Merge tag 'mm-nonmm-stable-2026-04-15-04-20' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mmPull non-MM updates from Andrew Morton: - "pid: make sub-init creation retryable" (Oleg Nesterov) Make creation of init in a new namespace more robust by clearing away some historical cruft which is no longer needed. Also some documentation fixups - "selftests/fchmodat2: Error handling and general" (Mark Brown) Fix and a cleanup for the fchmodat2() syscall selftest - "lib: polynomial: Move to math/ and clean up" (Andy Shevchenko) - "hung_task: Provide runtime reset interface for hung task detector" (Aaron Tomlin) Give administrators the ability to zero out /proc/sys/kernel/hung_task_detect_count - "tools/getdelays: use the static UAPI headers from tools/include/uapi" (Thomas Weißschuh) Teach getdelays to use the in-kernel UAPI headers rather than the system-provided ones - "watchdog/hardlockup: Improvements to hardlockup" (Mayank Rungta) Several cleanups and fixups to the hardlockup detector code and its documentation - "lib/bch: fix undefined behavior from signed left-shifts" (Josh Law) A couple of small/theoretical fixes in the bch code - "ocfs2/dlm: fix two bugs in dlm_match_regions()" (Junrui Luo) - "cleanup the RAID5 XOR library" (Christoph Hellwig) A quite far-reaching cleanup to this code. I can't do better than to quote Christoph: "The XOR library used for the RAID5 parity is a bit of a mess right now. The main file sits in crypto/ despite not being cryptography and not using the crypto API, with the generic implementations sitting in include/asm-generic and the arch implementations sitting in an asm/ header in theory. The latter doesn't work for many cases, so architectures often build the code directly into the core kernel, or create another module for the architecture code. Change this to a single module in lib/ that also contains the architecture optimizations, similar to the library work Eric Biggers has done for the CRC and crypto libraries later. After that it changes to better calling conventions that allow for smarter architecture implementations (although none is contained here yet), and uses static_call to avoid indirection function call overhead" - "lib/list_sort: Clean up list_sort() scheduling workarounds" (Kuan-Wei Chiu) Clean up this library code by removing a hacky thing which was added for UBIFS, which UBIFS doesn't actually need - "Fix bugs in extract_iter_to_sg()" (Christian Ehrhardt) Fix a few bugs in the scatterlist code, add in-kernel tests for the now-fixed bugs and fix a leak in the test itself - "kdump: Enable LUKS-encrypted dump target support in ARM64 and PowerPC" (Coiby Xu) Enable support of the LUKS-encrypted device dump target on arm64 and powerpc - "ocfs2: consolidate extent list validation into block read callbacks" (Joseph Qi) Cleanup, simplify, and make more robust ocfs2's validation of extent list fields (Kernel test robot loves mounting corrupted fs images!)* tag 'mm-nonmm-stable-2026-04-15-04-20' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (127 commits) ocfs2: validate group add input before caching ocfs2: validate bg_bits during freefrag scan ocfs2: fix listxattr handling when the buffer is full doc: watchdog: fix typos etc update Sean's email address ocfs2: use get_random_u32() where appropriate ocfs2: split transactions in dio completion to avoid credit exhaustion ocfs2: remove redundant l_next_free_rec check in __ocfs2_find_path() ocfs2: validate extent block list fields during block read ocfs2: remove empty extent list check in ocfs2_dx_dir_lookup_rec() ocfs2: validate dx_root extent list fields during block read ocfs2: fix use-after-free in ocfs2_fault() when VM_FAULT_RETRY ocfs2: handle invalid dinode in ocfs2_group_extend .get_maintainer.ignore: add Askar ocfs2: validate bg_list extent bounds in discontig groups checkpatch: exclude forward declarations of const structs tools/accounting: handle truncated taskstats netlink messages taskstats: set version in TGID exit notifications ocfs2/heartbeat: fix slot mapping rollback leaks on error paths arm64,ppc64le/kdump: pass dm-crypt keys to kdump kernel ...

Mon, 23 Feb 2026 03:59:14 +0000

kernel/panic: mark init_taint_buf as __initdata and panic instead of warning in alloc_taint_buf()However there's a convention of assuming that __init-time allocationscannot fail. Because if a kmalloc() were to fail at this time, the kernelis hopelessly messed up anyway. So simply panic() if that kmalloc failed,then make that 350-byte buffer __initdata.Link: https://lkml.kernel.org/r/20260223035914.4033-1-rioo.tsukatsukii@gmail.comSigned-off-by: Rio Cc: Joel Granados Cc: Petr Mladek Cc: Wang Jinchao Signed-off-by: Andrew Morton List of files: /linux/kernel/panic.c

Sun, 22 Feb 2026 14:08:04 +0000

kernel/panic: allocate taint string buffer dynamicallyThe buffer used to hold the taint string is statically allocated, whichrequires updating whenever a new taint flag is added.Instead, allocate the exact required length at boot once the allocator isavailable in an init function. The allocation sums the string lengths intaint_flags[], along with space for separators and formatting. print_tainted() is switched to use this dynamically allocated buffer.If allocation fails, print_tainted() warns about the failure and continuesto use the original static buffer as a fallback.Link: https://lkml.kernel.org/r/20260222140804.22225-1-rioo.tsukatsukii@gmail.comSigned-off-by: Rio Cc: Joel Granados Cc: Petr Mladek Cc: Wang Jinchao Signed-off-by: Andrew Morton List of files: /linux/kernel/panic.c

2e171ab29f916455a49274a2042bac4a4b35570e - panic: add panic_force_cpu= parameter to redirect panic to a specific CPU

Thu, 22 Jan 2026 10:24:57 +0000

panic: add panic_force_cpu= parameter to redirect panic to a specific CPUSome platforms require panic handling to execute on a specific CPU forcrash dump to work reliably. This can be due to firmware limitations,interrupt routing constraints, or platform-specific requirements whereonly a single CPU is able to safely enter the crash kernel.Add the panic_force_cpu= kernel command-line parameter to redirect panicexecution to a designated CPU. When the parameter is provided, the CPUthat initially triggers panic forwards the panic context to the target CPUvia IPI, which then proceeds with the normal panic and kexec flow.The IPI delivery is implemented as a weak function(panic_smp_redirect_cpu) so architectures with NMI support can override itfor more reliable delivery.If the specified CPU is invalid, offline, or a panic is already inprogress on another CPU, the redirection is skipped and panic continues onthe current CPU.[pnina.feder@mobileye.com: fix unused variable warning] Link: https://lkml.kernel.org/r/20260126122618.2967950-1-pnina.feder@mobileye.comLink: https://lkml.kernel.org/r/20260122102457.1154599-1-pnina.feder@mobileye.comSigned-off-by: Pnina Feder Reviewed-by: Petr Mladek Cc: Baoquan He Cc: Ingo Molnar Cc: Jonathan Corbet Cc: Mel Gorman Cc: Peter Zijlstra Cc: Sergey Senozhatsky Cc: Steven Rostedt Cc: Thomas Gleixner Signed-off-by: Andrew Morton List of files: /linux/kernel/panic.c

spi: aspeed: Improve handling of shared SPIMerge series from Chin-Ting Kuo :This patch series improves handling of SPI controllers that areshared by spi-mem devices and other SPI peripherals.The primary goal of this series is to support non-spi-mem devices inthe ASPEED FMC/SPI controller driver. It also addresses an issue inthe spi-mem framework observed when different types of SPI devicesoperate concurrently on the same controller, ensuring that spi-memoperations are properly serialized.
