2025-04-10ARM: omap: pmic-cpcap: do not mess around without CPCAP or OMAP4Andreas Kemnade
The late init call just writes to omap4 registers as soon as CONFIG_MFD_CPCAP is enabled without checking whether the cpcap driver is actually there or the SoC is indeed an OMAP4. Rather do these things only with the right device combination. Fixes booting the BT200 with said configuration enabled and non-factory X-Loader and probably also some surprising behavior on other devices.

2025-04-07ARM: dts: Drop DTS for BCM59056 PMUArtur Weber
The BCM59056 PMU has its own separate DTSI, meant to be included in a DTS file after defining the pmu node on some I2C bus. This seems rather unintuitive; drop the DTS in favor of adding the BCM59056 PMU node directly into the device DTS files. If the amount of subdevices supported by the BCM590xx grows, and a common device tree turns out to be beneficial, it can be reintroduced in the future.

2025-04-07crypto: arm/chacha - remove the redundant skcipher algorithmsEric Biggers
Since crypto/chacha.c now registers chacha20-$(ARCH), xchacha20-$(ARCH), and xchacha12-$(ARCH) skcipher algorithms that use the architecture's ChaCha and HChaCha library functions, individual architectures no longer need to do the same. Therefore, remove the redundant skcipher algorithms and leave just the library functions. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-04-07crypto: chacha - centralize the skcipher wrappers for arch codeEric Biggers
Following the example of the crc32 and crc32c code, make the crypto subsystem register both generic and architecture-optimized chacha20, xchacha20, and xchacha12 skcipher algorithms, all implemented on top of the appropriate library functions. This eliminates the need for every architecture to implement the same skcipher glue code. To register the architecture-optimized skciphers only when architecture-optimized code is actually being used, add a function chacha_is_arch_optimized() and make each arch implement it. Change each architecture's ChaCha module_init function to arch_initcall so that the CPU feature detection is guaranteed to run before chacha_is_arch_optimized() gets called by crypto/chacha.c. In the case of s390, remove the CPU feature based module autoloading, which is no longer needed since the module just gets pulled in via function linkage.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - The series "Enable strict percpu address space checks" from Uros Bizjak uses x86 named address space qualifiers to provide compile-time checking of percpu area accesses. This has caused a small amount of fallout - two or three issues were reported. In all cases the calling code was found to be incorrect. - The series "Some cleanup for memcg" from Chen Ridong implements some relatively monir cleanups for the memcontrol code. - The series "mm: fixes for device-exclusive entries (hmm)" from David Hildenbrand fixes a boatload of issues which David found then using device-exclusive PTE entries when THP is enabled. More work is needed, but this makes thins better - our own HMM selftests now succeed. - The series "mm: zswap: remove z3fold and zbud" from Yosry Ahmed remove the z3fold and zbud implementations. They have been deprecated for half a year and nobody has complained. - The series "mm: further simplify VMA merge operation" from Lorenzo Stoakes implements numerous simplifications in this area. No runtime effects are anticipated. - The series "mm/madvise: remove redundant mmap_lock operations from process_madvise()" from SeongJae Park rationalizes the locking in the madvise() implementation. Performance gains of 20-25% were observed in one MADV_DONTNEED microbenchmark. - The series "Tiny cleanup and improvements about SWAP code" from Baoquan He contains a number of touchups to issues which Baoquan noticed when working on the swap code. - The series "mm: kmemleak: Usability improvements" from Catalin Marinas implements a couple of improvements to the kmemleak user-visible output. - The series "mm/damon/paddr: fix large folios access and schemes handling" from Usama Arif provides a couple of fixes for DAMON's handling of large folios. - The series "mm/damon/core: fix wrong and/or useless damos_walk() behaviors" from SeongJae Park fixes a few issues with the accuracy of kdamond's walking of DAMON regions. - The series "expose mapping wrprotect, fix fb_defio use" from Lorenzo Stoakes changes the interaction between framebuffer deferred-io and core MM. No functional changes are anticipated - this is preparatory work for the future removal of page structure fields. - The series "mm/damon: add support for hugepage_size DAMOS filter" from Usama Arif adds a DAMOS filter which permits the filtering by huge page sizes. - The series "mm: permit guard regions for file-backed/shmem mappings" from Lorenzo Stoakes extends the guard region feature from its present "anon mappings only" state. The feature now covers shmem and file-backed mappings. - The series "mm: batched unmap lazyfree large folios during reclamation" from Barry Song cleans up and speeds up the unmapping for pte-mapped large folios. - The series "reimplement per-vma lock as a refcount" from Suren Baghdasaryan puts the vm_lock back into the vma. Our reasons for pulling it out were largely bogus and that change made the code more messy. This patchset provides small (0-10%) improvements on one microbenchmark. - The series "Docs/mm/damon: misc DAMOS filters documentation fixes and improves" from SeongJae Park does some maintenance work on the DAMON docs. - The series "hugetlb/CMA improvements for large systems" from Frank van der Linden addresses a pile of issues which have been observed when using CMA on large machines. - The series "mm/damon: introduce DAMOS filter type for unmapped pages" from SeongJae Park enables users of DMAON/DAMOS to filter my the page's mapped/unmapped status. - The series "zsmalloc/zram: there be preemption" from Sergey Senozhatsky teaches zram to run its compression and decompression operations preemptibly. - The series "selftests/mm: Some cleanups from trying to run them" from Brendan Jackman fixes a pile of unrelated issues which Brendan encountered while runnimg our selftests. - The series "fs/proc/task_mmu: add guard region bit to pagemap" from Lorenzo Stoakes permits userspace to use /proc/pid/pagemap to determine whether a particular page is a guard page. - The series "mm, swap: remove swap slot cache" from Kairui Song removes the swap slot cache from the allocation path - it simply wasn't being effective. - The series "mm: cleanups for device-exclusive entries (hmm)" from David Hildenbrand implements a number of unrelated cleanups in this code. - The series "mm: Rework generic PTDUMP configs" from Anshuman Khandual implements a number of preparatoty cleanups to the GENERIC_PTDUMP Kconfig logic. - The series "mm/damon: auto-tune aggregation interval" from SeongJae Park implements a feedback-driven automatic tuning feature for DAMON's aggregation interval tuning. - The series "Fix lazy mmu mode" from Ryan Roberts fixes some issues in powerpc, sparc and x86 lazy MMU implementations. Ryan did this in preparation for implementing lazy mmu mode for arm64 to optimize vmalloc. - The series "mm/page_alloc: Some clarifications for migratetype fallback" from Brendan Jackman reworks some commentary to make the code easier to follow. - The series "page_counter cleanup and size reduction" from Shakeel Butt cleans up the page_counter code and fixes a size increase which we accidentally added late last year. - The series "Add a command line option that enables control of how many threads should be used to allocate huge pages" from Thomas Prescher does that.

Pull drm updates from Dave Airlie: "Outside of drm there are some rust patches from Danilo who maintains that area in here, and some pieces for drm header check tests. The major things in here are a new driver supporting the touchbar displays on M1/M2, the nova-core stub driver which is just the vehicle for adding rust abstractions and start developing a real driver inside of. xe adds support for SVM with a non-driver specific SVM core abstraction that will hopefully be useful for other drivers, along with support for shrinking for TTM devices.

The Arm Morello reference platform gets a devicetree for booting in normal aarch64 mode. The hardware supports experimental CHERI support, which requires a modified kernel. The AMD (formerly Xilinx) Versal NET SoC gets added, this is a combined FPGA with Cortex-A78 CPUs in a SoC. Six new ST STM32MP2 SoC variants are added. Like the earlier STM32MP25, the MP211, MP213, MP215, MP231, MP233 and MP235 models are based on one or two Cortex-A35 cores but each feature a different set of I/O devices. Mediatek MT8370 is a minor variation of MT8390 with fewer CPU and GPU cores Apple T2 is the baseboard management controller on earlier Intel CPU based Macs, with 16 models now gaining initial support. All the above come with dts files for the reference boards. In addition, these boards are added for the SoCs that are already supported: - The Milk-V Jupiter board based on SpacemiT K1/M1 - NetCube Systems Kumquat board based on the 32-bit Allwinner V3s SoC - Three boards based on 32-bit stm32mp1 - 11 distinct board variants from Toradex and one from Variscite, all based on i.MX6 - Google Pixel Pro 6 phone based on gs101 (Tensor) - Three additional variants of the i.MX8MP based "Skov" board - A second variant of the i.MX95 EVK board - Two boards based on Renesas SoCs - Four boards based the Rockchip RK35xx series, plus the RK3588 'MNT Reform 2' laptop" * tag 'soc-dt-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (538 commits) arm64: dts: Add gpio_intc node for Amlogic A5 SoCs arm64: dts: Add gpio_intc node for Amlogic A4 SoCs arm64: dts: hi3660: Add property for fixing CPUIdle arm64: dts: rockchip: remove ethm0_clk0_25m_out from Sige5 gmac0 arm64: dts: marvell: Use preferred node names for "simple-bus" arm64: dts: marvell: Drop unused CP11X_TYPE define arm64: dts: marvell: Move arch timer and pmu nodes to top-level arm64: dts: rockchip: Fix PWM pinctrl names arm64: dts: rockchip: fix RK3576 SCMI clock IDs dt-bindings: clock: rk3576: add SCMI clocks arm64: dts: rockchip: Fix pcie reset gpio on Orange Pi 5 Max arm64: dts: amd/seattle: Drop undocumented "spi-controller" properties arm64: dts: amd/seattle: Fix bus, mmc, and ethernet node names arm64: dts: amd/seattle: Move and simplify fixed clocks arm64: dts: amd/seattle: Base Overdrive B1 on top of B0 version arm64: dts: rockchip: Enable HDMI audio output for ArmSoM Sige7 arm64: dts: rockchip: Enable onboard eMMC on Radxa E20C arm64: dts: rockchip: Add SDHCI controller for RK3528 arm64: dts: rockchip: Remove bluetooth node from rock-3a arm64: dts: rockchip: Move rk356x scmi SHMEM to reserved memory ...

As a driver opt-in protect queue operations and (in due course) ethtool operations with the instance lock and not RTNL lock. - Support collecting TCP timestamps (data submitted, sent, acked) in BPF, allowing for transparent (to the application) and lower overhead tracking of TCP RPC performance. - Tweak existing networking Rx zero-copy infra to support zero-copy Rx via io_uring. - Optimize MPTCP performance in single subflow mode by 29%. - Enable GRO on packets which went thru XDP CPU redirect (were queued for processing on a different CPU). Improving TCP stream performance up to 2x. - Improve performance of contended connect() by 200% by searching for an available 4-tuple under RCU rather than a spin lock. Bring an additional 229% improvement by tweaking hash distribution. - Avoid unconditionally touching sk_tsflags on RX, improving performance under UDP flood by as much as 10%. - Avoid skb_clone() dance in ping_rcv() to improve performance under ping flood. - Avoid FIB lookup in netfilter if socket is available, 20% perf win. - Rework network device creation (in-kernel) API to more clearly identify network namespaces and their roles. There are up to 4 namespace roles but we used to have just 2 netns pointer arguments, interpreted differently based on context. - Use sysfs_break_active_protection() instead of trylock to avoid deadlocks between unregistering objects and sysfs access. - Add a new sysctl and sockopt for capping max retransmit timeout in TCP. - Support masking port and DSCP in routing rule matches. - Support dumping IPv4 multicast addresses with RTM_GETMULTICAST. - Support specifying at what time packet should be sent on AF_XDP sockets. - Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users. - Add Netlink YAML spec for WiFi (nl80211) and conntrack. - Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols which only need to be exported when IPv6 support is built as a module. - Age FDB entries based on Rx not Tx traffic in VxLAN, similar to normal bridging. - Allow users to specify source port range for GENEVE tunnels. - netconsole: allow attaching kernel release, CPU ID and task name to messages as metadata Driver API: - Continue rework / fixing of Energy Efficient Ethernet (EEE) across the SW layers. Delegate the responsibilities to phylink where possible. Improve its handling in phylib. - Support symmetric OR-XOR RSS hashing algorithm. - Support tracking and preserving IRQ affinity by NAPI itself. - Support loopback mode speed selection for interface selftests.

2025-03-26ARM: 9444/1: add KEEP() keyword to ARM_VECTORSChristian Eggers
Without this, the vectors are removed if LD_DEAD_CODE_DATA_ELIMINATION is enabled. At startup, the CPU (silently) hangs in the undefined instruction exception as soon as the first timer interrupt arrives. On my setup, the system also boots fine without the 2nd and 3rd KEEP() statements, so I cannot tell whether these are actually required.

2025-03-26ARM: 9443/1: Require linker to support KEEP within OVERLAY for DCENathan Chancellor
ld.lld prior to 21.0.0 does not support using the KEEP keyword within an overlay description, which may be needed to avoid discarding necessary sections within an overlay with '--gc-sections', which can be enabled for the kernel via CONFIG_LD_DEAD_CODE_DATA_ELIMINATION. Disallow CONFIG_LD_DEAD_CODE_DATA_ELIMINATION without support for KEEP within OVERLAY and introduce a macro, OVERLAY_KEEP, that can be used to conditionally add KEEP when it is properly supported to avoid breaking old versions of ld.lld.

2025-03-26ARM: 9442/1: smp: Fix IPI alignment in /proc/interruptsGeert Uytterhoeven
On a system with less than 1000 interrupts, prec = 3, causing a misalignment for the IPI interrupts. E.g. on Koelsch (R-Car M2-W): 200: 0 0 gpio-rcar 6 Edge SW36 IPI0: 0 0 CPU wakeup interrupts IPI1: 0 0 Timer broadcast interrupts IPI2: 1701 2844 Rescheduling interrupts IPI3: 10338 21181 Function call interrupts IPI4: 0 0 CPU stop interrupts IPI5: 651 825 IRQ work interrupts IPI6: 0 0 completion interrupts Err: 0 Fix this by adopting the same solution as used on arm64.
