git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - The series "zram: optimal post-processing target selection" from Sergey Senozhatsky improves zram's post-processing selection algorithm. 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. * tag 'mm-stable-2024-11-18-19-27' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (215 commits) cma: enforce non-zero pageblock_order during cma_init_reserved_mem() mm/kfence: add a new kunit test test_use_after_free_read_nofault() zram: fix NULL pointer in comp_algorithm_show() memcg/hugetlb: add hugeTLB counters to memcg vmstat: call fold_vm_zone_numa_events() before show per zone NUMA event mm: mmap_lock: check trace_mmap_lock_$type_enabled() instead of regcount zram: ZRAM_DEF_COMP should depend on ZRAM MAINTAINERS/MEMORY MANAGEMENT: add document files for mm Docs/mm/damon: recommend academic papers to read and/or cite mm: define general function pXd_init() kmemleak: iommu/iova: fix transient kmemleak false positive mm/list_lru: simplify the list_lru walk callback function mm/list_lru: split the lock to per-cgroup scope mm/list_lru: simplify reparenting and initial allocation mm/list_lru: code clean up for reparenting mm/list_lru: don't export list_lru_add mm/list_lru: don't pass unnecessary key parameters kasan: add kunit tests for kmalloc_track_caller, kmalloc_node_track_caller kasan: change kasan_atomics kunit test as KUNIT_CASE_SLOW kasan: use EXPORT_SYMBOL_IF_KUNIT to export symbols ...

SPI NOR flashes may swap the bytes on a 16-bit boundary when configured in Octal DTR mode. For such cases the byte order is propagated through SPI MEM to the SPI controllers so that the controllers swap the bytes back at runtime. This avoids breaking the boot sequence because of the endianness problems that appear when the bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with byte swap support.

2024-11-22iommu: Rename ops->domain_alloc_user() to domain_alloc_paging_flags()Jason Gunthorpe
Now that the main domain allocating path is calling this function it doesn't make sense to leave it named _user. Change the name to alloc_paging_flags() to mirror the new iommu_paging_domain_alloc_flags() function. A driver should implement only one of ops->domain_alloc_paging() or ops->domain_alloc_paging_flags(). The former is a simpler interface with less boiler plate that the majority of drivers use. The latter is for drivers with a greater feature set (PASID, multiple page table support, advanced iommufd support, nesting, etc). Additional patches will be needed to achieve this.

It turns out all the drivers that are using this immediately call into another function, so just make that function directly into the op. This makes paging=NULL for domain_alloc_user and we can remove the argument in the next patch. The function mirrors the similar op in the viommu that allocates a nested domain on top of the viommu's nesting parent. This version supports cases where a viommu is not being used.

2024-11-22drm/vkms: Re-introduce line-per-line composition algorithmLouis Chauvet
Re-introduce a line-by-line composition algorithm for each pixel format. This allows more performance by not requiring an indirection per pixel read. This patch is focused on readability of the code. Line-by-line composition was introduced by [1] but rewritten back to pixel-by-pixel algorithm in [2]. At this time, nobody noticed the impact on performance, and it was merged. This patch is almost a revert of [2], but in addition efforts have been made to increase readability and maintainability of the rotation handling. The blend function is now divided in two parts: - Transformation of coordinates from the output referential to the source referential - Line conversion and blending Most of the complexity of the rotation management is avoided by using drm_rect_* helpers. The remaining complexity is around the clipping, to avoid reading/writing outside source/destination buffers. The pixel conversion is now done line-by-line, so the read_pixel_t was replaced with read_pixel_line_t callback. This way the indirection is only required once per line and per plane, instead of once per pixel and per plane. The read_line_t callbacks are very similar for most pixel format, but it is required to avoid performance impact. Some helpers for color conversion were introduced to avoid code repetition: - *_to_argb_u16: perform colors conversion. They should be inlined by the compiler, and they are used to avoid repetition between multiple variants of the same format (argb/xrgb and maybe in the future for formats like bgr formats). This new algorithm was tested with: - kms_plane (for color conversions) - kms_rotation_crc (for rotations of planes) - kms_cursor_crc (for translations of planes) - kms_rotation (for all rotations and formats combinations) [3] The performance gain was mesured with kms_fb_stress [4] with some modification to fix the writeback format. The performance improvement is around 5 to 10%.

2024-11-22drm/vkms: Introduce pixel_read_direction enumLouis Chauvet
The pixel_read_direction enum is useful to describe the reading direction in a plane. It avoids using the rotation property of DRM, which not practical to know the direction of reading. This patch also introduce two helpers, one to compute the pixel_read_direction from the DRM rotation property, and one to compute the step, in byte, between two successive pixel in a specific direction.

2024-11-22drm/v3d: Stop active perfmon if it is being destroyedChristian Gmeiner
If the active performance monitor (`v3d->active_perfmon`) is being destroyed, stop it first. Currently, the active perfmon is not stopped during destruction, leaving the `v3d->active_perfmon` pointer stale. This can lead to undefined behavior and instability. This patch ensures that the active perfmon is stopped before being destroyed, aligning with the behavior introduced in commit 7d1fd3638ee3 ("drm/v3d: Stop the active perfmon before being destroyed").

2024-11-22drm/vkms: Remove index parameter from init_vkms_outputLouis Chauvet
VKMS currently supports only one CRTC, so it make no sense to have this index configurable. To avoid issues, replace this hardcoded index by drm_crtc_mask when applicable. There is no need to manually set a crtc mask on primary and cursor plane as it is automatically set by drmm_crtc_alloc_with_planes. In addition, this will remove the use of an uninitialized structure in vkms_add_overlay_plane. This currently works by chance because two things: - vkms_plane_init always set a possible_crtcs value, so the problematic branch is never used; - drm_crtc_mask on an kzalloc'd drm_crtc returns BIT(0), and the VKMS CRTC always have this id.

2024-11-22tpm: atmel: Drop PPC64 specific MMIO setupRob Herring (Arm)
The PPC64 specific MMIO setup open codes DT address functions rather than using standard address parsing functions. The open-coded version fails to handle any address translation and is not endian safe. I haven't found any evidence of what platform used this. The only thing that turned up was a PPC405 platform, but that is 32-bit and PPC405 support is being removed as well. CONFIG_TCG_ATMEL is not enabled for any powerpc config and never was. The support was added in 2005 and hasn't been touched since. Rather than try to modernize and fix this code, just remove it.
