Pull MM updates from Andrew Morton: - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam Howlett. An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1]. This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths. For optimizations by PMEM drivers, DRM drivers, etc. - vma merging improvements from Jakub Matěn. - NUMA hinting cleanups from David Hildenbrand. - xu xin added aditional userspace visibility into KSM merging activity. - THP & KSM code consolidation from Qi Zheng. - more folio work from Matthew Wilcox. - KASAN updates from Andrey Konovalov. - DAMON cleanups from Kaixu Xia. - DAMON work from SeongJae Park: fixes, cleanups. - hugetlb sysfs cleanups from Muchun Song. - Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core.

Pull x86 mm updates from Dave Hansen: "There are some small things here, plus one big one. The big one detected and refused to create W+X kernel mappings. This caused a bit of trouble and it is entirely disabled on 32-bit due to known unfixable EFI issues. It also oopsed on some systemd eBPF use, which kept some users from booting. The eBPF issue is fixed, but those troubles were caught relatively recently which made me nervous that there are more lurking. The final commit in here retains the warnings, but doesn't actually refuse to create W+X mappings. Summary: - Detect insecure W+X mappings and warn about them, including a few bug fixes and relaxing the enforcement - Do a long-overdue defconfig update and enabling W+X boot-time detection - Cleanup _PAGE_PSE handling (follow-up on an earlier bug) - Rename a change_page_attr function" * tag 'x86_mm_for_v6.1_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm: Ease W^X enforcement back to just a warning x86/mm: Disable W^X detection and enforcement on 32-bit x86/mm: Add prot_sethuge() helper to abstract out _PAGE_PSE handling x86/mm/32: Fix W^X detection when page tables do not support NX x86/defconfig: Enable CONFIG_DEBUG_WX=y x86/defconfig: Refresh the defconfigs x86/mm: Refuse W^X violations x86/mm: Rename set_memory_present() to set_memory_p()

Pull random number generator updates from Jason Donenfeld: - Huawei reported that when they updated their kernel from 4.4 to something much newer, some userspace code they had broke, the culprit being the accidental removal of O_NONBLOCK from /dev/random way back in 5.6. It's been gone for over 2 years now and this is the first we've heard of it, but userspace breakage is userspace breakage, so O_NONBLOCK is now back. - Use randomness from hardware RNGs much more often during early boot, at the same interval that crng reseeds are done, from Dominik. - A semantic change in hardware RNG throttling, so that the hwrng framework can properly feed random.c with randomness from hardware RNGs that aren't specifically marked as creditable. A related patch coming to you via Herbert's hwrng tree depends on this one, not to compile, but just to function properly, so you may want to merge this PULL before that one. - A fix to clamp credited bits from the interrupts pool to the size of the pool sample. This is mainly just a theoretical fix, as it'd be pretty hard to exceed it in practice. - Oracle reported that InfiniBand TCP latency regressed by around 10-15% after a change a few cycles ago made at the request of the RT folks, in which we hoisted a somewhat rare operation (1 in 1024 times) out of the hard IRQ handler and into a workqueue, a pretty common and boring pattern. It turns out, though, that scheduling a worker from there has overhead of its own, whereas scheduling a timer on that same CPU for the next jiffy amortizes better and doesn't incur the same overhead. I also eliminated a cache miss by moving the work_struct (and subsequently, the timer_list) to below a critical cache line, so that the more critical members that are accessed on every hard IRQ aren't split between two cache lines. - The boot-time initialization of the RNG has been split into two approximate phases: what we can accomplish before timekeeping is possible and what we can accomplish after. This winds up being useful so that we can use RDRAND to seed the RNG before CONFIG_SLAB_FREELIST_RANDOM=y systems initialize slabs, in addition to other early uses of randomness. The effect is that systems with RDRAND (or a bootloader seed) will never see any warnings at all when setting CONFIG_WARN_ALL_UNSEEDED_RANDOM=y. And kfence benefits from getting a better seed of its own. - Small systems without much entropy sometimes wind up putting some truncated serial number read from flash into hostname, so contribute utsname changes to the RNG, without crediting. - Add smaller batches to serve requests for smaller integers, and make use of them when people ask for random numbers bounded by a given compile-time constant. This has positive effects all over the tree, most notably in networking and kfence. - The original jitter algorithm intended (I believe) to schedule the timer for the next jiffy, not the next-next jiffy, yet it used mod_timer(jiffies + 1), which will fire on the next-next jiffy, instead of what I believe was intended, mod_timer(jiffies), which will fire on the next jiffy. So fix that. - Fix a comment typo, from William. * tag 'random-6.1-rc1-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random: random: clear new batches when bringing new CPUs online random: fix typos in get_random_bytes() comment random: schedule jitter credit for next jiffy, not in two jiffies prandom: make use of smaller types in prandom_u32_max random: add 8-bit and 16-bit batches utsname: contribute changes to RNG random: use init_utsname() instead of utsname() kfence: use better stack hash seed random: split initialization into early step and later step random: use expired timer rather than wq for mixing fast pool random: avoid reading two cache lines on irq randomness random: clamp credited irq bits to maximum mixed random: throttle hwrng writes if no entropy is credited random: use hwgenerator randomness more frequently at early boot random: restore O_NONBLOCK support

Pull slab fixes from Vlastimil Babka: - The "common kmalloc v4" series [1] by Hyeonggon Yoo. While the plan after LPC is to try again if it's possible to get rid of SLOB and SLAB (and if any critical aspect of those is not possible to achieve with SLUB today, modify it accordingly), it will take a while even in case there are no objections. Meanwhile this is a nice cleanup and some parts (e.g. to the tracepoints) will be useful even if we end up with a single slab implementation in the future: - Improves the mm/slab_common.c wrappers to allow deleting duplicated code between SLAB and SLUB. - Large kmalloc() allocations in SLAB are passed to page allocator like in SLUB, reducing number of kmalloc caches. - Removes the {kmem_cache_alloc,kmalloc}_node variants of tracepoints, node id parameter added to non-_node variants. - Addition of kmalloc_size_roundup() The first two patches from a series by Kees Cook [2] that introduce kmalloc_size_roundup(). This will allow merging of per-subsystem patches using the new function and ultimately stop (ab)using ksize() in a way that causes ongoing trouble for debugging functionality and static checkers. - Wasted kmalloc() memory tracking in debugfs alloc_traces A patch from Feng Tang that enhances the existing debugfs alloc_traces file for kmalloc caches with information about how much space is wasted by allocations that needs less space than the particular kmalloc cache provides. - My series [3] to fix validation races for caches with enabled debugging: - By decoupling the debug cache operation more from non-debug fastpaths, extra locking simplifications were possible and thus done afterwards. - Additional cleanup of PREEMPT_RT specific code on top, by Thomas Gleixner. - A late fix for slab page leaks caused by the series, by Feng Tang. - Smaller fixes and cleanups: - Unneeded variable removals, by ye xingchen - A cleanup removing a BUG_ON() in create_unique_id(), by Chao Yu Link: https://lore.kernel.org/all/20220817101826.236819-1-42.hyeyoo@gmail.com/ [1] Link: https://lore.kernel.org/all/20220923202822.2667581-1-keescook@chromium.org/ [2] Link: https://lore.kernel.org/all/20220823170400.26546-1-vbabka@suse.cz/ [3] * tag 'slab-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: (30 commits) mm/slub: fix a slab missed to be freed problem slab: Introduce kmalloc_size_roundup() slab: Remove __malloc attribute from realloc functions mm/slub: clean up create_unique_id() mm/slub: enable debugging memory wasting of kmalloc slub: Make PREEMPT_RT support less convoluted mm/slub: simplify __cmpxchg_double_slab() and slab_[un]lock() mm/slub: convert object_map_lock to non-raw spinlock mm/slub: remove slab_lock() usage for debug operations mm/slub: restrict sysfs validation to debug caches and make it safe mm/sl[au]b: check if large object is valid in __ksize() mm/slab_common: move declaration of __ksize() to mm/slab.h mm/slab_common: drop kmem_alloc & avoid dereferencing fields when not using mm/slab_common: unify NUMA and UMA version of tracepoints mm/sl[au]b: cleanup kmem_cache_alloc[_node]_trace() mm/sl[au]b: generalize kmalloc subsystem mm/slub: move free_debug_processing() further mm/sl[au]b: introduce common alloc/free functions without tracepoint mm/slab: kmalloc: pass requests larger than order-1 page to page allocator mm/slab_common: cleanup kmalloc_large() ...
