2025-11-11arm64/efi: Move uaccess en/disable out of efi_set_pgd()Ard Biesheuvel
efi_set_pgd() will no longer be called when invoking EFI runtime services via the efi_rts_wq work queue, but the uaccess en/disable are still needed when using PAN emulation using TTBR0 switching. So move these into the callers.

2025-11-11arm64/efi: Drop efi_rt_lock spinlock from EFI arch wrapperArd Biesheuvel
Since commit 5894cf571e14 ("acpi/prmt: Use EFI runtime sandbox to invoke PRM handlers") all EFI runtime calls on arm64 are routed via the EFI runtime wrappers, which are serialized using the efi_runtime_lock semaphore. This means the efi_rt_lock spinlock in the arm64 arch wrapper code has become redundant, and can be dropped. For robustness, replace it with an assert that the EFI runtime lock is in fact held by 'current'.

2025-11-11arm64/fpsimd: Permit kernel mode NEON with IRQs offArd Biesheuvel
Currently, may_use_simd() will return false when called from a context where IRQs are disabled. One notable case where this happens is when calling the ResetSystem() EFI runtime service from the reboot/poweroff code path. For this case alone, there is a substantial amount of FP/SIMD support code to handle the corner case where a EFI runtime service is invoked with IRQs disabled. The only reason kernel mode SIMD is not allowed when IRQs are disabled is that re-enabling softirqs in this case produces a noisy diagnostic when lockdep is enabled. The warning is valid, in the sense that delivering pending softirqs over the back of the call to local_bh_enable() is problematic when IRQs are disabled. While the API lacks a facility to simply mask and unmask softirqs without triggering their delivery, disabling softirqs is not needed to begin with when IRQs are disabled, given that softirqs are only every taken asynchronously over the back of a hard IRQ. So dis/enable softirq processing conditionally, based on whether IRQs are enabled, and relax the check in may_use_simd().

2025-11-11efi/runtime-wrappers: Keep track of the efi_runtime_lock ownerArd Biesheuvel
The EFI runtime wrappers use a file local semaphore to serialize access to the EFI runtime services. This means that any calls to the arch wrappers around the runtime services will also be serialized, removing the need for redundant locking. For robustness, add a facility that allows those arch wrappers to assert that the semaphore was taken by the current task.

git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Will Deacon: "There's more here than I would ideally like at this stage, but there's been a steady trickle of fixes and some of them took a few rounds of review. The bulk of the changes are fixing some fallout from the recent BBM level two support which allows the linear map to be split from block to page mappings at runtime, but inadvertently led to sleeping in atomic context on some paths where the linear map was already mapped with page granularity. The fix is simply to avoid splitting in those cases but the implementation of that is a little involved. The other interesting fix is addressing a catastophic performance issue with our per-cpu atomics discovered by Paul in the SRCU locking code but which took some interactions with the hardware folks to resolve. Summary: - Avoid sleeping in atomic context when changing linear map permissions for DEBUG_PAGEALLOC or KFENCE - Rework printing of Spectre mitigation status to avoid hardlockup when enabling per-task mitigations on the context-switch path - Reject kernel modules when instruction patching fails either due to the DWARF-based SCS patching or because of an alternatives callback residing outside of the core kernel text - Propagate error when updating kernel memory permissions in kprobes - Drop pointless, incorrect message when enabling the ACPI SPCR console - Use value-returning LSE instructions for per-cpu atomics to reduce latency in SRCU locking routines" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Reject modules with internal alternative callbacks arm64: Fail module loading if dynamic SCS patching fails arm64: proton-pack: Fix hard lockup due to print in scheduler context arm64: proton-pack: Drop print when !CONFIG_MITIGATE_SPECTRE_BRANCH_HISTORY arm64: mm: Tidy up force_pte_mapping() arm64: mm: Optimize range_split_to_ptes() arm64: mm: Don't sleep in split_kernel_leaf_mapping() when in atomic context arm64: kprobes: check the return value of set_memory_rox() arm64: acpi: Drop message logging SPCR default console Revert "ACPI: Suppress misleading SPCR console message when SPCR table is absent" arm64: Use load LSE atomics for the non-return per-CPU atomic operations

2025-11-11mmc: omap: add WQ_PERCPU to alloc_workqueue usersMarco Crivellari
Currently if a user enqueues 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 consistency 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 continues the effort to refactor workqueue APIs, which began with the introduction of new workqueues and a new alloc_workqueue flag in: commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq") commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag") This change adds a new WQ_PERCPU flag to explicitly request alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified. 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.

2025-11-11mmc: mtk-sd: replace use of system_wq with system_percpu_wqMarco Crivellari
Currently if a user enqueues 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 consistency cannot be addressed without refactoring the API. 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") Replace system_wq with system_percpu_wq, keeping the same old behavior. The old wq (system_wq) will be kept for a few release cycles.

2025-11-11ALSA: usb-audio: Fix NULL pointer dereference in snd_usb_mixer_controls_baddHaein Lee
In snd_usb_create_streams(), for UAC version 3 devices, the Interface Association Descriptor (IAD) is retrieved via usb_ifnum_to_if(). If this call fails, a fallback routine attempts to obtain the IAD from the next interface and sets a BADD profile. However, snd_usb_mixer_controls_badd() assumes that the IAD retrieved from usb_ifnum_to_if() is always valid, without performing a NULL check. This can lead to a NULL pointer dereference when usb_ifnum_to_if() fails to find the interface descriptor. This patch adds a NULL pointer check after calling usb_ifnum_to_if() in snd_usb_mixer_controls_badd() to prevent the dereference. This issue was discovered by syzkaller, which triggered the bug by sending a crafted USB device descriptor.

2025-11-11reset: mpfs: add non-auxiliary bus probingConor Dooley
While the auxiliary bus was a nice bandaid, and meant that re-writing the representation of the clock regions in devicetree was not required, it has run its course. The "mss_top_sysreg" region that contains the clock and reset regions, also contains pinctrl and an interrupt controller, so the time has come rewrite the devicetree and probe the reset controller from an mfd devicetree node, rather than implement those drivers using the auxiliary bus. Wanting to avoid propagating this naive/incorrect description of the hardware to the new pic64gx SoC is a major motivating factor here.

This adds CQE support for the Rockchip RK3588 and RK3576 platform. To be functional, the eMMC device-tree node must have a 'supports-cqe;' flag property. As the RK3576 device-tree has been upstreamed with the 'supports-cqe;' property set by default, the kernel already tried to use CQE, which results in system hang during suspend. This fixes the issue.
