Prior to clang 22.0.0 [1], ARM did not have an architecture specific kCFI bundle lowering in the backend, which may cause issues. Select CONFIG_ARCH_USES_CFI_GENERIC_LLVM_PASS to enable use of __nocfi_generic.

2025-10-15Remove long-stale ext3 defconfig optionLinus Torvalds1-1/+0
Inspired by commit c065b6046b34 ("Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs") I looked around for any other left-over EXT3 config options, and found some old defconfig files still mentioned CONFIG_EXT3_DEFAULTS_TO_ORDERED. That config option was removed a decade ago in commit c290ea01abb7 ("fs: Remove ext3 filesystem driver"). It had a good run, but let's remove it for good.

2025-10-13Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigsTheodore Ts'o30-48/+48
Commit d6ace46c82fd ("ext4: remove obsolete EXT3 config options") removed the obsolete EXT3_CONFIG options, since it had been over a decade since fs/ext3 had been removed. Unfortunately, there were a number of defconfigs that still used CONFIG_EXT3_FS which the cleanup commit didn't fix up. This led to a large number of defconfig test builds to fail. Oops.

2025-10-13ARM: dts: broadcom: rpi: Switch to V3D firmware clockStefan Wahren2-0/+17
Until commit 919d6924ae9b ("clk: bcm: rpi: Turn firmware clock on/off when preparing/unpreparing") the clk-raspberrypi driver wasn't able to change the state of the V3D clock. Only the clk-bcm2835 was able to do this before. After this commit both drivers were able to work against each other, which could result in a system freeze. One step to avoid this conflict is to switch all V3D consumer to the firmware clock.

To end the constant struggle with space shortage on 32-bit conflicting with 64-bit's needs - "mm/swapfile.c and swap.h cleanup" from Chris Li cleans up some swap code - "selftests/mm: Fix false positives and skip unsupported tests" from Donet Tom fixes a few things in our selftests code - "prctl: extend PR_SET_THP_DISABLE to only provide THPs when advised" from David Hildenbrand "allows individual processes to opt-out of THP=always into THP=madvise, without affecting other workloads on the system". It's a long story - the [1/N] changelog spells out the considerations - "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on the memdesc project. Please see https://kernelnewbies.org/MatthewWilcox/Memdescs and https://blogs.oracle.com/linux/post/introducing-memdesc - "Tiny optimization for large read operations" from Chi Zhiling improves the efficiency of the pagecache read path - "Better split_huge_page_test result check" from Zi Yan improves our folio splitting selftest code - "test that rmap behaves as expected" from Wei Yang adds some rmap selftests - "remove write_cache_pages()" from Christoph Hellwig removes that function and converts its two remaining callers - "selftests/mm: uffd-stress fixes" from Dev Jain fixes some UFFD selftests issues - "introduce kernel file mapped folios" from Boris Burkov introduces the concept of "kernel file pages". Using these permits btrfs to account its metadata pages to the root cgroup, rather than to the cgroups of random inappropriate tasks - "mm/pageblock: improve readability of some pageblock handling" from Wei Yang provides some readability improvements to the page allocator code - "mm/damon: support ARM32 with LPAE" from SeongJae Park teaches DAMON to understand arm32 highmem - "tools: testing: Use existing atomic.h for vma/maple tests" from Brendan Jackman performs some code cleanups and deduplication under tools/testing/ - "maple_tree: Fix testing for 32bit compiles" from Liam Howlett fixes a couple of 32-bit issues in tools/testing/radix-tree.c - "kasan: unify kasan_enabled() and remove arch-specific implementations" from Sabyrzhan Tasbolatov moves KASAN arch-specific initialization code into a common arch-neutral implementation - "mm: remove zpool" from Johannes Weiner removes zspool - an indirection layer which now only redirects to a single thing (zsmalloc) - "mm: task_stack: Stack handling cleanups" from Pasha Tatashin makes a couple of cleanups in the fork code - "mm: remove nth_page()" from David Hildenbrand makes rather a lot of adjustments at various nth_page() callsites, eventually permitting the removal of that undesirable helper function - "introduce kasan.write_only option in hw-tags" from Yeoreum Yun creates a KASAN read-only mode for ARM, using that architecture's memory tagging feature. It is felt that a read-only mode KASAN is suitable for use in production systems rather than debug-only - "mm: hugetlb: cleanup hugetlb folio allocation" from Kefeng Wang does some tidying in the hugetlb folio allocation code - "mm: establish const-correctness for pointer parameters" from Max Kellermann makes quite a number of the MM API functions more accurate about the constness of their arguments. This was getting in the way of subsystems (in this case CEPH) when they attempt to improving their own const/non-const accuracy - "Cleanup free_pages() misuse" from Vishal Moola fixes a number of code sites which were confused over when to use free_pages() vs __free_pages() - "Add Rust abstraction for Maple Trees" from Alice Ryhl makes the mapletree code accessible to Rust. Required by nouveau and by its forthcoming successor: the new Rust Nova driver - "selftests/mm: split_huge_page_test: split_pte_mapped_thp improvements" from David Hildenbrand adds a fix and some cleanups to the thp selftesting code - "mm, swap: introduce swap table as swap cache (phase I)" from Chris Li and Kairui Song is the first step along the path to implementing "swap tables" - a new approach to swap allocation and state tracking which is expected to yield speed and space improvements. This patchset itself yields a 5-20% performance benefit in some situations - "Some ptdesc cleanups" from Matthew Wilcox utilizes the new memdesc layer to clean up the ptdesc code a little - "Fix va_high_addr_switch.sh test failure" from Chunyu Hu fixes some issues in our 5-level pagetable selftesting code - "Minor fixes for memory allocation profiling" from Suren Baghdasaryan addresses a couple of minor issues in relatively new memory allocation profiling feature - "Small cleanups" from Matthew Wilcox has a few cleanups in preparation for more memdesc work - "mm/damon: add addr_unit for DAMON_LRU_SORT and DAMON_RECLAIM" from Quanmin Yan makes some changes to DAMON in furtherance of supporting arm highmem - "selftests/mm: Add -Wunreachable-code and fix warnings" from Muhammad Anjum adds that compiler check to selftests code and fixes the fallout, by removing dead code - "Improvements to Victim Process Thawing and OOM Reaper Traversal Order" from zhongjinji makes a number of improvements in the OOM killer: mainly thawing a more appropriate group of victim threads so they can release resources - "mm/damon: misc fixups and improvements for 6.18" from SeongJae Park is a bunch of small and unrelated fixups for DAMON - "mm/damon: define and use DAMON initialization check function" from SeongJae Park implement reliability and maintainability improvements to a recently-added bug fix - "mm/damon/stat: expose auto-tuned intervals and non-idle ages" from SeongJae Park provides additional transparency to userspace clients of the DAMON_STAT information - "Expand scope of khugepaged anonymous collapse" from Dev Jain removes some constraints on khubepaged's collapsing of anon VMAs. It also increases the success rate of MADV_COLLAPSE against an anon vma - "mm: do not assume file == vma->vm_file in compat_vma_mmap_prepare()" from Lorenzo Stoakes moves us further towards removal of file_operations.mmap(). This patchset concentrates upon clearing up the treatment of stacked filesystems - "mm: Improve mlock tracking for large folios" from Kiryl Shutsemau provides some fixes and improvements to mlock's tracking of large folios. /proc/meminfo's "Mlocked" field became more accurate - "mm/ksm: Fix incorrect accounting of KSM counters during fork" from Donet Tom fixes several user-visible KSM stats inaccuracies across forks and adds selftest code to verify these counters - "mm_slot: fix the usage of mm_slot_entry" from Wei Yang addresses some potential but presently benign issues in KSM's mm_slot handling * tag 'mm-stable-2025-10-01-19-00' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (372 commits) mm: swap: check for stable address space before operating on the VMA mm: convert folio_page() back to a macro mm/khugepaged: use start_addr/addr for improved readability hugetlbfs: skip VMAs without shareable locks in hugetlb_vmdelete_list alloc_tag: fix boot failure due to NULL pointer dereference mm: silence data-race in update_hiwater_rss mm/memory-failure: don't select MEMORY_ISOLATION mm/khugepaged: remove definition of struct khugepaged_mm_slot mm/ksm: get mm_slot by mm_slot_entry() when slot is !NULL hugetlb: increase number of reserving hugepages via cmdline selftests/mm: add fork inheritance test for ksm_merging_pages counter mm/ksm: fix incorrect KSM counter handling in mm_struct during fork drivers/base/node: fix double free in register_one_node() mm: remove PMD alignment constraint in execmem_vmalloc() mm/memory_hotplug: fix typo 'esecially' -> 'especially' mm/rmap: improve mlock tracking for large folios mm/filemap: map entire large folio faultaround mm/fault: try to map the entire file folio in finish_fault() mm/rmap: mlock large folios in try_to_unmap_one() mm/rmap: fix a mlock race condition in folio_referenced_one() ...

git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux Pull block updates from Jens Axboe: - NVMe pull request via Keith: - FC target fixes (Daniel) - Authentication fixes and updates (Martin, Chris) - Admin controller handling (Kamaljit) - Target lockdep assertions (Max) - Keep-alive updates for discovery (Alastair) - Suspend quirk (Georg) - MD pull request via Yu: - Add support for a lockless bitmap. A key feature for the new bitmap are that the IO fastpath is lockless. If a user issues lots of write IO to the same bitmap bit in a short time, only the first write has additional overhead to update bitmap bit, no additional overhead for the following writes. By supporting only resync or recover written data, means in the case creating new array or replacing with a new disk, there is no need to do a full disk resync/recovery. - Switch ->getgeo() and ->bios_param() to using struct gendisk rather than struct block_device. - Rust block changes via Andreas. This series adds configuration via configfs and remote completion to the rnull driver. The series also includes a set of changes to the rust block device driver API: a few cleanup patches, and a few features supporting the rnull changes. The series removes the raw buffer formatting logic from `kernel::block` and improves the logic available in `kernel::string` to support the same use as the removed logic. - floppy arch cleanups - Reduce the number of dereferencing needed for ublk commands - Restrict supported sockets for nbd. Mostly done to eliminate a class of issues perpetually reported by syzbot, by using nonsensical socket setups. - A few s390 dasd block fixes - Fix a few issues around atomic writes - Improve DMA interation for integrity requests - Improve how iovecs are treated with regards to O_DIRECT aligment constraints. We used to require each segment to adhere to the constraints, now only the request as a whole needs to. - Clean up and improve p2p support, enabling use of p2p for metadata payloads - Improve locking of request lookup, using SRCU where appropriate - Use page references properly for brd, avoiding very long RCU sections - Fix ordering of recursively submitted IOs - Clean up and improve updating nr_requests for a live device - Various fixes and cleanups * tag 'for-6.18/block-20250929' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux: (164 commits) s390/dasd: enforce dma_alignment to ensure proper buffer validation s390/dasd: Return BLK_STS_INVAL for EINVAL from do_dasd_request ublk: remove redundant zone op check in ublk_setup_iod() nvme: Use non zero KATO for persistent discovery connections nvmet: add safety check for subsys lock nvme-core: use nvme_is_io_ctrl() for I/O controller check nvme-core: do ioccsz/iorcsz validation only for I/O controllers nvme-core: add method to check for an I/O controller blk-cgroup: fix possible deadlock while configuring policy blk-mq: fix null-ptr-deref in blk_mq_free_tags() from error path blk-mq: Fix more tag iteration function documentation selftests: ublk: fix behavior when fio is not installed ublk: don't access ublk_queue in ublk_unmap_io() ublk: pass ublk_io to __ublk_complete_rq() ublk: don't access ublk_queue in ublk_need_complete_req() ublk: don't access ublk_queue in ublk_check_commit_and_fetch() ublk: don't pass ublk_queue to ublk_fetch() ublk: don't access ublk_queue in ublk_config_io_buf() ublk: don't access ublk_queue in ublk_check_fetch_buf() ublk: pass q_id and tag to __ublk_check_and_get_req() ...

Pull SoC dt updates from Arnd Bergmann: "There are five sets of new SoCs that get added in existing families, all of them being either upgrades or cut-down versions of the older chips: - Apple M2 Pro, M2 Max and M2 Ultra, used in the 2022/2023 generation of high-end workstations and laptops from Apple. Linux has been working on these for a while but stil requires patches. - Axis Artpec8 is an Armv8 chip based on Samsung Exynos design, unlike the earlier Armv7 Artpec6 from the same company that was part of a separate family of chips. - NXP i.MX91 is a cut-down version of i.MX93, using only a single Cortex-A55 core. - Qualcomm Lemans Auto is a variant of the Lemans SoC that was originally merged under the sa8775p name, the differences being mostly the firmware configuration of the platform. - Four new Renesas SoCs RZ/T2H (r9a09g077m44), RZ/N2H (r9a09g087m44), RZ/T2H (r9a09g077), and RZ/N2H (r9a09g087) are all industrial bedded SoCs based on Cortex-A55 cores In total, there are 65 new machines, including: - Industrial embedded system and single-board computers based on NXP, Allwinner, TI, Rockchips, Marvell, Xilinx Spacemit, Starfive chips. - Reference boards for the newly added Renesas, Qualcomm, NXP and Axis ARMv8 chips as well as Microchip's MPFS RISC-V SoC - Laptops and Workstations using Apple M2 and Qualcomm Snapdragon X1 chips. - Several Samsung phones using Qualcomm Snapdragon chips - Set-top boxes based on Allwinner H313 - Five BMC boards using 32-bit ASpeed SoCs - Three network routers using IXP4xx (ARMv5!) and Broadcom bcm4708 (ARMv7) SoCs Two machines get phased out because they were available only in small quantities but never made it into products: one STi407 based reference board, and a Snapdragon 845 based Chromebook.

2025-09-25arch: Add the macro COMPILE_OFFSETS to all the asm-offsets.cMenglong Dong1-0/+2
The include/generated/asm-offsets.h is generated in Kbuild during compiling from arch/SRCARCH/kernel/asm-offsets.c. When we want to generate another similar offset header file, circular dependency can happen. For example, we want to generate a offset file include/generated/test.h, which is included in include/sched/sched.h. If we generate asm-offsets.h first, it will fail, as include/sched/sched.h is included in asm-offsets.c and include/generated/test.h doesn't exist; If we generate test.h first, it can't success neither, as include/generated/asm-offsets.h is included by it. In x86_64, the macro COMPILE_OFFSETS is used to avoid such circular dependency. We can generate asm-offsets.h first, and if the COMPILE_OFFSETS is defined, we don't include the "generated/test.h". And we define the macro COMPILE_OFFSETS for all the asm-offsets.c for this purpose. Signed-off-by: Menglong Dong <dongml2@chinatelecom.cn> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>

https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into soc/dt Allwinner Device Tree changes for 6.18 This tag contains two DT binding header changes that are shared with the clk tree. In this cycle we gained support for the MCU PRCM clock and reset controller on the A523/A527/T527 family of SoCs, the NPU which is a Vivante GC9000 IP block, and the NPU clock that was missing. The other PRCM clock controller gained default bus clock rate settings. These were not configured in the upstream U-boot bootloader, leading to them running at slower rates. The assigned rates are from the user manual. There is also a new board, the NetCube Systems Nagami SoM and two of its carrier boards. The A523 family development boards now have their internal RTC clocks configured correctly, so that the RTC does not drift wildly. The missing functions for the AXP717 on these boards are added. Missing reset GPIOs and delays for Ethernet PHYs are added. Last, the Cubie A5E now has its LEDs described and usable. An overlay for the Orange Pi Zero interface (addon) board was added. This can be used with the Orange Pi Zero and Zero Plus 2. Default audio routing for these two boards (to be used with the addon) were added to complement the overlay. * tag 'sunxi-dt-for-6.18' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux: arm64: dts: allwinner: sun55i: Complete AXP717A sub-functions arm64: dts: allwinner: t527: orangepi-4a: hook up external 32k crystal arm64: dts: allwinner: t527: avaota-a1: hook up external 32k crystal arm64: dts: allwinner: a527: cubie-a5e: Drop external 32.768 KHz crystal arm64: dts: sun55i: a523: Assign standard clock rates to PRCM bus clocks ARM: dts: sunxi: add support for NetCube Systems Nagami Keypad Carrier ARM: dts: sunxi: add support for NetCube Systems Nagami Basic Carrier ARM: dts: sunxi: add support for NetCube Systems Nagami SoM riscv: dts: allwinner: d1s-t113: Add pinctrl's required by NetCube Systems Nagami SoM dt-bindings: arm: sunxi: Add NetCube Systems Nagami SoM and carrier board bindings ARM: dts: allwinner: Add Orange Pi Zero Interface Board overlay ARM: dts: allwinner: orangepi-zero-plus2: Add default audio routing ARM: dts: allwinner: orangepi-zero: Add default audio routing arm64: dts: allwinner: a523: Add NPU device node arm64: dts: allwinner: a523: Add MCU PRCM CCU node dt-bindings: clock: sun55i-a523-ccu: Add A523 MCU CCU clock controller dt-bindings: clock: sun55i-a523-ccu: Add missing NPU module clock arm64: dts: allwinner: t527: avaota-a1: Add ethernet PHY reset setting arm64: dts: allwinner: a527: cubie-a5e: Add ethernet PHY reset setting arm64: dts: allwinner: a527: cubie-a5e: Add LEDs Link: https://lore.kernel.org/r/aMrtuZg8HlR--TAt@wens.tw Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2025-09-21mm: constify highmem related functions for improved const-correctnessMax Kellermann1-3/+3
Lots of functions in mm/highmem.c do not write to the given pointers and do not call functions that take non-const pointers and can therefore be constified. This includes functions like kunmap() which might be implemented in a way that writes to the pointer (e.g. to update reference counters or mapping fields), but currently are not. kmap() on the other hand cannot be made const because it calls set_page_address() which is non-const in some architectures/configurations.
