Pull SoC fixes from Arnd Bergmann: "The firmware drivers for ARM SCMI, FF-A and the Tee subsystem, as well as the reset controller and cache controller subsystem all see small bugfixes for reference ounting errors, ABI correctness, and NULL pointer dereferences. Similarly, there are multiple reference counting fixes in drivers/soc/ for vendor specific drivers (rockchips, microchip), while the freescale drivers get a fix for a race condition and error handling. The devicetree fixes for Rockchips and NXP got held up, so for the moment there is only Renesas fixing problesm with SD card initialization, a boot hang on one board and incorrect descriptions for interrupts and clock registers on some SoCs. The Microchip polarfire gets a dts fix for a boot time warning. A defconfig fix avoids a warning about a conflicting assignment" * tag 'soc-fixes-7.0' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (21 commits) ARM: multi_v7_defconfig: Drop duplicate CONFIG_TI_PRUSS=m firmware: arm_scmi: Spelling s/mulit/multi/, s/currenly/currently/ firmware: arm_scmi: Fix NULL dereference on notify error path firmware: arm_scpi: Fix device_node reference leak in probe path firmware: arm_ffa: Remove vm_id argument in ffa_rxtx_unmap() arm64: dts: renesas: r8a78000: Fix out-of-range SPI interrupt numbers arm64: dts: renesas: rzg3s-smarc-som: Set bypass for Versa3 PLL2 arm64: dts: renesas: r9a09g087: Fix CPG register region sizes arm64: dts: renesas: r9a09g077: Fix CPG register region sizes arm64: dts: renesas: r9a09g057: Remove wdt{0,2,3} nodes arm64: dts: renesas: rzv2-evk-cn15-sd: Add ramp delay for SD0 regulator arm64: dts: renesas: rzt2h-n2h-evk: Add ramp delay for SD0 card regulator tee: shm: Remove refcounting of kernel pages reset: rzg2l-usbphy-ctrl: Check pwrrdy is valid before using it soc: fsl: cpm1: qmc: Fix error check for devm_ioremap_resource() in qmc_qe_init_resources() soc: fsl: qbman: fix race condition in qman_destroy_fq soc: rockchip: grf: Add missing of_node_put() when returning cache: ax45mp: Fix device node reference leak in ax45mp_cache_init() cache: starfive: fix device node leak in starlink_cache_init() riscv: dts: microchip: add can resets to mpfs ...

ARM: multi_v7_defconfig: Drop duplicate CONFIG_TI_PRUSS=m

2026-03-14T11:34:25+00:00

Commit ee1ab82ee032 ("ARM: defconfig: move entries") added a duplicate instance of CONFIG_TI_PRUSS=m, causing a Kconfig warning: arch/arm/configs/multi_v7_defconfig:1152:warning: override: reassigning to symbol TI_PRUSS Drop the first instance, as the second instance added by the aforementioned change is where savedefconfig puts it.

kbuild: Split .modinfo out from ELF_DETAILS

2026-02-26T18:50:19+00:00

Commit 3e86e4d74c04 ("kbuild: keep .modinfo section in vmlinux.unstripped") added .modinfo to ELF_DETAILS while removing it from COMMON_DISCARDS, as it was needed in vmlinux.unstripped and ELF_DETAILS was present in all architecture specific vmlinux linker scripts. While this shuffle is fine for vmlinux, ELF_DETAILS and COMMON_DISCARDS may be used by other linker scripts, such as the s390 and x86 compressed boot images, which may not expect to have a .modinfo section. In certain circumstances, this could result in a bootloader failing to load the compressed kernel [1]. Commit ddc6cbef3ef1 ("s390/boot/vmlinux.lds.S: Ensure bzImage ends with SecureBoot trailer") recently addressed this for the s390 bzImage but the same bug remains for arm, parisc, and x86. The presence of .modinfo in the x86 bzImage was the root cause of the issue worked around with commit d50f21091358 ("kbuild: align modinfo section for Secureboot Authenticode EDK2 compat"). misc.c in arch/x86/boot/compressed includes lib/decompress_unzstd.c, which in turn includes lib/xxhash.c and its MODULE_LICENSE / MODULE_DESCRIPTION macros due to the STATIC definition. Split .modinfo out from ELF_DETAILS into its own macro and handle it in all vmlinux linker scripts. Discard .modinfo in the places where it was previously being discarded from being in COMMON_DISCARDS, as it has never been necessary in those uses.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

Convert 'alloc_flex' family to use the new default GFP_KERNEL argument

2026-02-22T01:09:51+00:00

This is the exact same thing as the 'alloc_obj()' version, only much smaller because there are a lot fewer users of the *alloc_flex() interface. As with alloc_obj() version, this was done entirely with mindless brute force, using the same script, except using 'flex' in the pattern rather than 'objs*'. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

ARM: clean up the memset64() C wrapper

2026-02-13T19:15:05+00:00

The current logic to split the 64-bit argument into its 32-bit halves is byte-order specific and a bit clunky. Use a union instead which is easier to read and works in all cases. GCC still generates the same machine code. While at it, rename the arguments of the __memset64() prototype to actually reflect their semantics.
