Pull sysctl updates from Joel Granados: - Remove "->procname == NULL" check when iterating through sysctl table arrays Removing sentinels in ctl_table arrays reduces the build time size and runtime memory consumed by ~64 bytes per array. With all ctl_table sentinels gone, the additional check for ->procname == NULL that worked in tandem with the ARRAY_SIZE to calculate the size of the ctl_table arrays is no longer needed and has been removed. The sysctl register functions now returns an error if a sentinel is used. - Preparation patches for sysctl constification Constifying ctl_table structs prevents the modification of proc_handler function pointers as they would reside in .rodata. The ctl_table arguments in sysctl utility functions are const qualified in preparation for a future treewide proc_handler argument constification commit. - Misc fixes Increase robustness of set_ownership by providing sane default ownership values in case the callee doesn't set them. Bound check proc_dou8vec_minmax to avoid loading buggy modules and give sysctl testing module a name to avoid compiler complaints. * tag 'sysctl-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl: sysctl: Warn on an empty procname element sysctl: Remove ctl_table sentinel code comments sysctl: Remove "child" sysctl code comments sysctl: Remove superfluous empty allocations from sysctl internals sysctl: Replace nr_entries with ctl_table_size in new_links sysctl: Remove check for sentinel element in ctl_table arrays mm profiling: Remove superfluous sentinel element from ctl_table locking: Remove superfluous sentinel element from kern_lockdep_table sysctl: Add module description to sysctl-testing sysctl: constify ctl_table arguments of utility function utsname: constify ctl_table arguments of utility function sysctl: move the extra1/2 boundary check of u8 to sysctl_check_table_array sysctl: always initialize i_uid/i_gid

Pull EFI updates from Ard Biesheuvel: "Note the removal of the EFI fake memory map support - this is believed to be unused and no longer worth supporting. However, we could easily bring it back if needed. With recent developments regarding confidential VMs and unaccepted memory, combined with kexec, creating a known inaccurate view of the firmware's memory map and handing it to the OS is a feature we can live without, hence the removal. Alternatively, I could imagine making this feature mutually exclusive with those confidential VM related features, but let's try simply removing it first. Summary: - Drop support for the 'fake' EFI memory map on x86 - Add an SMBIOS based tweak to the EFI stub instructing the firmware on x86 Macbook Pros to keep both GPUs enabled - Replace 0-sized array with flexible array in EFI memory attributes table handling - Drop redundant BSS clearing when booting via the native PE entrypoint on x86 - Avoid returning EFI_SUCCESS when aborting on an out-of-memory condition - Cosmetic tweak for arm64 KASLR loading logic" * tag 'efi-next-for-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi: efi: Replace efi_memory_attributes_table_t 0-sized array with flexible array efi: Rename efi_early_memdesc_ptr() to efi_memdesc_ptr() arm64/efistub: Clean up KASLR logic x86/efistub: Drop redundant clearing of BSS x86/efistub: Avoid returning EFI_SUCCESS on error x86/efistub: Call Apple set_os protocol on dual GPU Intel Macs x86/efistub: Enable SMBIOS protocol handling for x86 efistub/smbios: Simplify SMBIOS enumeration API x86/efi: Drop support for fake EFI memory maps

Pull SoC dt updates from Arnd Bergmann: "The devicetree updates are fairly well spread out across platforms, with Qualcomm making up about a third of the total. There are three new SoCs in existing product families this: - NXP i.MX95 is a variant of i.MX93, now with six Cortex-A55 cores instead of just two as well as a GPU and more high-speed I/O devices. - Qualcomm QCS8550 is a variant of SM8550 for IOT devices - Airoha EN7581 is a 10G-PON network chip and related to the MT7981 Wireless router chip from its parent Mediatek. In total there are 58 new machines, including four riscv boards and eight for 32-bit arm. The most exciting new addition is probably a pair of laptops based on the Qualcomm x1e80100 (Snapdragon X1 Elite) chip, the Asus Vivobook S15 and the Lenovo Yoga Slim7x. Other noteworthy new additions are: - A total of 20 Qualcomm based machines, mostly Android devices from Samsung, Motorola and LG, as well as a wireless router and some reference designs - Six NXP i.MX based machines, mostly industrial boards along with some reference designs - Mediatek sees some interesting Filogic based routers including the "OpenWRT One", a few new Chromebooks as well as single-board computers. - Four machines from Solidrun based on Marvell cn913x, replacing the older Armada 8000 based counterparts - The four Amlogic machines are all set top boxes or reference designs for them - The nine new Rockchips machines are mostly single-board computers including some interesting ones based on the rk3588 chip like the ROCK 5 ITX board and the CM3588 with its four NVMe slots - The RISC-V boards are all single-board computers based on Starfive JH7110, Microchip MPFS and Allwinner D1, which all had similar boards already There are also a lot of updates to already supported machines, notably for the TI K3, Rockchips, Freescale and of course Qualcomm platforms" * tag 'soc-dt-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (846 commits) arm64: dts: allwinner: h616: add crypto engine node riscv: dts: add clock generator for Sophgo SG2042 SoC arm64: dts: rockchip: Add Xunlong Orange Pi 3B dt-bindings: arm: rockchip: Add Xunlong Orange Pi 3B arm64: dts: rockchip: Add Radxa ROCK 3B dt-bindings: arm: rockchip: Add Radxa ROCK 3B mailmap: Update Luca Weiss's email address ARM: dts: ixp4xx: nslu2: beeper uses PWM arm64: dts: rockchip: add ROCK 5 ITX board dt-bindings: arm: rockchip: Add ROCK 5 ITX board arm64: dts: rockchip: Add dma-names to uart1 on Pine64 rk3566 devices arm64: dts: rockchip: Add avdd supplies to hdmi on rock64 arm64: dts: qcom: msm8916-lg-c50: add initial dts for LG Leon LTE arm64: dts: qcom: msm8916-lg-m216: Add initial device tree dt-bindings: arm: qcom: Add msm8916 based LG devices ARM: dts: qcom: msm8960: correct memory base arm64: dts: qcom: ipq9574: Add icc provider ability to gcc dt-bindings: interconnect: Add Qualcomm IPQ9574 support arm64: dts: qcom: sm8150: Add video clock controller node arm64: dts: qcom: pm6150: Add vibrator ...

Pull SoC driver updates from Arnd Bergmann: "The updates to the mediatek, allwinner, ti, tegra, microchip, stm32, samsung, imx, zynq and amlogic platoforms are fairly small maintenance changes, either addressing minor mistakes or enabling additional hardware. The qualcomm platform changes add a number of features and are larger than the other ones combined, introducing the use of linux/cleanup.h across several drivers, adding support for Snapdragon X1E and other SoCs in platform drivers, a new "protection domain mapper" driver, and a "shared memory bridge" driver. The cznic "turris omnia" router based on Marvell Armada gets a platform driver that talks to the board specific microcontroller. The reset and cache subsystems get a few minor updates to SoC specific drivers, while the ff-a, scmi and optee firmware drivers get some code refactoring and new features" * tag 'soc-drivers-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (122 commits) firmware: turris-mox-rwtm: Initialize completion before mailbox firmware: turris-mox-rwtm: Fix checking return value of wait_for_completion_timeout() firmware: turris-mox-rwtm: Do not complete if there are no waiters MAINTAINERS: drop riscv list from cache controllers platform: cznic: turris-omnia-mcu: fix Kconfig dependencies bus: sunxi-rsb: Constify struct regmap_bus soc: sunxi: sram: Constify struct regmap_config platform: cznic: turris-omnia-mcu: Depend on WATCHDOG platform: cznic: turris-omnia-mcu: Depend on OF soc: samsung: exynos-pmu: add support for PMU_ALIVE non atomic registers arm64: stm32: enable scmi regulator for stm32 firmware: qcom: tzmem: blacklist more platforms for SHM Bridge soc: qcom: wcnss: simplify with cleanup.h soc: qcom: pdr: simplify with cleanup.h soc: qcom: ocmem: simplify with cleanup.h soc: qcom: mdt_loader: simplify with cleanup.h soc: qcom: llcc: simplify with cleanup.h firmware: qcom: tzmem: simplify returning pointer without cleanup soc: qcom: socinfo: Add PM6350 PMIC arm64: dts: renesas: rz-smarc: Replace fixed regulator for USB VBUS ...

Pull x86 SEV updates from Borislav Petkov: - Add support for running the kernel in a SEV-SNP guest, over a Secure VM Service Module (SVSM). When running over a SVSM, different services can run at different protection levels, apart from the guest OS but still within the secure SNP environment. They can provide services to the guest, like a vTPM, for example. This series adds the required facilities to interface with such a SVSM module. - The usual fixlets, refactoring and cleanups [ And as always: "SEV" is AMD's "Secure Encrypted Virtualization".

Pull spi updates from Mark Brown: "There's some quite exciting core work in this release, we've got the beginnings of support for hardware initiated transfers which is itself independently useful for optimising fast paths in existing drivers. We also have a rework of the DMA mapping which allows finer grained decisions about DMA mapping messages and also helps remove some bodges that we'd had. Otherwise it's a fairly quiet release, a few new drivers and features for existing drivers, together with various cleanups and DT binding conversions. One regmap SPI fix made it's way in here too which I should probably have sent as a regmap fix instead. Summary: - Support for pre-optimising messages, reducing the overhead for messages that are repeatedly used (eg, reading the interrupt status from a device). This will also be used for hardware initiated transfers in future. - A reworking of how DMA mapping is done, introducing a new helper and allowing the DMA mapping decision to be done per transfer instead of per message. - Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A" * tag 'spi-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (72 commits) spi: dt-bindings: at91: Add sama7d65 compatible string spi: add ch341a usb2spi driver spi: dt-bindings: fsl-dspi: add compatible string 'fsl,lx2160a-dspi' spi: dt-bindings: fsl-dspi: add dmas and dma-names properties spi: spi: Remove unnecessary ‘0’ values from status spi: spi: Remove unnecessary ‘0’ values from rc spi: xcomm: fix coding style spi: xcomm: remove i2c_set_clientdata() spi: xcomm: make use of devm_spi_alloc_host() spi: xcomm: add gpiochip support spi: dt-bindings: snps,dw-apb-ssi.yaml: update compatible property spi: dt-bindings: fsl-dspi: Convert to yaml format spi: fsl-dspi: use common proptery 'spi-cs-setup(hold)-delay-ns' spi: axi-spi-engine: remove platform_set_drvdata() spi: spi-fsl-lpspi: Pass pm_ptr() spi: spi-imx: Pass pm_ptr() spi: spi-fsl-lpspi: Switch to SYSTEM_SLEEP_PM_OPS() spi: spi-imx: Switch to RUNTIME_PM_OPS/SYSTEM_SLEEP_PM_OPS() spi: add EXPORT_SYMBOL_GPL(devm_spi_optimize_message) spi: add devm_spi_optimize_message() helper ...

Merge tag 'pwrseq-updates-for-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull power sequencing updates from Bartosz Golaszewski: "This has been in development since last year's Linux Plumbers Conference and was inspired by the need to enable support upstream for Bluetooth/WLAN chips on Qualcomm platforms. The main problem we're fixing is powering up devices which are represented as separate objects in the kernel (binding to different drivers) but which share parts of the power-up sequence and thus need some kind of a mediator who knows the possible interactions and can assure they don't interfere with neither device's bring up. An example of such an inter-driver interaction is the WCN family of BT/WLAN chips from Qualcomm of which some models require the user to observe a certain delay between driving the bt-enable and wlan-enable GPIOs. This is not a new problem but up to this point all attempts at addressing it ended up hitting one wall or another and being dropped. The main obstacle was the fact that most these attempts tried to introduce the concept of a "power sequence" into the device-tree bindings which breaks the main DT rule: describe the hardware, not its behavior. The solution I proposed focuses on making the power sequencer drivers interpret the actual HW description flexibly. More details on that are in the linked cover letter. The second problem fixed here is powering up PCI devices before they are detected on the bus. This is achieved by creating special platform devices for device-tree nodes describing hard-wired PCI devices which bind to the so-called PCI power control drivers which enable required resources and trigger a bus rescan once the controlled device is up then setup the correct devlink hierarchy for power-management. By combining the two new frameworks we implemented the power sequencing PCI power control driver which is capable of powering up the WLAN modules of the QCom WCN family of chipsets. All this has spent a significant amount of time in linux-next and enabled WLAN/BT support on several Qualcomm platforms. To further prove that this is useful and needed: right after this was picked up into next, I was sent a series using the subsystem for a similar use-case on Amlogic platforms. This contains the core power sequencing framework, the first driver, PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and some fixes that came later" * tag 'pwrseq-updates-for-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: PCI/pwrctl: only call of_platform_populate() if CONFIG_OF is enabled power: sequencing: simplify returning pointer without cleanup PCI/pwrctl: Add a PCI power control driver for power sequenced devices PCI/pwrctl: Add PCI power control core code PCI/pwrctl: Create platform devices for child OF nodes of the port node PCI/pwrctl: Reuse the OF node for power controlled devices PCI: Hold the rescan mutex when scanning for the first time power: pwrseq: add a driver for the PMU module on the QCom WCN chipsets power: sequencing: implement the pwrseq core

Core: - Virtual CPU hotplug support for arm64 ACPI systems - cpufeature infrastructure cleanups and making the FEAT_ECBHB ID bits visible to guests - CPU errata: expand the speculative SSBS workaround to more CPUs - GICv3, use compile-time PMR values: optimise the way regular IRQs are masked/unmasked when GICv3 pseudo-NMIs are used, removing the need for a static key in fast paths by using a priority value chosen dynamically at boot time ACPI: - 'acpi=nospcr' option to disable SPCR as default console for arm64 - Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/ Perf updates: - Rework of the IMX PMU driver to enable support for I.MX95 - Enable support for tertiary match groups in the CMN PMU driver - Initial refactoring of the CPU PMU code to prepare for the fixed instruction counter introduced by Arm v9.4 - Add missing PMU driver MODULE_DESCRIPTION() strings - Hook up DT compatibles for recent CPU PMUs Kselftest updates: - Kernel mode NEON fp-stress - Cleanups, spelling mistakes Miscellaneous: - arm64 Documentation update with a minor clarification on TBI - Fix missing IPI statistics - Implement raw_smp_processor_id() using thread_info rather than a per-CPU variable (better code generation) - Make MTE checking of in-kernel asynchronous tag faults conditional on KASAN being enabled - Minor cleanups, typos" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (69 commits) selftests: arm64: tags: remove the result script selftests: arm64: tags_test: conform test to TAP output perf: add missing MODULE_DESCRIPTION() macros arm64: smp: Fix missing IPI statistics irqchip/gic-v3: Fix 'broken_rdists' unused warning when !SMP and !ACPI ACPI: Add acpi=nospcr to disable ACPI SPCR as default console on ARM64 Documentation: arm64: Update memory.rst for TBI arm64/cpufeature: Replace custom macros with fields from ID_AA64PFR0_EL1 KVM: arm64: Replace custom macros with fields from ID_AA64PFR0_EL1 perf: arm_pmuv3: Include asm/arm_pmuv3.h from linux/perf/arm_pmuv3.h perf: arm_v6/7_pmu: Drop non-DT probe support perf/arm: Move 32-bit PMU drivers to drivers/perf/ perf: arm_pmuv3: Drop unnecessary IS_ENABLED(CONFIG_ARM64) check perf: arm_pmuv3: Avoid assigning fixed cycle counter with threshold arm64: Kconfig: Fix dependencies to enable ACPI_HOTPLUG_CPU perf: imx_perf: add support for i.MX95 platform perf: imx_perf: fix counter start and config sequence perf: imx_perf: refactor driver for imx93 perf: imx_perf: let the driver manage the counter usage rather the user perf: imx_perf: add macro definitions for parsing config attr ...
