preallocations for maple tree"). # # - Cleanup and optimization to the secondary IOMMU TLB invalidation, # from Alistair Popple ("Invalidate secondary IOMMU TLB on permission # upgrade"). # # - Ryan Roberts fixes some arm64 MM selftest issues ("selftests/mm fixes # for arm64"). # # - Kemeng Shi provides some maintenance work on the compaction code # ("Two minor cleanups for compaction"). # # - Some reduction in mmap_lock pressure from Matthew Wilcox ("Handle # most file-backed faults under the VMA lock"). # # - Aneesh Kumar contributes code to use the vmemmap optimization for DAX # on ppc64, under some circumstances ("Add support for DAX vmemmap # optimization for ppc64"). # # - page-ext cleanups from Kemeng Shi ("add page_ext_data to get client # data in page_ext"), ("minor cleanups to page_ext header"). # # - Some zswap cleanups from Johannes Weiner ("mm: zswap: three # cleanups"). # # - kmsan cleanups from ZhangPeng ("minor cleanups for kmsan"). # # - VMA handling cleanups from Kefeng Wang ("mm: convert to # vma_is_initial_heap/stack()"). # # - DAMON feature work from SeongJae Park ("mm/damon/sysfs-schemes: # implement DAMOS tried total bytes file"), ("Extend DAMOS filters for # address ranges and DAMON monitoring targets"). # # - Compaction work from Kemeng Shi ("Fixes and cleanups to compaction"). # # - Liam Howlett has improved the maple tree node replacement code # ("maple_tree: Change replacement strategy"). # # - ZhangPeng has a general code cleanup - use the K() macro more widely # ("cleanup with helper macro K()"). # # - Aneesh Kumar brings memmap-on-memory to ppc64 ("Add support for # memmap on memory feature on ppc64"). # # - pagealloc cleanups from Kemeng Shi ("Two minor cleanups for pcp list # in page_alloc"), ("Two minor cleanups for get pageblock # migratetype"). # # - Vishal Moola introduces a memory descriptor for page table tracking, # "struct ptdesc" ("Split ptdesc from struct page"). # # - memfd selftest maintenance work from Aleksa Sarai ("memfd: cleanups # for vm.memfd_noexec"). # # - MM include file rationalization from Hugh Dickins ("arch: include # asm/cacheflush.h in asm/hugetlb.h"). # # - THP debug output fixes from Hugh Dickins ("mm,thp: fix sloppy text # output"). # # - kmemleak improvements from Xiaolei Wang ("mm/kmemleak: use # object_cache instead of kmemleak_initialized"). # # - More folio-related cleanups from Matthew Wilcox ("Remove _folio_dtor # and _folio_order"). # # - A VMA locking scalability improvement from Suren Baghdasaryan # ("Per-VMA lock support for swap and userfaults"). # # - pagetable handling cleanups from Matthew Wilcox ("New page table # range API"). # # - A batch of swap/thp cleanups from David Hildenbrand ("mm/swap: stop # using page->private on tail pages for THP_SWAP + cleanups"). # # - Cleanups and speedups to the hugetlb fault handling from Matthew # Wilcox ("Change calling convention for ->huge_fault"). # # - Matthew Wilcox has also done some maintenance work on the MM # subsystem documentation ("Improve mm documentation"). # # * tag 'mm-stable-2023-08-28-18-26' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (489 commits) # maple_tree: shrink struct maple_tree # maple_tree: clean up mas_wr_append() # secretmem: convert page_is_secretmem() to folio_is_secretmem() # nios2: fix flush_dcache_page() for usage from irq context # hugetlb: add documentation for vma_kernel_pagesize() # mm: add orphaned kernel-doc to the rst files. # mm: fix clean_record_shared_mapping_range kernel-doc # mm: fix get_mctgt_type() kernel-doc # mm: fix kernel-doc warning from tlb_flush_rmaps() # mm: remove enum page_entry_size # mm: allow ->huge_fault() to be called without the mmap_lock held # mm: move PMD_ORDER to pgtable.h # mm: remove checks for pte_index # memcg: remove duplication detection for mem_cgroup_uncharge_swap # mm/huge_memory: work on folio->swap instead of page->private when splitting folio # mm/swap: inline folio_set_swap_entry() and folio_swap_entry() # mm/swap: use dedicated entry for swap in folio # mm/swap: stop using page->private on tail pages for THP_SWAP # selftests/mm: fix WARNING comparing pointer to 0 # selftests: cgroup: fix test_kmem_memcg_deletion kernel mem check # ... # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux-ld --version # < git log --format=%s --max-count=1 b96a3e9142fdf346b05b20e867b4f0dfca119e96 # make -s -j 160 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MIPS_CPS_NS16550_BASE=0x1b0003f8 # Added to kconfig CONFIG_MIPS_CPS_NS16550_SHIFT=0 # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig # < make -s -j 160 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- help # make -s -j 160 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- olddefconfig .config:14529:warning: override: reassigning to symbol MIPS_CPS_NS16550_SHIFT # make -s -j 160 ARCH=mips O=/kisskb/build/linus-rand_allmodconfig_mips-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/mips-linux/bin/mips-linux- Completed OK # rm -rf /kisskb/build/linus-rand_allmodconfig_mips-gcc13 # Build took: 0:09:48.980108
