git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull mm updates from Andrew Morton: "The usual shower of singleton fixes and minor series all over MM, documented (hopefully adequately) in the respective changelogs. Notable series include: - Lucas Stach has provided some page-mapping cleanup/consolidation/ maintainability work in the series "mm/treewide: Remove pXd_huge() API". - In the series "Allow migrate on protnone reference with MPOL_PREFERRED_MANY policy", Donet Tom has optimized mempolicy's MPOL_PREFERRED_MANY mode, yielding almost doubled performance in one test. - In their series "Memory allocation profiling" Kent Overstreet and Suren Baghdasaryan have contributed a means of determining (via /proc/allocinfo) whereabouts in the kernel memory is being allocated: number of calls and amount of memory. - Matthew Wilcox has provided the series "Various significant MM patches" which does a number of rather unrelated things, but in largely similar code sites. - In his series "mm: page_alloc: freelist migratetype hygiene" Johannes Weiner has fixed the page allocator's handling of migratetype requests, with resulting improvements in compaction efficiency. - In the series "make the hugetlb migration strategy consistent" Baolin Wang has fixed a hugetlb migration issue, which should improve hugetlb allocation reliability. - Liu Shixin has hit an I/O meltdown caused by readahead in a memory-tight memcg. Addressed in the series "Fix I/O high when memory almost met memcg limit". - In the series "mm/filemap: optimize folio adding and splitting" Kairui Song has optimized pagecache insertion, yielding ~10% performance improvement in one test. - Baoquan He has cleaned up and consolidated the early zone initialization code in the series "mm/mm_init.c: refactor free_area_init_core()". - Baoquan has also redone some MM initializatio code in the series "mm/init: minor clean up and improvement". - MM helper cleanups from Christoph Hellwig in his series "remove follow_pfn". - More cleanups from Matthew Wilcox in the series "Various page->flags cleanups". - Vlastimil Babka has contributed maintainability improvements in the series "memcg_kmem hooks refactoring". - More folio conversions and cleanups in Matthew Wilcox's series: "Convert huge_zero_page to huge_zero_folio" "khugepaged folio conversions" "Remove page_idle and page_young wrappers" "Use folio APIs in procfs" "Clean up __folio_put()" "Some cleanups for memory-failure" "Remove page_mapping()" "More folio compat code removal" - David Hildenbrand chipped in with "fs/proc/task_mmu: convert hugetlb functions to work on folis". - Code consolidation and cleanup work related to GUP's handling of hugetlbs in Peter Xu's series "mm/gup: Unify hugetlb, part 2". - Rick Edgecombe has developed some fixes to stack guard gaps in the series "Cover a guard gap corner case". - Jinjiang Tu has fixed KSM's behaviour after a fork+exec in the series "mm/ksm: fix ksm exec support for prctl". - Baolin Wang has implemented NUMA balancing for multi-size THPs.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "There's one API update here, a new API factoring out a common pattern for reference voltage supplies. These are supplies used as a reference by analogue circuits where the consumer requests and enables the supply, reads the voltage to calibrate the user and then never touches it again. This is factored out into a single operation which just returns the voltage and uses devm_ to manage the request and enable portion. Otherwise this has been a very quiet release, we've got some new device support, some small fixes, housekeeping and cleanup work but nothing substantial. There's also some non-regulator changes in here, a number of users for the new reference voltage API were merged along with it and some MFD changes were pulled in as dependencies for new driver work.

This topic came up again when Paul McKenney noticed that parts of the RCU code already rely on byte access and do not work on alpha EV5 reliably, so we decided on using my series to avoid the problem entirely. Al Viro did another series for alpha to address all the known build issues. I rebased his patches without any further changes and included it as a baseline for my work here to avoid conflicts and allow backporting the fixes to stable kernels for the now removed hardware support as well" [ I dearly loved alpha back in the days, but the lack of byte and word operations was a horrible mistake and made everything worse - including very much the crazy IO contortions that resulted from it. It certainly wasn't the only mistake in the architecture, but it's the first-order issue.

2024-05-05mm: zswap: remove same_filled module paramsYosry Ahmed1-2/+0
These knobs offer more fine-grained control to userspace than needed and directly expose/influence kernel implementation; remove them. For disabling same_filled handling, there is no logical reason to refuse storing same-filled pages more efficiently and opt for compression. Scanning pages for patterns may be an argument, but the page contents will be read into the CPU cache anyway during compression. Also, removing the same_filled handling code does not move the needle significantly in terms of performance anyway [1]. For disabling non_same_filled handling, it was added when the compressed pages in zswap were not being properly charged to memcgs, as workloads could escape the accounting with compression [2]. This is no longer the case after commit f4840ccfca25 ("zswap: memcg accounting"), and using zswap without compression does not make much sense.

2024-04-23fpga: region: add owner module and take its refcountMarco Pagani1-5/+8
The current implementation of the fpga region assumes that the low-level module registers a driver for the parent device and uses its owner pointer to take the module's refcount. This approach is problematic since it can lead to a null pointer dereference while attempting to get the region during programming if the parent device does not have a driver. To address this problem, add a module owner pointer to the fpga_region struct and use it to take the module's refcount. Modify the functions for registering a region to take an additional owner module parameter and rename them to avoid conflicts. Use the old function names for helper macros that automatically set the module that registers the region as the owner. This ensures compatibility with existing low-level control modules and reduces the chances of registering a region without setting the owner. Also, update the documentation to keep it consistent with the new interface for registering an fpga region.

2024-04-08virtio: store owner from modules with register_virtio_driver()Krzysztof Kozlowski1-1/+0
Modules registering driver with register_virtio_driver() might forget to set .owner field. i2c-virtio.c for example has it missing. The field is used by some other kernel parts for reference counting (try_module_get()), so it is expected that drivers will set it. Solve the problem by moving this task away from the drivers to the core virtio code, just like we did for platform_driver in commit 9447057eaff8 ("platform_device: use a macro instead of platform_driver_register").

Since these are all read-only, there's really no reason to have them as separate files, especially since we already display them as global stats in the wq_stats.
