2025-12-19dt-bindings: riscv: add Zilsd and Zclsd extension descriptionsPincheng Wang
Add descriptions for the Zilsd (Load/Store pair instructions) and Zclsd (Compressed Load/Store pair instructions) ISA extensions which were ratified in commit f88abf1 ("Integrating load/store pair for RV32 with the main manual") of the riscv-isa-manual.

2025-12-19riscv: signal: abstract header saving for setup_sigcontextAndy Chiu
The function save_v_state() served two purposes. First, it saved extension context into the signal stack. Then, it constructed the extension header if there was no fault. The second part is independent of the extension itself. As a result, we can pull that part out, so future extensions may reuse it. This patch adds arch_ext_list and makes setup_sigcontext() go through all possible extensions' save() callback. The callback returns a positive value indicating the size of the successfully saved extension. Then the kernel proceeds to construct the header for that extension. The kernel skips an extension if it does not exist, or if the saving fails for some reasons. The error code is propagated out on the later case. This patch does not introduce any functional changes.

2025-12-19crypto: fips - annotate fips_enable() with __init to free init memory after bootCan Peng
The fips_enable() function is only invoked early during kernel boot via the __setup() macro ("fips=" command line parameter), and is never used again after initialization completes. Annotating it with __init places the function in the .init.text section, allowing the kernel to free its memory after init (when freeing_initmem() runs), reducing runtime memory footprint. This is a standard practice for setup/early-parse functions and has no functional impact — the parsing logic, return values, and fips mode setting behavior remain unchanged.

If no empty compression mode can be found, the function would return the out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid array access in add_iaa_compression_mode().

2025-12-19crypto: octeontx - Fix length check to avoid truncation in ucode_load_storeThorsten Blum
OTX_CPT_UCODE_NAME_LENGTH limits the microcode name to 64 bytes. If a user writes a string of exactly 64 characters, the original code used 'strlen(buf) > 64' to check the length, but then strscpy() copies only 63 characters before adding a NUL terminator, silently truncating the copied string. Fix this off-by-one error by using 'count' directly for the length check to ensure long names are rejected early and copied without truncation.

2025-12-18Input: psmouse-smbus - add WQ_UNBOUND to alloc_workqueue userMarco Crivellari
Currently if a user enqueue a work item using schedule_delayed_work() the used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to schedule_work() that is using system_wq and queue_work(), that makes use again of WORK_CPU_UNBOUND. This lack of consistentcy cannot be addressed without refactoring the API. alloc_workqueue() treats all queues as per-CPU by default, while unbound workqueues must opt-in via WQ_UNBOUND. This default is suboptimal: most workloads benefit from unbound queues, allowing the scheduler to place worker threads where they’re needed and reducing noise when CPUs are isolated. This patch continues the effort to refactor worqueue APIs, which has begun with the change introducing new workqueues and a new alloc_workqueue flag: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This specific workload do not benefit from a per-cpu workqueue, so use WQ_UNBOUND on the custom workqueue instead. With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND), any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND must now use WQ_PERCPU. Once migration is complete, WQ_UNBOUND can be removed and unbound will become the implicit default.

2025-12-18x86/irq_remapping: Sanitize posted_msi_supported()Thomas Gleixner
posted_msi_supported() is a misnomer as it actually checks whether it is enabled or not. Aside of that this does not take CONFIG_X86_POSTED_MSI into account which is required to actually use it. Rename it to posted_msi_enabled() and make the return value depend on CONFIG_X86_POSTED_MSI, which allows the compiler to eliminate the related dead code and data if disabled: text data bss dec hex filename 10046 701 3296 14043 36db drivers/iommu/intel/irq_remapping.o 9904 413 3296 13613 352d drivers/iommu/intel/irq_remapping.o Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://patch.msgid.link/20251125214631.170499997@linutronix.de

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Add Documentation/core-api/tracepoint.rst to TRACING in MAINTAINERS file Updates to the tracepoint.rst document should be reviewed by the tracing maintainers. - Fix warning triggered by perf attaching to synthetic events The synthetic events do not add a function to be registered when perf attaches to them. This causes a warning when perf registers a synthetic event and passes a NULL pointer to the tracepoint register function. Ideally synthetic events should be updated to work with perf, but as that's a feature and not a bug fix, simply now return -ENODEV when perf tries to register an event that has a NULL pointer for its function. This no longer causes a kernel warning and simply causes the perf code to fail with an error message. - Fix 32bit overflow in option flag test The option's flags changed from 32 bits in size to 64 bits in size. Fix one of the places that shift 1 by the option bit number to to be 1ULL. - Fix the output of printing the direct jmp functions The enabled_functions that shows how functions are being attached by ftrace wasn't updated to accommodate the new direct jmp trampolines that set the LSB of the pointer, and outputs garbage. Update the output to handle the direct jmp trampolines. * tag 'trace-v6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ftrace: Fix address for jmp mode in t_show() tracing: Fix UBSAN warning in __remove_instance() tracing: Do not register unsupported perf events MAINTAINERS: add tracepoint core-api doc files to TRACING

2025-12-18Input: apple_z2 - fix reading incorrect reports after exiting sleepSasha Finkelstein
Under certain conditions (more prevalent after a suspend/resume cycle), the touchscreen controller can send the "boot complete" interrupt before it actually finished booting. In those cases, attempting to read touch data resuls in a stream of "not ready" messages being read and interpreted as a touch report. Check that the response is in fact a touch report and discard it otherwise.
