Probes for v6.18:
- fprobe: Performance enhancement of the fprobe using rhltable
. fprobe: use rhltable for fprobe_ip_table. The fprobe IP table has
been converted to use an rhltable for improved performance when
dealing with a large number of probed functions.
. Fix a suspicious RCU usage warning of the above change in the
fprobe entry handler.
. Remove an unused local variable of the above change.
. Fix to initialize fprobe_ip_table in core_initcall().
- wprobe: Introduce a watchpoint probe event based on hw_breakpoint.
. Add a new watchpoint probe that uses hardware breakpoints to
monitor memory accesses. This allows for tracing memory reads
and writes at specified addresses.
. Add a basic add/remove test case for wprobe.
. Add a syntax test case for wprobe.
- probes: Cleanup probe event subsystems.
. uprobe/eprobe: Allocate traceprobe_parse_context per probe instead
of each probe argument parsing. This reduce memory allocation/free
of temporary working memory.
. uprobes: Cleanup code using __free().
. eprobes: Cleanup code using __free().
. probes: Cleanup code using __free(trace_probe_log_clear) to clear
error log automatically.
. probes: Replace strcpy() with memcpy() in __trace_probe_log_err().
probes-v6.18-2
development cycle. No merge conflicts are present and none are anticipated. Thanks. Patch series in this pull request: - The 3 patch series "ida: Remove the ida_simple_xxx() API" from Christophe Jaillet completes the removal of this legacy IDR API. - The 9 patch series "panic: introduce panic status function family" from Jinchao Wang provides a number of cleanups to the panic code and its various helpers, which were rather ad-hoc and scattered all over the place. - The 5 patch series "tools/delaytop: implement real-time keyboard interaction support" from Fan Yu adds a few nice user-facing usability changes to the delaytop monitoring tool. - The 3 patch series "efi: Fix EFI boot with kexec handover (KHO)" from Evangelos Petrongonas fixes a panic which was happening with the combination of EFI and KHO. - The 2 patch series "Squashfs: performance improvement and a sanity check" from Phillip Lougher teaches squashfs's lseek() about SEEK_DATA/SEEK_HOLE. A mere 150x speedup was measured for a well-chosen microbenchmark. - Plus another 50-odd singleton patches all over the place.
RCU pull request for v6.18
This pull request contains the following branches, non-octopus merged:
Documentation updates:
- Update whatisRCU.rst and checklist.rst for recent RCU API additions.
- Fix RCU documentation formatting and typos.
- Replace dead Ottawa Linux Symposium links in RTFP.txt.
Miscellaneous RCU updates:
- Document that rcu_barrier() hurries RCU_LAZY callbacks.
- Remove redundant interrupt disabling from
rcu_preempt_deferred_qs_handler().
- Move list_for_each_rcu from list.h to rculist.h, and adjust the
include directive in kernel/cgroup/dmem.c accordingly.
- Make initial set of changes to accommodate upcoming system_percpu_wq
changes.
SRCU updates:
- Create an srcu_read_lock_fast_notrace() for eventual use in tracing,
including adding guards.
- Document the reliance on per-CPU operations as implicit RCU readers
in __srcu_read_{,un}lock_fast().
- Document the srcu_flip() function's memory-barrier D's relationship
to SRCU-fast readers.
- Remove a redundant preempt_disable() and preempt_enable() pair from
srcu_gp_start_if_needed().
Torture-test updates:
- Fix jitter.sh spin time so that it actually varies as advertised.
It is still quite coarse-grained, but at least it does now vary.
- Update torture.sh help text to include the not-so-new --do-normal
parameter, which permits (for example) testing KCSAN kernels without
doing non-debug kernels.
- Fix a number of false-positive diagnostics that were being triggered
by rcutorture starting before boot completed. Running multiple
near-CPU-bound rcutorture processes when there is only the boot CPU
is after all a bit excessive.
- Substitute kcalloc() for kzalloc().
- Remove a redundant kfree() and NULL out kfree()ed objects.
rpmsg updates for v6.18 Clean up the dev_pm_domain integration in rpmsg core. Correct module aliases for the rpmsg char driver. Transition Qualcomm SMD and GLINK drivers to strscpy() and fix the regression in legacy code for acquiring outgoing interrupts using the non-mailbox based mechanism.
remoteproc updates for v6.18 Enable coredump support for the i.MX HiFi core remoteproc, and clean up the i.MX remoteproc driver. Introduce remoteprocs on the Qualcomm Milos platform. Gracefully shut own the ADSP remoteproc when bootloader has loaded the "Lite" firmware on X Elite. Improve the resource handover procedure to avoid possibly duplicate handling. Transition the TI DA8xx, TI Keystone, and TI Wakeup M3 remoteproc drivers to handle resources using devres.
please pull the latest printk changes from - Add KUnit test for the printk ring buffer. - Fix the check of the maximal record size which is allowed to be stored into the printk ring buffer. It prevents corruptions of the ring buffer. Note that printk() is on the safe side. The messages are limited by 1kB buffer and are always small enough for the minimal log buffer size 4kB, see CONFIG_LOG_BUF_SHIFT definition.
IOMMU Updates for Linux v6.18: Including: - Inte VT-d: - IOMMU driver updated to the latest VT-d specification. - Don't enable PRS if PDS isn't supported. - Replace snprintf with scnprintf. - Fix legacy mode page table dump through debugfs. - Miscellaneous cleanups. - AMD-Vi: - Support kdump boot when SNP is enabled. - Apple-DART: - 4-level page-table support. - RISC-V IOMMU: - ACPI support. - Small number of miscellaneous cleanups and fixes.

This patchset concentrates upon clearing up the treatment of stacked filesystems. - The 6 patch series "mm: Improve mlock tracking for large folios" from Kiryl Shutsemau provides some fixes and improvements to mlock's tracking of large folios. /proc/meminfo's "Mlocked" field became more accurate. - The 2 patch series "mm/ksm: Fix incorrect accounting of KSM counters during fork" from Donet Tom fixes several user-visible KSM stats inaccuracies across forks and adds selftest code to verify these counters. - The 2 patch series "mm_slot: fix the usage of mm_slot_entry" from Wei Yang addresses some potential but presently benign issues in KSM's mm_slot handling.
asm-generic: updates for 6.18 Two small patches for the asm-generic header files: Varad Gautam improves the MMIO tracing to be faster when the tracepoints are built into the kernel but disabled, while Qi Xi updates the DO_ONCE logic so that clearing the WARN_ONCE() flags does not change the other DO_ONCE users.
These are the SoC updates for the 6.18 release on Arm and RISC-V
platforms. With about 1150 non-merge changesets and 70000 lines
added, this is one of the larger sets recently, and a lot of
that comes from updates for the Qualcomm, NXP/Freescale and Apple
platforms, which have both a significant number of new machines
and other updates.
There is one new RISC-V chip family in a separate branch, plus
new SoCs in five existing families.

Here is the i3c subsystem pull request for 6.18. Another controller driver has been added this cycle. We also have many improvements for the mipi-i3c-hci driver. I3C for 6.18 New driver: - Analog Devices I3C Controller Subsystem: - fix big-endian FIFO transfers - fix default I2C adapter timeout value Drivers: - dw: shutdown support - mipi-i3c-hci: Intel Wildcat Lake-U support, IOMMU support - renesas: RZ/V2H(P) and RZ/V2N support
Please a pair of x86/entry changes for 6.18-rc1. The FRED one adjusts the kernel to the latest spec. The spec change prevents attackers from abusing kernel entry points. The second one came about because of the LASS work[1]. It moves the vsyscall emulation code away from depending on X86_PF_INSTR which is not available on some CPUs. Those CPUs are pretty obscure these days, but this still seems like the right thing to do. It also makes this code consistent with some things that the LASS code is going to do. 1. https://lore.kernel.org/lkml/20250620135325.3300848-1-kirill.shutemov@linux.intel.com/ -- - Use RIP instead of X86_PF_INSTR for vsyscall emulation - Remove ENDBR64 from FRED entry points
is making TDX and kexec play nicely together. Before this, the memory encryption hardware (which doesn't respect cache coherency) could write back old cachelines on top of data in the new kernel, so kexec and TDX were made mutually exclusive. This removes the limitation. There is also some work to tighten up a hardware bug workaround and some MAINTAINERS updates. -- - Make TDX and kexec work together - Skip TDX bug workaround when the bug is not present - Update maintainers entries
Riel's work to get the INVLPGB instruction working. It just removes an open-coded TLB flush operation by using an existing helper. -- Change cpa_flush() to call flush_kernel_range() directly

Backlight for v6.18 This set is comprised of a couple of small but important fixes and a number of clean-up and refactoring patches. The fixes correct an EPROM address for the LP8556 and improve memory allocation safety in the LED backlight driver. The remainder of the set is made up of refactoring work to the mp3309c driver and a series of patches to make a number of drivers more self-contained by including their own dependencies. Improvements & Fixes - Correct the EPROM start address for the LP8556 to align with the device's datasheet. - Use devm_kcalloc() in the LED backlight driver for safer array allocation with overflow protection. Cleanups & Refactoring - Drop an unnecessary call to pwm_apply_args() in the mp3309c driver. - Modernize struct initialization in the mp3309c driver by using a compound literal instead of memset. - Make numerous drivers self-contained by including necessary headers directly rather than relying on transitive includes from the core backlight header.
LEDs for v6.18 This submission is a mix of new features, a number of fixes, some clean-up/refactoring and a few Device Tree binding updates. The most significant changes include new device support for the IS31FL3236A and QNAP's status LEDs, a number of fixes for the Qualcomm flash, LP55xx, MAX77705 and QNAP MCU drivers, along with some generic LED consumer binding documentation and unification. New Support & Features - Add support for the IS31FL3236A LED driver, including an optional 22kHz PWM frequency setting. - Add support for the red and green status LEDs on QNAP MCU devices. Improvements & Fixes - Fix an issue in the MAX77705 driver where an error value was assigned but not returned. - Correctly update the torch current clamp setting in the Qualcomm flash LED driver to prevent unexpected clamping. - Add a separate register map for the PMI8998 to the Qualcomm flash LED driver to handle its unique register layout. - Fix the state numbering for the USB LED in the QNAP MCU driver to avoid command conflicts. - Correct the memory programming address calculation for non-paged devices like the LP5562 in the LP55xx driver. - Add Device Tree support to the generic led_get() function, allowing LEDs to be looked up by name. Cleanups & Refactoring - Fix a spelling mistake in the Kconfig help text for the BD2606MVV driver. - Use devm_mutex_init() in the IS31FL319x driver to simplify code. Device Tree Bindings Updates - Drop the redundant '-db' suffix from the IS31FL319x binding. - Introduce generic LED consumer bindings for referencing LEDs via phandles. - Unify the 'leds' property across several bindings to use the new generic consumer binding. - Convert the AMS AS3645A LED controller binding to the DT schema format.
MFD for v6.18 This round of updates contains a fair amount of new device support, a couple of fixes and some refactoring. The most notable additions include new drivers for Loongson's Security Engine, RNG and TPM, new drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs. The rest of the set provides a return value check fix and a refactoring to use a more modern GPIO API for the VEXPRESS sysreg driver, the removal of a deprecated IRQ ACK function from the MC13xxx RTC driver and a new DT binding for the aforementioned TI BQ257xx charger. New Support & Features - Add a suite of drivers for the Loongson Security Engine, including the core controller, a Random Number Generator (RNG) and Trusted Platform Module (TPM) support. - Introduce support for the TI TPS6594 PMIC's power button, including the input driver, MFD cell registration, and a system power-off handler. - Add comprehensive support for the TI BQ257xx series of charger ICs, including the core MFD driver and a power supply driver for the charger functionality. Improvements & Fixes - Check the return value of devm_gpiochip_add_data() in the VEXPRESS sysreg driver to prevent potential silent failures. Cleanups & Refactoring - Add a MAINTAINERS entry for the new Loongson Security Engine drivers. - Convert the VEXPRESS sysreg driver to use the modern generic GPIO chip API. Removals - Remove the deprecated and unused mc13xxx_irq_ack() function from the MC13xxx RTC, input and touchscreen drivers. Device Tree Bindings Updates - Add device tree bindings for the TI BQ25703A charger.

Networking changes for 6.18.
Core & protocols
Here are the changes for configfs for v6.18. This time it is just a very small refactoring to use PTR_ERR_OR_ZERO(). Best regards, Andreas Hindborg configfs changes for v6.18
This is the main drm pull request for the 6.18 merge window. Compared to last time there are only 2 xe merge conflicts when I merged this into your tree this morning. One of them is simple, the other a bit tricky, as all the goto cleanup should be return ret, not sure where they get lost. Let me know if you have any problems, but taking what is in next should be fine. Outside the drm tree, there are i2c-hid changes and an MEI driver addition. The other big thing here is rust stuff. There is a pin-init rework which may also be merged in other trees (I can't remember). Then dma, device and drm stuff. This also has updates to the nova-core, nova-drm drivers and introduces a skeleton driver Tyr for ARM Mali, which will be constructed upstream as the rust pieces are merged. Other highlights: - rocket accel driver for Rockchip NPUs - habanalabs upstreaming has restarted - xe support for madvise in gpusvm - amdgpu CRIU support for gem objects Then there is the usual insane number of patches to everything across the b= oard. As usual, let me know if there are any problems.

this is the big pull request with v6.18 pin control changes. Most of the details are in the signed tag, we have GPIO awareness in the pin control core and an interesting AAEON driver. At rc6 you expressed strongly that you don't want to see unsolicited Link: tags unless these provide some additional information that is actually useful for regressions and debugging, so at this point I dropped the automated addition of Link: tags. They are still present on prior commits, I hope that is OK for now. They will not be in future pull requests. Some GPIO and Renesas cross-tree changes are coming into the diffstat through immutable branches that I pulled in, including some string helper lib functions and what not. Yours, Linus Walleij Pin control changes for the v6.18 kernel cycle: Core changes: - Allow pins to be identified/marked as GPIO mode with a special callback. The pin controller core is now "aware" if a pin is in GPIO mode if the callback is implemented in the driver, and can thus be marked as "strict", i.e. disallowing simultaneous use of a line as GPIO and another function such as I2C. This is enabled in the Qualcomm TLMM driver and also implemeted from day 1 in the new Broadcom STB driver. - Rename the pin config option PIN_CONFIG_OUTPUT to PIN_CONFIG_LEVEL to better describe what the config is doing, as well as making it more intuitive what shall be returned when reading this property. New drivers: - Qualcomm SDM660 LPASS LPI TLMM pin controller subdriver. - Qualcomm Glymur family pin controller driver. - Broadcom STB family pin controller driver. - Tegra186 pin controller driver. - AAEON UP pin controller support. This is some special pin controller that works as an external advanced line MUX and amplifier for signals from an Intel SoC. A cooperative effort with the GPIO maintainer was needed to reach a solution where we reuse code from the GPIO aggregator/forwarder driver. - Renesas RZ/T2H and RZ/N2H pin controller support. - Axis ARTPEC-8 subdriver for the Samsung pin controller driver. Improvements: - Output enable (OEN) support in the Renesas RZG2L driver. - Properly support bias pull up/down in the pinctrl-single driver. - Move over all GPIO portions using generic MMIO GPIO to the new generic GPIO chip management which has a nice and separate API. - Proper DT bindings for some older Broadcom SoCs. - External GPIO (EGPIO) support in the Qualcomm SM8250. Deleted code: - Dropped the now unused Samsung S3C24xx drivers.
VFIO updates for v6.18-rc1 - Use fdinfo to expose the sysfs path of a device represented by a vfio device file. (Alex Mastro) - Mark vfio-fsl-mc, vfio-amba, and the reset functions for vfio-platform for removal as these are either orphaned or believed to be unused. (Alex Williamson) - Add reviewers for vfio-platform to save it from also being marked for removal. (Mostafa Saleh, Pranjal Shrivastava) - VFIO selftests, including basic sanity testing and minimal userspace drivers for testing against real hardware. This is also expected to provide integration with KVM selftests for KVM-VFIO interfaces. (David Matlack, Josh Hilke) - Fix drivers/cdx and vfio/cdx to build without CONFIG_GENERIC_MSI_IRQ. (Nipun Gupta) - Fix reference leak in hisi_acc. (Miaoqian Lin) - Use consistent return for unsupported device feature. (Alex Mastro) - Unwind using the correct memory free callback in vfio/pds. (Zilin Guan) - Use IRQ_DISABLE_LAZY flag to improve handling of pre-PCI2.3 INTx and resolve stalled interrupt on ppc64. (Timothy Pearson) - Enable GB300 in nvgrace-gpu vfio-pci variant driver. (Tushar Dave) - Misc: - Drop unnecessary ternary conversion in vfio/pci. (Xichao Zhao) - Grammatical fix in nvgrace-gpu. (Morduan Zang) - Update Shameer's email address. (Shameer Kolothum) - Fix document build warning. (Alex Williamson)

please pull sound updates for v6.18-rc1 from: The topmost commit is f65dc3b1ab145c9b8b36301256d703c1dd153f71 sound updates for 6.18-rc1 It's been relatively calm in this cycle from the feature POV, but there were lots of cleanup works in the wide-range of code for converting with the auto-cleanup macros like guard(). The mostly user-visible changes are the support of a couple of new compress-offload API extensions, and the support of new ASoC codec / platform drivers as well as USB-audio quirks. Here we go with some highlights: Core: - Compress-offload API extension for 64bit timestamp support - Compress-offload API extension for OPUS codec support - Workaround for PCM locking issue with PREEMPT_RT and softirq - KCSAN warning fix for ALSA sequencer core ASoC: - Continued cleanup works for ASoC core APIs - Lots of cleanups and conversions of DT bindings - Substantial maintainance work on the Intel AVS drivers - Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai FourSemi FS2104/5S, Texas Instruments PCM1754 and TAS2783A - Remove support for TI WL1273 for old Nokia systems USB-audio: - Support for Tascam US-144mkII, Presonus S1824c support - More flexible quirk option handling - Fix for USB MIDI timer bug triggered by fuzzer Others: - A large series of cleanups with guard() & co macros over (non-ASoC) sound drivers (PCI, ISA, HD-audio, USB-audio, drivers, etc) - TAS5825 HD-audio side-codec support
It has been a relatively busy cycle in docsland, with changes all over: - Bring the kernel memory-model docs into the Sphinx build in the "literal include" mode. - Lots of build-infrastructure work, further cleaning up long-term kernel-doc technical debt. The sphinx-pre-install tool has been converted to Python and updated for current systems. - A new tool to detect when documents have been moved and generate HTML redirects; this can be used on kernel.org (or any other site hosting the rendered docs) to avoid breaking links. - Automated processing of the YAML files describing the netlink protocol. - A significant update of the maintainer's PGP guide. ...and a seemingly endless series of typo fixes, build-problem fixes, etc.
Here is the main PDx86 PR for v6.18.
There's one-liner change into sound/ due to x86-android-tables moving away
from using GPIO legacy APIs which changes the name of a SPI/codec device.

dma-mapping updates for Linux 6.18: - refactoring of DMA mapping API to physical addresses as the primary interface instead of page+offset parameters; this gets much closer to Matthew Wilcox's long term wish for struct-pageless IO to cacheable DRAM and is supporting memdesc project which seeks to substantially transform how struct page works; an advantage of this approach is the possibility of introducing DMA_ATTR_MMIO, which covers existing 'dma_map_resource' flow in the common paths, what in turn lets to use recently introduced dma_iova_link() API to map PCI P2P MMIO without creating struct page; developped by Leon Romanovsky and Jason Gunthorpe - minor clean-up by Petr Tesarik and Qianfeng Rong
This update includes the following changes: Drivers: - Add ciphertext hiding support to ccp. - Add hashjoin, gather and UDMA data move features to hisilicon. - Add lz4 and lz77_only to hisilicon. - Add xilinx hwrng driver. - Add ti driver with ecb/cbc aes support. - Add ring buffer idle and command queue telemetry for GEN6 in qat. Others: - Use rcu_dereference_all to stop false alarms in rhashtable. - Fix CPU number wraparound in padata.
This branch has been sitting in linux-next for a few weeks, but I added some RVB last week. It has gone through the usual overlayfs test routines. The branch merges cleanly with master branch of the moment. Note that there is a small change to fs.h in this PR for the sb encoding helpers. This change is reviewed by Gabriel and Christian has agreed that I will merge it through the ovl tree. Thanks, Amir. overlayfs updates for 6.18 - Work by André Almeida to support case-insensitive overlayfs Underlying case-insensitive filesystems casefolding is per directory, but for overlayfs it is all-or-nothing. It supports layers where all directories are casefolded (with same encoding) or layers where no directories are casefolded. - A fix for a "bug" in Neil's ovl directory lock changes, which only manifested itself with casefold enabled layers which may return an unhashed negative dentry from lookup.
please pull the latest slab updates from: This time we have two rather large features - a new percpu caching scheme and re-entrant kmalloc_nolock(), along with the usual fixes and cleanups. To avoid conflicts with mm tree, the patches from Lorenzo and Qianfeng are part of this pull although normally they would be in mm tree. There should be no conflicts. Thanks, Vlastimil * A new layer for caching objects for allocation and free via percpu arrays called sheaves. The aim is to combine the good parts of SLAB (lower-overhead and simpler percpu caching, compared to SLUB) without the past issues with arrays for freeing remote NUMA node objects and their flushing. It also allows more efficient kfree_rcu(), and cheaper object preallocations for cases where the exact number of objects is unknown, but an upper bound is. Currently VMAs and maple nodes are using this new caching, with a plan to enable it for all caches and remove the complex SLUB fastpath based on cpu (partial) slabs and this_cpu_cmpxchg_double(). (Vlastimil Babka, with Liam Howlett and Pedro Falcato for the maple tree changes) * Re-entrant kmalloc_nolock(), which allows opportunistic allocations from NMI and tracing/kprobe contexts. Building on prior page allocator and memcg changes, it will result in removing BPF-specific caches on top of slab. (Alexei Starovoitov) * Various fixes and cleanups. (Kuan-Wei Chiu, Matthew Wilcox, Suren Baghdasaryan, Ye Liu)
request, so if I have done something incorrect or unsatisfactory to
your standards, please let me know so I (and Nicolas) can avoid
repeating mistakes in the future.
The majority of these changes have been in -next for several cycles
with no reported problems. I am only aware of one conflict with the
arm64 tree around CONFIG_CPU_BIG_ENDIAN, Mark's resolution looks
correct to me.
https://lore.kernel.org/aNU-sG84vqPj7p7G@sirena.org.uk/
There are several changes from other areas (mostly architectures) that
should have their appropriate acks and such.
There is a back merge of 6.17-rc6, which should have sufficient
justification but I know back merges can be contentious so I figured
I would be open with it up front anyways. Looking back on it, I probably
should have only merged up to 6.17-rc4 for commit bd7c2312128e ("pinctrl:
meson: Fix typo in device table macro") but I went with -rc6 to try and
head off a simple conflict from commit 41f9049cff32 ("riscv: Only allow
LTO with CMODEL_MEDANY") in -rc5. In the end, it didn't matter because
of the arm64 conflict so I will be more careful in the future.
Cheers,
Nathan
Kbuild updates for 6.18
- Extend modules.builtin.modinfo to include module aliases from
MODULE_DEVICE_TABLE for builtin modules so that userspace tools (such
as kmod) can verify that a particular module alias will be handled by
a builtin module.
- Bump the minimum version of LLVM for building the kernel to 15.0.0.
- Upgrade several userspace API checks in headers_check.pl to errors.
- Unify and consolidate CONFIG_WERROR / W=e handling.
- Turn assembler and linker warnings into errors with CONFIG_WERROR /
W=e.
- Respect CONFIG_WERROR / W=e when building userspace programs
(userprogs).
- Enable -Werror unconditionally when building host programs
(hostprogs).
- Support copy_file_range() and data segment alignment in gen_init_cpio
to improve performance on filesystems that support reflinks such as
btrfs and XFS.
- Miscellaneous small changes to scripts and configuration files.

Hi Linus,
A seven patch series adds a new parameterized test features
KUnit parameterized tests currently support two primary methods for
getting parameters:
1. Defining custom logic within a generate_params() function.
2. Using the KUNIT_ARRAY_PARAM() and KUNIT_ARRAY_PARAM_DESC()
macros with a pre-defined static array and passing
the created *_gen_params() to KUNIT_CASE_PARAM().
These methods present limitations when dealing with dynamically
generated parameter arrays, or in scenarios where populating parameters
sequentially via generate_params() is inefficient or overly complex.
These limitations are fixed with a parameterized test method.
- Fixes issues in kunit build artifacts cleanup,
- Fixes parsing skipped test problem in kselftest framework,
- Enables PCI on UML without triggering WARN()
- a few other fixes and adds support for new configs such as MIPS
diff is attached.
thanks,

is the creation of the "transitional" keyword for kconfig so CONFIG renaming can go more smoothly. This has been a long-standing deficiency, and with the renaming of CONFIG_CFI_CLANG to CONFIG_CFI (since GCC will soon have KCFI support), this came up again. The breadth of the diffstat is mainly this renaming. Thanks! -Kees hardening updates for v6.18-rc1 - Clean up usage of TRAILING_OVERLAP() (Gustavo A. R.

working on various hardening refactoring a while back we encountered inconsistencies in the application of __attribute_const__ on the ffs() family of functions. This series fixes this across all archs and adds KUnit tests. Notably, this found a theoretical underflow in PCI (also fixed here) and uncovered an inefficiency in ARC (fixed in the ARC arch PR). I kept the series separate from the general hardening PR since it is a stand-alone "topic". Thanks! -Kees ffs-const update for v6.18-rc1 - PCI: Fix theoretical underflow in use of ffs(). - Universally apply __attribute_const__ to all architecture's ffs()-family of functions. - Add KUnit tests for ffs() behavior and const-ness.

Please accept the changes for FireWire subsystem to your tree. This update may appear to include many changes, but most of them are code refactoring. Except for the removal of firewire-ohci module parameter, there are only a few notable changes. firewire updates for v6.18 This update includes the following changes: - Removal of the deprecated debug parameter from firewire-ohci module - Replacement of the module-local workqueue in 1394 OHCI PCI driver with a companion IRQ thread - Refactoring of bus management code - Additional minor code cleanup The existing tracepoints serve as an alternative to the removed debug parameter. The use of IRQ thread is experimental, as it handles 1394 OHCI SelfIDComplete event only. It may be replaced in the future releases with another approach; e.g. by providing workqueue from core functionality

Otherwise there's quite a bit of driver work, as well as some new drivers several existing drivers have had quite a bit of work done on them. Possibly the most interesting thing is the VirtIO driver, this is apparently useful for some automotive applications which want to keep as small and robust a host system as they can, moving less critical functionality into guests. - James Clark has done some substantial updates on the Freescale DSPI driver, porting in code from the BSP and building onm top of that to fix some bugs and increase performance. - Jonas Gorski has fixed the issues with handling multple chip selects, making things more robust and scalable. - Support for higher performance modes in the NXP FSPI driver from Haibo Chen. - Removal of the obsolete S3C2443 driver, the underlying SoC support has been removed from the kernel. - Support for Amlogic AL113L2, Atmel SAMA7D65 and SAM9x7 and for VirtIO controllers.
regulator: Updates for v6.18 This is a very quiet release for regulator, almost all the changes are new drivers but we do also have some improvements for the Rust bindings. - Additional APIs added to the Rust bindings. - Support for Maxim MAX77838, NXP PF0900 and PF5300, Richtek RT5133 and SpacemiT P1.
regmap: Updates for v6.18 This just contains a few small fixes, there's been no substantial development on regmap this release cycle.
Many thanks, -- Marco ------ >8 ------ Kernel Concurrency Sanitizer (KCSAN) updates for v6.18 - Replace deprecated strcpy() with strscpy() This change has had 6 weeks of linux-next exposure.
From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> Here's the PR containing the GPIO updates for this merge window. There are two new drivers and support for more models in existing ones. The generic GPIO API has been reworked and all users converted which allowed us to move the fields specific to the generic GPIO implementation out of the high-level struct gpio_chip into its own structure that wraps the gpio_chip. Other than that, there's nothing too exciting. Mostly minor tweaks and fixes all over the place, some refactoring and some small new features in helper modules. Details are in the signed tag. The merges you see here are either me pulling in MFD changes with GPIO drivers that depend on MFD changes or my own immutable branches provided for other trees. Thanks, Bartosz gpio updates for v6.18-rc1 GPIO core: - add support for sparse pin ranges to the glue between GPIO and pinctrl - use a common prefix across all GPIO descriptor flags for improved namespacing New drivers: - add new GPIO driver for the Nuvoton NCT6694 - add new GPIO driver for MAX7360 Driver improvements: - add support for Tegra 256 to the gpio-tegra186 driver - add support for Loongson-2K0300 to the gpio-loongson-64bit driver - refactor the gpio-aggregator module to expose its GPIO forwarder API to other in-kernel users (to enable merging of a new pinctrl driver that uses it) - convert all remaining drivers to using the modernized generic GPIO chip API and remove the old interface - stop displaying global GPIO numbers in debugfs output of controller drivers - extend the gpio-regmap helper with a new config option and improve its support for GPIO interrupts - remove redundant fast_io parameter from regmap configs in GPIO drivers that already use MMIO regmaps which imply it - add support for a new model in gpio-mmio: ixp4xx expansion bus - order includes alphabetically in a few drivers for better readability - use generic device properties where applicable - use devm_mutex_init() where applicable - extend build coverage of drivers by enabling more to be compiled with COMPILE_TEST enabled - allow building gpio-stmpe as a module - use dev_err_probe() where it makes sense in drivers Late driver fixes: - fix setting GPIO direction to output in gpio-mpfs Documentation: - document the usage of software nodes with GPIO chips Device-tree bindings: - Add DT bindings documents for new hardware: Tegra256, MAX7360 - Document a new model in Loongson bindings: LS2K0300 - Document a new model using the generic GPIO binding: IXP4xx - Convert the DT binding for fsl,mxs-pinctrl to YAML - fix the schema ID in the "trivial" GPIO schema - describe GPIO hogs in the generic GPIO binding

IRQ controller
Updates for interrupt chip drivers:
- Use the startup/shutdown callbacks for the PCI/MSI per device interrupt
domains.
This allows to initialize the RISCV PLIC interrupt hierarchy correctly
and provides a mechanism to decouple the masking and unmasking during
run-time from the expensive PCI mask and unmask when the underlying MSI
provider implementation allows the interrupt to be masked.
- Initialize the RISCV PLIC MSI interrupt hierarchy correctly so that the
affinity assignment works correctly by switching it over to the
startup/shutdown scheme
- Allow MSI providers to opt out from masking a PCI/MSI interrupt at the
PCI device during operation when the provider can mask the interrupt at
the underlying interrupt chip. This reduces the overhead in scenarios
where disable_irq()/enable_irq() is utilized frequently by a driver.
The PCI/MSI device level [un]masking is only required on startup and
shutdown in this case.
- Remove the conditional mask/unmask logic in the PCI/MSI layer as this
is now handled unconditionally.
- Replace the hardcoded interrupt routing in the Loongson EIOINTC
interrupt driver to respect the firmware settings and spread them out
to different CPU interrupt inputs so that the demultiplexing handler
only needs to read only a single 64-bit status register instead of
four, which significantly reduces the overhead in VMs as the status
register access causes a VM exit.
- Add support for the new AST2700 SCU interrupt controllers
- Use the legacy interrupt domain setup for the Loongson PCH-LPC
interrupt controller, which resembles the x86 legacy PIC setup and has
the same hardcoded legacy requirements.
- The usual set of cleanups, fixes and improvements all over the place
Thanks,

please pull the latest timers/core branch from:
-09-29
Updates for the time(rs) core subsystem:
- Address the inconsistent shutdown sequence of per CPU clockevents on
CPU hotplug, which onoly removed it from the core but failed to invoke
the actual device driver shutdown callback. This keeps the timer
active, which prevents power savings and causes pointless noise in
virtualization.
- Encapsulate the open coded access to the hrtimer clock base, which is a
private implementation detail, so that the implementation can be
changed without breaking a lot of usage sites.
- Enhance the debug output of the clocksource watchdog to provide better
information for analysis.
- The usual set of cleanups and enhancements all over the place
Thanks,

please pull the latest irq/core branch from:
-29
RT
A set of updates for the interrupt core subsystem:
- Introduce irq_chip_[startup|shutdown]_parent() to prepare for
addressing a few short comings in the PCI/MSI interrupt subsystem.
It allows to utilize the interrupt chip startup/shutdown callbacks for
initializing the interrupt chip hierarchy properly on certain RISCV
implementations and provides a mechanism to reduce the overhead of
masking and unmasking PCI/MSI interrupts during operation when the
underlying MSI provider can mask the interrupt.
The actual usage comes with the interrupt driver pull request.
- Add generic error handling for devm_request_*_irq()
This allows to remove the zoo of random error printk's all over the
usage sites.
- Add a mechanism to warn about long-running interrupt handlers
Long running interrupt handlers can introduce latencies and tracking
them down is a tedious task. The tracking has to be enabled with a
threshold on the kernel command line and utilizes a static branch to
remove the overhead when disabled.
- Update and extend the selftests which validate the CPU hotplug
interrupt migration logic
- Allow dropping the per CPU softirq lock on PREEMPT_RT kernels, which
causes contention and latencies all over the place.
The serialization requirements have been pushed down into the actual
affected usage sites already.
- The usual small cleanups and improvements

on, to link with glibc
Two fixes for RSEQ:
1) Protect the event mask modification against the membarrier() IPI as
otherwise the RmW operation is unprotected and events might be lost.
2) Fix the weak symbol reference in rseq selftests
The current weak RSEQ symbols definitions which were added to allow
static linkage are not working correctly as the effectively re-define
the glibc symbols leading to multiple versions of the symbols when
compiled with -fno-common. Mark them as 'extern' to convert them from
weak symbol definitions to weak symbol references. That works with
static and dynamic linkage independent of -fcommon and -fno-common.

This makes it pointlessly hard to add a new generic TIF bit or to change an existing one. Provide a generic variant and convert the architectures which utilize the generic entry code over to use it. The TIF space is divided into 16 generic bits and 16 architecture specific bits, which turned out to provide enough space on both sides. Thanks, tglx

(The pca9586 driver did that in a driver specific implementation before.) Otherwise it's the usual mix of fixes and device tree and driver changes to support new hardware variants. There is an immutable branch pending for this merge window that was created by Lee at t-pinctrl-pwm-v6.18 =2E I didn't add it here because it merges cleanly into my tree; you'll get it via Lee's PR and probably others, too. (For the next time such a situation arises: Would you prefer me including such a merge anyhow?) Otherwise this PR should be boring for you (https://www.youtube.com/watch?v=3DV_ioxeU7Kpw).

This pull request contains several fixes of syzbot reported issues, HFS/HFS+ fixes of xfstests failures, and rework of HFS/HFS+ debug output subsystem. Kang Chen has fixed a slab-out-of-bounds issue in hfsplus_uni2asc() when hfsplus_uni2asc() is called from hfsplus_listxattr(). Yang Chenzhi has fixed a crash in hfsplus_bmap_alloc() if record offset or length is larger than node_size. Yangtao Li made correction of returning error code from hfsplus_fill_super() if Catalog File contains corrupted record for the case of hidden directory's type. The KMSAN uninit-value issue has been fixed in hfs_find_set_zero_bits() by exchanging the kmalloc() on kzalloc() call. The KMSAN uninit-value issue in hfsplus_delete_cat() has been fixed by proper initialization of struct hfsplus_inode_info in the hfsplus_iget() logic. The KMSAN uninit-value issue in __hfsplus_ext_cache_extent() has been fixed by exchanging the kmalloc() on kzalloc() in hfs_find_init(). The slab-out-of-bounds issue could happen in hfsplus_strcasecmp() if the length field of struct hfsplus_unistr is bigger than HFSPLUS_MAX_STRLEN. The issue has been fixed by checking the length of comparing strings. And if the strings' length is bigger than HFSPLUS_MAX_STRLEN, then the length is corrected to this value. The generic/736 xfstest fails for HFS case because HFS volume becomes corrupted after the test run. The main reason of the issue is the absence of logic that corrects mdb->drNxtCNID/HFS_SB(sb)->next_id (next unused CNID) after deleting a record in Catalog File. It was introduced a hfs_correct_next_unused_CNID() method that implements the necessary logic. hfs updates for v6.18 - hfs/hfsplus: rework debug output subsystem - hfsplus: fix slab-out-of-bounds read in hfsplus_strcasecmp() - hfsplus: fix slab-out-of-bounds read in hfsplus_uni2asc() - hfs: clear offset and space out of valid records in b-tree node - hfs: add logic of correcting a next unused CNID - hfsplus: fix KMSAN uninit-value issue in hfsplus_delete_cat() - hfs: fix KMSAN uninit-value issue in hfs_find_set_zero_bits() - hfs: make proper initalization of struct hfs_find_data - hfsplus: fix KMSAN uninit-value issue in __hfsplus_ext_cache_extent() - hfs: validate record offset in hfsplus_bmap_alloc - hfsplus: return EIO when type of hidden directory mismatch in hfsplus_fill_super() - MAINTAINERS: update location of hfs&hfsplus trees

A small one this time. One of the trees I merge (pin-init) is going this
cycle through DRM for convenience.
No conflicts expected at this time. Nevertheless, I did a test merge and
tested it a bit and it seems fine.
When you merge other trees, you will have some. The resolutions in -next
should be fine, except for a `rustfmt` issue in one, so please remember
to double-check that on your merges (it may be solved by the time you
get to it).
All commits have been in linux-next for at least four rounds, most for
two weeks or more.
Cheers,
Miguel
Rust changes for v6.18
Toolchain and infrastructure:
- Derive 'Zeroable' for all structs and unions generated by 'bindgen'
where possible and corresponding cleanups. To do so, add the
'pin-init' crate as a dependency to 'bindings' and 'uapi'.
It also includes its first use in the 'cpufreq' module, with more to
come in the next cycle.
- Add warning to the 'rustdoc' target to detect broken 'srctree/' links
and fix existing cases.
- Remove support for unused (since v6.16) host '#[test]'s, simplifying
the 'rusttest' target. Tests should generally run within KUnit.
'kernel' crate:
- Add 'ptr' module with a new 'Alignment' type, which is always a power
of two and is used to validate that a given value is a valid
alignment and to perform masking and alignment operations:
// Checked at build time.
assert_eq!(Alignment::new::<16>().as_usize(), 16);
// Checked at runtime.
assert_eq!(Alignment::new_checked(15), None);
assert_eq!(Alignment::of::<u8>().log2(), 0);
assert_eq!(0x25u8.align_down(Alignment::new::<0x10>()), 0x20);
assert_eq!(0x5u8.align_up(Alignment::new::<0x10>()), Some(0x10));
assert_eq!(u8::MAX.align_up(Alignment::new::<0x10>()), None);
It also includes its first use in Nova.
- Add 'core::mem::{align,size}_of{,_val}' to the prelude, matching
Rust 1.80.0.
- Keep going with the steps on our migration to the standard library
'core::ffi::CStr' type (use 'kernel::{fmt, prelude::fmt!}' and use
upstream method names).
- 'error' module: improve 'Error::from_errno' and 'to_result'
documentation, including examples/tests.
- 'sync' module: extend 'aref' submodule documentation now that it
exists, and more updates to complete the ongoing move of 'ARef' and
'AlwaysRefCounted' to 'sync::aref'.
- 'list' module: add an example/test for 'ListLinksSelfPtr' usage.
- 'alloc' module:
- Implement 'Box::pin_slice()', which constructs a pinned slice of
elements.
- Provide information about the minimum alignment guarantees of
'Kmalloc', 'Vmalloc' and 'KVmalloc'.
- Take minimum alignment guarantees of allocators for
'ForeignOwnable' into account.
- Remove the 'allocator_test' (including 'Cmalloc').
- Add doctest for 'Vec::as_slice()'.
- Constify various methods.
- 'time' module:
- Add methods on 'HrTimer' that can only be called with exclusive
access to an unarmed timer, or from timer callback context.
- Add arithmetic operations to 'Instant' and 'Delta'.
- Add a few convenience and access methods to 'HrTimer' and
'Instant'.
'macros' crate:
- Reduce collections in 'quote!' macro.
And a few other cleanups and improvements.
Note, there is a trivial conflict between tip and bpf-next trees:
in kernel/events/uprobes.c between commit:
4363264111e12 ("uprobe: Do not emulate/sstep original instruction when ip is changed")
from the bpf-next tree and commit:
ba2bfc97b4629 ("uprobes/x86: Add support to optimize uprobes")
from the tip tree:
https://lore.kernel.org/all/aNVMR5rjA2geHNLn@sirena.org.uk/
since Jiri's two separate uprobe/bpf related patch series landed
in different trees. One was mostly uprobe. Another was mostly bpf.
Other than that the main changes are:
- Support pulling non-linear xdp data with bpf_xdp_pull_data() kfunc
(Amery Hung).
Applied as a stable branch in bpf-next and net-next trees.
- Support reading skb metadata via bpf_dynptr (Jakub Sitnicki).
Also a stable branch in bpf-next and net-next trees.
- Enforce expected_attach_type for tailcall compatibility
(Daniel Borkmann)
- Replace path-sensitive with path-insensitive live stack analysis
in the verifier (Eduard Zingerman).
This is a significant change in the verification logic. More details,
motivation, long term plans are in the cover letter/merge commit.
- Support signed BPF programs (KP Singh).
This is another major feature that took years to materialize.
Algorithm details are in the cover letter/marge commit.
- Add support for may_goto instruction to s390 JIT (Ilya Leoshkevich)
- Add support for may_goto instruction to arm64 JIT (Puranjay Mohan)
- Fix USDT SIB argument handling in libbpf (Jiawei Zhao)
- Allow uprobe-bpf program to change context registers (Jiri Olsa)
- Support signed loads from BPF arena (Kumar Kartikeya Dwivedi
and Puranjay Mohan)
- Allow access to union arguments in tracing programs (Leon Hwang)
- Optimize rcu_read_lock() + migrate_disable() combination
where it's used in BPF subsystem (Menglong Dong)
- Introduce bpf_task_work_schedule*() kfuncs to schedule
deferred execution of BPF callback in the context of
a specific task using the kernel’s task_work infrastructure
(Mykyta Yatsenko)
- Enforce RCU protection for KF_RCU_PROTECTED kfuncs
(Kumar Kartikeya Dwivedi)
- Add stress test for rqspinlock in NMI
(Kumar Kartikeya Dwivedi)
- Improve the precision of tnum multiplier verifier operation
(Nandakumar Edamana)
- Use tnums to improve is_branch_taken() logic (Paul Chaignon)
- Add support for atomic operations in arena in riscv JIT (Pu Lehui)
- Report arena faults to BPF error stream (Puranjay Mohan)
- Search for tracefs at /sys/kernel/tracing first in bpftool
(Quentin Monnet)
- Add bpf_strcasecmp() kfunc (Rong Tao)
- Support lookup_and_delete_elem command in BPF_MAP_STACK_TRACE
(Tao Chen)

Hi Rafael, after an error reported by kbuild test, it appears a file missed when importing the RZ/G3E new driver which stayed locally after a conflict resolution. This change is on top of the previous tag. Alternatively, if you wish to drop the previous PR, I can emit a new PR with this offending change fixed, IOW this fix folded with initial patch (which sounds cleaner to me BTW). - Add missing file when importing conflicting change for the Renesas RZ/G3E thermal driver (Daniel Lezcano)
- Add a RISC-V optimized implementation of Poly1305. This code was
written by Andy Polyakov and contributed by Zhihang Shao.
- Migrate the MD5 code into lib/crypto/, and add KUnit tests for MD5.
Yes, it's still the 90s, and several kernel subsystems are still
using MD5 for legacy use cases. As long as that remains the case,
it's helpful to clean it up in the same way as I've been doing for
other algorithms. Later, I plan to convert most users of MD5 to use
the new MD5 library API instead of the generic crypto API.
- Simplify the organization of the ChaCha, Poly1305, BLAKE2s, and
Curve25519 code. Consolidate these into one module per algorithm,
and centralize the configuration and build process. This is the same
reorganization that has already been successful for SHA-1 and SHA-2.
- Remove the unused crypto_kpp API for Curve25519.
- Migrate the BLAKE2s and Curve25519 self-tests to KUnit.
- Always enable the architecture-optimized BLAKE2s code.
Due to interdependencies between test and non-test code, both are
included in this pull request. The broken-down diffstat is as follows:
Tests: 735 insertions(+), 1917 deletions(-)
RISC-V Poly1305: 877 insertions(+), 1 deletion(-)
Other: 1777 insertions(+), 3117 deletions(-)
Besides the new RISC-V code which is an addition, there are quite a
few simplifications due to the improved code organization for multiple
algorithms, the removal of the unused crypto_kpp API for Curve25519
and redundant tests, and the redesign of the BLAKE2s test.
Note: this depends on the pull request "[GIT PULL 03/12 for v6.18] inode" from Christian Brauner. Add support for 2-way interleaved SHA-256 hashing to lib/crypto/, and make fsverity use it for faster file data verification. This improves fsverity performance on many x86_64 and arm64 processors. Later, I plan to make dm-verity use this too.
Make fs/crypto/ use the HMAC-SHA512 library functions instead of crypto_shash. This is simpler, faster, and more reliable.
Update crc_kunit to test the CRC functions in softirq and hardirq contexts, similar to what the lib/crypto/ KUnit tests do. Move the helper function needed to do this into a common header. This is useful mainly to test fallback code paths for when FPU/SIMD/vector registers are unusable.
Hi Wolfram, this merge window pull request is rather small, and the blame is all on me. It has been a very messy period, leaving me with little time to look after the patches for 6.18. That said, I now have quite a bit of work ahead, but I am confident that with the next pull request I will manage to slim the queue down. For now, I hope you will not mind a second part of this pull request, where I plan to include the most obvious patches from those still in the queue. Thank you and wishing you a great weekend, Andi i2c-host for v6.18 dt-bindings: - add support for MediaTek MT6878 I2C - Drp[ support fpr S3C2410
cgroup: Changes for v6.18 - Extensive cpuset code cleanup and refactoring work with no functional changes: CPU mask computation logic refactoring, introducing new helpers, removing redundant code paths, and improving error handling for better maintainability. - A few bug fixes to cpuset including fixes for partition creation failures when isolcpus is in use, missing error returns, and null pointer access prevention in free_tmpmasks(). - Core cgroup changes include replacing the global percpu_rwsem with per-threadgroup rwsem when writing to cgroup.procs for better scalability, workqueue conversions to use WQ_PERCPU and system_percpu_wq to prepare for workqueue default switching from percpu to unbound, and removal of unused code including the post_attach callback. - New cgroup.stat.local time accounting feature that tracks frozen time duration. - Misc changes including selftests updates (new freezer time tests and backward compatibility fixes), documentation sync, string function safety improvements, and 64-bit division fixes.
workqueue: Changes for v6.18 - WQ_PERCPU was added to remaining alloc_workqueue() users and system_wq usage was replaced with system_percpu_wq and system_unbound_wq with system_dfl_wq. These are equivalent conversions with no functional changes, preparing for switching default to unbound workqueues from percpu. - A handshake mechanism was added for canceling BH workers to avoid live lock scenarios under PREEMPT_RT. - Unnecessary rcu_read_lock/unlock() calls were dropped in wq_watchdog_timer_fn() and workqueue_congested(). - Documentation was fixed to resolve texinfodocs warnings.
sched_ext: Changes for v6.18 - Code organization cleanup. Separate internal types and accessors to ext_internal.h to reduce the size of ext.c and improve maintainability. - Prepare for cgroup sub-scheduler support by adding @sch parameter to various functions and helpers, reorganizing scheduler instance handling, and dropping obsolete helpers like scx_kf_exit() and kf_cpu_valid(). - Add new scx_bpf_cpu_curr() and scx_bpf_locked_rq() BPF helpers to provide safer access patterns with proper RCU protection. scx_bpf_cpu_rq() is deprecated with warnings due to potential race conditions. - Improve debugging with migration-disabled counter in error state dumps, SCX_EFLAG_INITIALIZED flag, bitfields for warning flags, and other enhancements to help diagnose issues. - Use cgroup_lock/unlock() for cgroup synchronization instead of scx_cgroup_rwsem based synchronization. This is simpler and allows enable/disable paths to synchronize against cgroup changes independent of the CPU controller. - rhashtable_lookup() replacement to avoid redundant RCU locking was reverted due to RCU usage warnings. Will be redone once rhashtable is updated to use rcu_dereference_all(). - Other misc updates and fixes including bypass handling improvements, scx_task_iter_relock() improvements, tools/sched_ext updates, and compatibility helpers.
[sending this early as I'm fishing on Monday]
across the board, including some nice mm improvements for CPUs with
the "noabort" BBML2 feature and a clever patch to allow ptdump to play
nicely with block mappings in the vmalloc area.
We've only had a couple of trivial conflicts show up in -next:
* The fs-next tree has taken clone3() support for shadow stacks and
this gives rise to a simple context conflict in our asm/gcs.h.
There's been some late ABI feedback from the glibc community,
however, so maybe Christian will end up dropping the patches [1].
* The kbuild tree has removed the tautological dependency that
CONFIG_CPU_BIG_ENDIAN has on the assembler version. However, we've
extended that to make it depend on BROKEN in anticipation of
dropping support altogether.
I've already got a handful of minor fixes to go on top but I'll send
those separately once they've had a chance to sit in -next.
Summary in the tag.
Cheers,
Will

arm64 updates for 6.18
Confidential computing:
- Add support for accepting secrets from firmware (e.g. ACPI CCEL)
and mapping them with appropriate attributes.
CPU features:
- Advertise atomic floating-point instructions to userspace.
- Extend Spectre workarounds to cover additional Arm CPU variants.
- Extend list of CPUs that support break-before-make level 2 and
guarantee not to generate TLB conflict aborts for changes of mapping
granularity (BBML2_NOABORT).
- Add GCS support to our uprobes implementation.
Documentation:
- Remove bogus SME documentation concerning register state when
entering/exiting streaming mode.
Entry code:

- Rework rodata= for closer parity with the behaviour on x86.
- For CPUs implementing BBML2_NOABORT, utilise block mappings in the
linear map even when rodata= applies to virtual aliases.
- Don't re-allocate the virtual region between '_text' and '_stext',
as doing so confused tools parsing /proc/vmcore.
Miscellaneous:
- Clean-up Kconfig menuconfig text for architecture features.
- Avoid redundant bitmap_empty() during determination of supported
SME vector lengths.
- Re-enable warnings when building the 32-bit vDSO object.
- Avoid breaking our eggs at the wrong end.

- Sync TCR_EL1 definition with the latest Arm ARM (L.b).
- Be stricter about the input fed into our AWK sysreg generator script.
- Typo fixes and removal of redundant definitions.
ACPI, EFI and PSCI:
- Decouple Arm's "Software Delegated Exception Interface" (SDEI)
support from the ACPI GHES code so that it can be used by platforms
booted with device-tree.
- Remove unnecessary per-CPU tracking of the FPSIMD state across EFI
runtime calls.
- Fix a node refcount imbalance in the PSCI device-tree code.
CPU Features:
- Ensure register sanitisation is applied to fields in ID_AA64MMFR4.
- Expose AIDR_EL1 to userspace via sysfs, primarily so that KVM guests
can reliably query the underlying CPU types from the VMM.
- Re-enabling of SME support (CONFIG_ARM64_SME) as a result of fixes
to our context-switching, signal handling and ptrace code.
Locking updates for v6.16 mostly include Rust runtime enhancements: - Add initial support for generic LKMM atomic variables in Rust. (Boqun Feng) - Add the wrapper for `refcount_t` in Rust. (Gary Guo) - Make `data` in `Lock` structurally pinned. (Daniel Almeida) - Add a new reviewer, Gary Guo. Thanks, Ingo

This is the batch of pull requests for the v6.18 merge window! This was a pretty usual cycle. Not light, not particularly heavy. There are a few minor filesystem specific changes such as afs and pidfs but nothing that's really worth mentioning. Same goes for iomap and rust. There are some changes around clone3() and copy_process() that lead to some cleanups. There's some workqueue chagnes that affect all of fs but it's not all that exciting and we don't have to care once all the cleanup is done and the semantics for per-cpu and unbounded workqueues are simplified and clarified. There's a pretty interesting writeback series by Jan Kara that fixes a nasty issue causing lockups reported by users when a systemd unit reading lots of files from a filesystem mounted with the lazytime mount option exits. With the lazytime mount option enabled we can be switching many dirty inodes on cgroup exit to the parent cgroup. The numbers observed in practice when a systemd slice of a large cron job exits can easily reach hundreds of thousands or millions. The overall time complexity of switching all the inodes to the correct wb is quadratic leading to workers being pegged for hours consuming 100% of the CPU and switching inodes to the parent wb. That issue should be gone. We also have a series that shrinks struct inode by 16 bytes. This is really something I care about because struct inode in contrast to struct file and struct dentry both of which are meticulously clean by now (I mean, it could alwasy be better, but you know...) struct inode is still a giant dumping ground where everyone is made to pay for features that only 3 filesystems actually end up using. First step, I've moved fscrpt and fsverity pointers out of struct inode and into the individual filesystems that care about this. Hopefully more to come in that area. There's also some preliminary cleanup related to the inode lifetime rework that is currently under way leading to less open-coded accesses to internal inode members and some simplifications for iput_final(). Last but not least there's a bunch of namespace related rework this cycle. This specifically also addresses a complaint you had a few weeks back about ns_alloc_inum(). That's now completely gone and so is the special-casing of the init network namespace initialization. Initialization, reference counting, and cleanup are now unified and statically derived from the namespace type allowing the compiler to catch obvious bugs. The namespace iterator infrastructure I did for the mount namespace some time back is now extended and generalized to cover all other namespace types. As a first step this allows the implemenation of namespace file handles. As with pidfs file handles, namespace file handles are exhaustive, meaning it is not required to actually hold a reference to nsfs to be able to decode aka open_by_handle_at() a namespace file handle. It has the same advantage as pidfs file handles have. It's possible to reliably and for the lifetime of the system refer to a namespace without pinning any resources and to compare them trivially. The namespace file handle layout is exposed as uapi and has a stable and extensible format. The stable format means that userspace may construct its own namespace file handles without going through name_to_handle_at(). Thanks! Christian
( Merge note: we've stopped using Link tags for the purpose of tip-bot
lkml email notifications during the v6.18 development window, and
thus commits applied after September 15-ish only have Links if they
are particularly informative. Commits before that still have the
old-style Link tags. )
Scheduler updates for v6.18:
Core scheduler changes:
- Make migrate_{en,dis}able() inline, to improve performance
(Menglong Dong)
- Move STDL_INIT() functions out-of-line (Peter Zijlstra)
- Unify the SCHED_{SMT,CLUSTER,MC} Kconfig (Peter Zijlstra)
Fair scheduling:
- Defer throttling when tasks exit to user-space, to reduce the
chance & impact of throttle-preemption with held locks and
other resources. (Aaron Lu, Valentin Schneider)
- Get rid of sched_domains_curr_level hack for tl->cpumask(),
as the warning was getting triggered on certain topologies.
(Peter Zijlstra)
Misc cleanups & fixes:
- Header cleanups (Menglong Dong)
- Fix race in push_dl_task() (Harshit Agarwal)
Thanks,
Ingo
Please git pull the following tag: xen: branch for v6.18-rc1 It contains the following patches: - a 3 patch series fixing the migration of a Xen virq to another cpu plus some related cleanup work - a 3 patch series cleaning up Xen-PV mode specific code, resulting in removing some of that code in the resulting binary in case CONFIG_XEN_PV is not set - 2 fixes and 1 cleanup patch for suspend handling under Xen Thanks. Juergen arch/x86/configs/xen.config | 1 -
please pull the x86/apic lineup for v6.18-rc1. The AMD SEV (encrypted guests and hypervisor support) side of things received a lot of development this time around and you should be getting a lot of code from several trees. Even this branch contains two big features because it was deemed a better idea to merge them into one. So there might be other merge conflicts, like with the crypto tree, for example: https://lore.kernel.org/r/aM1bJqhtojdLhp3c@sirena.org.uk The resolution should be easy but lemme give you a heads-up anyway. Thx. --- - Add functionality to provide runtime firmware updates for the non-x86 parts of an AMD platform like the security processor (ASP) firmware, modules etc, for example. The intent being that these updates are interim, live fixups before a proper BIOS update can be attempted - Add guest support for AMD's Secure AVIC feature which gives encrypted guests the needed protection against a malicious hypervisor generating unexpected interrupts and injecting them into such guest, thus interfering with its operation in an unexpected and negative manner. The advantage of this scheme is that the guest determines which interrupts and when to accept them vs leaving that to the benevolence (or not) of the hypervisor - Strictly separate the startup code from the rest of the kernel where former is executed from the initial 1:1 mapping of memory. The problem was that the toolchain-generated version of the code was being executed from a different mapping of memory than what was "assumed" during code generation, needing an ever-growing pile of fixups for absolute memory references which are invalid in the early, 1:1 memory mapping during boot. The major advantage of this is that there's no need to check the 1:1 mapping portion of the code for absolute relocations anymore and get rid of the RIP_REL_REF() macro sprinkling all over the place. For more info, see Ard's very detailed writeup on this: https://lore.kernel.org/r/CAMj1kXEzKEuePEiHB%2BHxvfQbFz0sTiHdn4B%2B%2BzVBJ2mhkPkQ4Q@mail.gmail.com - The usual cleanups and fixes
please pull the x86/cache lineup for v6.18-rc1. Thx. --- - Add support on AMD for assigning QOS bandwidth counters to resources (RMIDs) with the ability for those resources to be tracked by the counters as long as they're assigned to them. Previously, due to hw limitations, bandwidth counts from untracked resources would get lost when those resources are not tracked. Refactor the code and user interfaces to be able to also support other, similar features on ARM, for example
please pull the x86/cpu lineup for v6.18-rc1. Thx. --- - Make UMIP instruction detection more robust - Correct and cleanup AMD CPU topology detection; document the relevant CPUID leaves topology parsing precedence on AMD - Add support for running the kernel as guest on FreeBSD's Bhyve hypervisor - Cleanups and improvements
please pull the x86/bugs lineup for v6.18-rc1. Thx. --- - Add VMSCAPE to the attack vector controls infrastructure - A bunch of the usual cleanups and fixlets, some of them resulting from fuzzing the different mitigation options
please pull the RAS lineup for v6.18-rc1. Thx. --- - Unify and refactor the MCA arch side and better separate code - Cleanup and simplify the AMD RAS side, unify code, drop unused stuff
please pull the x86/microcode lineup for v6.18-rc1. Thx. --- - Add infrastructure to be able to debug the microcode loader in a guest - Refresh Intel old microcode revisions
please pull a x86/asm fix for v6.18-rc1. Thx. --- - Fix RDPID's output operand size in inline asm and use the insn mnemonic because the minimum binutils version supports it
please pull a single x86/misc update for v6.18-rc1. Thx. --- - Add instruction decoding support for the XOP-prefixed instruction set present on the AMD Bulldozer uarch
please pull the x86/build lineup for v6.18-rc1. Thx. --- - Remove and simplify a bunch of cc-option and compiler version checks in the build machinery now that the minimal version of both compilers supports them
please pull the EDAC lineup for v6.18. Thx. --- - Add support for new AMD family 0x1a models to amd64_edac - Add an EDAC driver for the AMD VersalNET memory controller which reports hw errors from different IP blocks in the fabric using an IPC-type transport - Drop the silly static number of memory controllers in the Intel EDAC drivers (skx, i10nm) in favor of a flexible array so that former doesn't need to be increased with every new generation which adds more memory controllers; along with a proper refactoring - Add support for two Alder Lake-S SOCs to ie31200_edac - Add an EDAC driver for ADM Cortex A72 cores, and specifically for reporting L1 and L2 cache errors - Last but not least, the usual fixes, cleanups and improvements all over the subsystem

Hi SoC maintainers, Here's the first batch of PXA1908 DT changes for 6.18. Regards, Duje
Hi Arnd, The bus/fsl-mc changes outside soc/fsl tree are acked by maintainer of QORIQ DPAA2 FSL-MC BUS DRIVER. Thanks Christophe FSL SOC Changes for 6.18: - Use for_each_online_cpu() instead of for_each_cpu() in qbman - Update FSL QUICC ENGINE GPIO driver to a standard platform driver and stop using legacy-of-mm-gpiochip.h header - Misc fixes on bus/fsl-mc
Hi,
please pull the following updates for btrfs. There are no new features,
the changes are in the core code, notably tree-log error handling and
reporting improvements, and initial support for block size > page size.
(There's one build warning due to printk format mismatch reported on
i386, we'll fix it before rc1. I did not consider it serious enough to
rework and delay the whole pull request.)
Performance improvements:
- search data checksums in the commit root (previous transaction) to
avoid locking contention, this improves parallelism of read heavy/low
write workloads, and also reduces transaction commit time;
on real and reproducer workload the sync time went from minutes to
tens of seconds (workload and numbers are in the changelog)
Core:
- tree-log updates
- error handling improvements, transaction aborts
- add new error state 'O' (printed in status messages) when log replay
fails and is aborted
- reduced number of btrfs_path allocations when traversing the tree
- 'block size > page size' support
- basic implementation with limitations, under experimental build
- limitations: no direct io, raid56, encoded read (standalone and in
send ioctl), encoded write
- preparatory work for compression, removing implicit assumptions of
page and block sizes
- compression workspaces are now per-filesystem, we cannot assume
common block size for work memory among different filesystems
- tree-checker now verifies INODE_EXTREF item (which is implementing
hardlinks)
- tree leaf pretty printer updates, there were missing data from items,
keys/items
- move config option CONFIG_BTRFS_REF_VERIFY to CONFIG_BTRFS_DEBUG,
it's a debugging feature and not needed to be enabled separately
- more struct btrfs_path auto free updates
- use ref_tracker API for tracking delayed inodes, enabled by mount
option 'ref_verify', allowing to better pinpoint leaking references
- in zoned mode, avoid selecting data relocation zoned for ordinary data
block groups
- updated and enhanced error messages
- lots of cleanups and refactoring
NIOS2: update for v6.18 - Replace __ASSEMBLY__ with __ASSEMBLER__ in headers - Set memblock.current_limit when setting pfn limits
LoongArch KVM changes for v6.18 1. Add PTW feature detection on new hardware. 2. Add sign extension with kernel MMIO/IOCSR emulation. 3. Improve in-kernel IPI emulation. 4. Improve in-kernel PCH-PIC emulation. 5. Move kvm_iocsr tracepoint out of generic code.
please consider pulling the following gfs2 changes for 6.18. gfs2 changes - Partially revert "gfs2: do_xmote fixes" to ignore dlm_lock() errors during withdraw; passing on those errors doesn't help. - Change the LM_FLAG_TRY and LM_FLAG_TRY_1CB logic in add_to_queue() to check if the holder would actually block. - Move some more dlm specific code from glock.c to lock_dlm.c. - Remove the unused dlm alternate locking mode code. - Add proper locking to make sure that dlm lockspaces are never used after being released. - Various other cleanups.
From: Nicolas Ferre <nicolas.ferre@microchip.com> Dear arm-soc maintainers, Here are the first dt changes for 6.18 which contain some little node additions. The QSPI node has its bindings accepted and going with the SPI tree: https://lore.kernel.org/lkml/20250908-microchip-qspi-v2-0-8f3d69fdd5c9@microchip.com/ Thanks, best regards, Nicolas Microchip AT91 device tree updates for v6.18 This update includes: - sama7d65 and curiosity board: addition of gpio, leds and usart3 - sam9x75: qspi node - one cleanup
This is the pull request with interconnect changes for the v6.18-rc1 merge window. As always, the summary is in the signed tag. All patches have been in linux-next for a full week. There are currently Thanks, Georgi interconnect changes for 6.18 This pull request contains the interconnect changes for the 6.18-rc1 merge window. It contains new driver and a minor core cleanup. Core change: - Use device_match_of_node() instead of open coding it Driver changes: - Add new driver for the Qualcomm Glymur SoC - Enable OSM L3 support for the QCS615 SoC Signed-off-by: Georgi Djakov <djakov@kernel.org>
Apple SoC driver updates for 6.18 Krzysztof Kozlowski asked us to move away from generic compatibles: - Adjust all dt-bindings to use apple,t8103-XXXX instead of apple,XXXX as fallback and add a comment that the old generic list should no longer be extended. - Add new fallback compatibles to pinctrl, pmdomain, spi, and mca drivers. These changes have been Acked by their subsystem maintainers to be merged through our tree together with the dt-bindings. Support for pre-M1 Apple Silicon: - SART and mailbox gain support for Apple's A11, which are both required for NVMe. - NVMe also gains support for Apple's A11 and the nvme maintainers prefer that we merge this through the soc tree together with the mailbox and SART changes. - SPMI compatibles for A11 and T2 have been added, also going through the soc tree due to conflicts with the generic compatible removal and because no driver change is required. Signed-off-by: Sven Peter <sven@kernel.org>
Hi Peter & Ingo, than usual because I was at Kangrejos conference this week, however the changes are relatively small and simple, so I think it's Ok for v6.18. I also try using "git notes" for submission links as Thomas suggests, let see how it goes ;-) Locking changes for v6.18: - Fix a data-race in do_raw_write_lock reported by KCSAN Rust locking changes for v6.18 - Make `data` in `Lock` structurally pinned. Previously the `data` field of a `Lock<T>` is not structurally pinned, and it's impossible to initialize the `data` field with a pin-initializer, hence e.g. a `Lock<T>` where T is a pin-initialized type is not supported. This encourages workarounds like `Lock<Pin<KBox<T>>`, which is more complicated and less efficient. Therefore make the `data` field in `Lock` structurally pinned to support pin-initialized types in a `Lock<T>`. Since the `data` field is structurally pinned, make `Guard<T, ...>` only `DerefMut` is T is Unpin, otherwise `Guard::as_mut()` is added to provide a `Pin<&mut T>`. This is different than normal Rust standand library locks. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEj5IosQTPz8XU1wRHSXnow7UH+rgFAmjNGoEACgkQSXnow7UH +riU8ggAnRUTBam8NTmHJpZfVbbNSfx1ndaARxd9Wb/MLEh8OHYKbVRPJwvWGge+ dafO0VYULku7ho1SeIlLXp4Bbjy3YC6o/J6xOpr9xMmysUky7RHi+Ys0y9gKaSmW daPurQEOS8TBUWu5yVxNAfWoRgPEiPULovbzgANKKAV7QsljyoEg7mQCPxLftPze Hr22HxU+lr6SDH5Efc8ihGqXJAvwunk+0mkJymZbjWo3ZF3cuhXlTMcIlu1SK14a R1VQu5UoX8S5y0T0gkJ84UJ11e0wrSZyT0EqmHWSpVBnyGgWk8H1u284hDiGG2iG FvwoSQ9iVuxLhxjhPUSOjq30DzmFfg== =MZj4 -----END PGP SIGNATURE-----

Hi, if that is needed. Keystone2 device tree updates for v6.18 Cosmetic cleanups: * dt-bindings: Convert ti,keystone to DT schema
Hi Dave and Sima,
Besides the DRM changes, this PR also contains some new DMA & scatterlist
infrastructure (incl. some alloc dependencies), with Nova as a first user.
It also includes a few AsBytes and FromBytes additions needed by Nova.
I merged this cycle's pin-init PR from Benno, since Nova is the first user
taking advantage of the new features included.
There are a couple of conflicts with other trees (Rust, MM, Driver Core, Li=
nus),
but they are mostly around includes and all trivial [1..8] -- no semantic
conflicts.
All changes have been in -next for a couple of rounds; the latest nova-core
series from Alex for one cycle.

From: Nicolas Ferre <nicolas.ferre@microchip.com> Dear arm-soc maintainers, Here are the at91 soc changes for 6.18. They are move specific to at91 product line and are all related to PM code. Nicolas Microchip arm-soc updates for v6.18 This update includes: - low priority fixes to the PM code, in relation to recent addition of sam9x75 or sama7d65 SoCs - removal of the 2.5V regulator for low power modes since this is no longer supported
From: Nicolas Ferre <nicolas.ferre@microchip.com> Dear clock maintainers, Here are the first clk changes for 6.18. I don't think they have conflict with changes for the deprecated round_rate() to determine_rate() topic. They are in linux-next for a couple of days. Nicolas Microchip clock updates for v6.18 This update includes: - add one clock for sam9x75 - new meaning for MCR register field in clk-master - use force-write to PLL update register to ensure reliable programming sequence - update Analog Control Register (ACR) management to accommodate differences across SoCs
i.MX clock changes for 6.18 - Rework the i.MX95 BLK CTL driver to add the platform data to the state container. - Retain the state of the i.MS95 BLK CTL registers through both runtime and system suspend.
the TEE subsystem as described below. The QTEE patches depend on two patches from branch '20250911-qcom-tee-using-tee-ss-without-mem-obj-v12-2-17f07a942b8d@oss.qualcomm.com' Björn asked me [2] to pull them from his tree. This pull request is based on my previous pull request with tee-prot-dma-buf-for-v6.18 to avoid a few conflicts when merging. [1] https://lore.kernel.org/op-tee/20250911-qcom-tee-using-tee-ss-without-mem-obj-v12-0-17f07a942b8d@oss.qualcomm.com/ [2] https://lore.kernel.org/op-tee/mir6lhkj456ra3i6w7def4rrtzw663f66l66cz4s3gxxvueeqk@ils2hjklbp4y/ Thanks, Jens Add Qualcomm TEE driver (QTEE) This introduces a Trusted Execution Environment (TEE) driver for Qualcomm TEE (QTEE). QTEE enables Trusted Applications (TAs) and services to run securely. It uses an object-based interface, where each service is an object with sets of operations. Kernel and userspace services are also available to QTEE through a similar approach. QTEE makes callback requests that are converted into object invocations. These objects can represent services within the kernel or userspace process. We extend the TEE subsystem to understand object parameters and an ioctl call so client can invoke objects in QTEE: - TEE_IOCTL_PARAM_ATTR_TYPE_OBJREF_* - TEE_IOC_OBJECT_INVOKE The existing ioctl calls TEE_IOC_SUPPL_RECV and TEE_IOC_SUPPL_SEND are used for invoking services in the userspace process by QTEE. The TEE backend driver uses the QTEE Transport Message to communicate with QTEE. Interactions through the object INVOKE interface are translated into QTEE messages. Likewise, object invocations from QTEE for userspace objects are converted into SEND/RECV ioctl calls to supplicants.
From: Nicolas Ferre <nicolas.ferre@microchip.com> Dear arm-soc maintainers, Here are the SoC changes for 6.18 which set the Kconfig infrastrucutre for addition of the Microchip LAN969x SoC. Thanks, best regards, Nicolas Microchip ARM64 SoC updates for v6.18: This update includes: - basic infrastructure support for Microchip LAN969x SoC - SoC ARCH symbols (existing SparX-5, new LAN969x) under the ARCH_MICROCHIP hidden symbol (already in use by AT91 in 6.17) - addition of that new symbol for drivers that are shared by Microchip SoC-s now and in the future
This is a second 6.18 PR for the ASPEED devicetrees, following the first at [1]. Cheers, Andrew [1]: https://lore.kernel.org/soc/cb634cffaf0db9d25fb3062f0eee41e03955321f.c= amel@codeconstruct.com.au/ --- Further ASPEED devicetree updates for v6.18 New platforms: - Meta Clemente Clemente is a compute-tray platform using an AST2600 SoC Updated platforms: - Harma (Meta): Hot-swap controller, power monitoring, GPIO names There are also some devicetree cleanups from Rob and Krzysztof that touch a variety of platforms and the DTSIs. These lead to fewer warnings emitted fo= r the ASPEED devicetrees.
Hi Danilo,
As discussed with Miguel, I'm sending my PR to you this time.
The code changes themselves aren't that big, but functionality-wise
there are three important ones: pin-projections, code blocks and access
to previously initialized fields. More syntax changes will be on the way
for v6.19 and I hope I'll be a bit earlier in that cycle :)
The commits have been in linux-next for one day.
I have a conflict with your devres fix that's in -rc3, the resolution in
linux-next looks good.

Cheers,
Benno

Samsung Exynos SROM: Fix IO map resource leak if of_platform_populate() in probe() failed. 3. Broadcom brcmstb: Document existing, older devices in Devicetree bindings. 4. Tegra 210 EMC: Document OPP table for interconnects (driver usage will come later) and define memory client IDs as bindings, because these are shared between DTS and driver.
Hi, Samsung SoC driver sfor v6.18. This should be my last Samsung pull for this merge window. Best regards, Krzysztof Samsung SoC drivers for v6.18 1. Google GS101: Enable CPU Idle, which needs programming C2 idle hints via ACPM firmware (Alive Clock and Power Manager). The patch introducing this depends on 'local-timer-stop' Devicetree property, which was merged in v6.17. Fix handling error codes in ACPM firmware driver when talking to PMIC. 2. Exynos2200: Add dedicated compatible for serial engines (USI).
subsystem. There's a brief desciption in the tag below. All patches but "dma-buf: dma-heap: export declared functions" are withing the TEE subsystem. The dma-heap maintainer, Sumit Semwal, has acked the dma-heap patch to be merged via my tree. I believe I've addressed all comments from the reviews including providing a demo as described in [1]. [1] https://lore.kernel.org/op-tee/20250911135007.1275833-1-jens.wiklander@linaro.org/ Thanks, Jens TEE protected DMA-bufs for v6.18 - Allocates protected DMA-bufs from a DMA-heap instantiated from the TEE subsystem. - The DMA-heap uses a protected memory pool provided by the backend TEE driver, allowing it to choose how to allocate the protected physical memory. - Three use-cases (Secure Video Playback, Trusted UI, and Secure Video Recording) have been identified so far to serve as examples of what can be expected. - The use-cases have predefined DMA-heap names, "protected,secure-video", "protected,trusted-ui", and "protected,secure-video-record". The backend driver registers protected memory pools for the use-cases it supports.

Samsung DTS ARM changes for v6.18 1. Drop S3C2416 SoC from bindings, because it was removed from kernel in 2023. 2. Add Ethernet attached via SROM controller (memory bus) on SMDK5250. This wasn't tested, but code should work just like it is working on Exynos5410-based boards.
Samsung SoC clock drivers changes for 6.18
1. Tesla FSD: Expose CSI clocks to consumers (DTS).
2. Exynos990:
- Few fixes for fixed factor clocks, register widths and proper PLL
parents.
- Add four more clocks for the DPU and HSI0 clock for USB.
- Add PERIC0 and PERIC1 clock controllers (CMU), responsible for
providing clocks to serial engines.
3. Add seven clock controllers for the new Axis ARTPEC-8 SoC. The SoC
shares all main blocks, including the clock controllers, with Samsung
SoC, so same drivers and bindings are used.
4. Cleanups: switch to determine_rate().
Samsung pinctrl drivers changes for v6.18 1. Add pin controller drivers for new Axis ARTPEC-8 SoC. The SoC shares all main blocks, including the pin controller, with Samsung SoC, so same drivers and bindings are used. 2. Drop remaining support for Samsung S3C2410 SoC pin controllers. The actual SoC support was removed in January 2023, so this is just remaining cleanup.
Hi Greg, Just two minor improvements. Best regards, Krzysztof 1-Wire bus drivers for v6.18 1. Correct missing interrupts in IMX 1-Wire Devicetree bindings. 2. Drop old, dead code from Matrox driver.
Samsung SoC defconfig changes for v6.18 1. Cleanup MTD_NAND_S3C2410, being removed from the kernel via separate tree. 2. Enable Axis ARTPEC SoC in arm64 defconfig - new Samsung subarch.
Hi Stephen, Yixun Lan RISC-V SpacemiT clock changes for 6.18 - Convert to use determine_rate() - Fix clocks of SSPA
T-HEAD Devicetrees for v6.18 Add a device tree node for the IMG BXM-4-64 GPU present in the T-HEAD TH1520 SoC used by the Lichee Pi 4A board. This node enables support for the GPU using the drm/imagination driver. By adding this node, the kernel can recognize and initialize the GPU, providing graphics acceleration capabilities on the Lichee Pi 4A and other boards based on the TH1520 SoC. The display controller and HDMI output are still a work in progress. Also included is a MAINTAINERS patch that adds an entry for the T-Head SoC patchwork. Signed-off-by: Drew Fustini <fustini@kernel.org>
T-HEAD clock changes for v6.18
Updates for the T-HEAD TH1520 clock controller:
- Describe gate clocks with clk_gate so that clock gates can be clock
parents. This is similar to the mux clock refactor in 54edba916e29
("clk: thead: th1520-ap: Describe mux clocks with clk_mux").
- Add support for enabling/disabling PLLs. Some PLLs are put into a
disabled state by the bootloader, and clock driver now has the
ability to enable them.
- Set all AXI clocks to CLK_IS_CRITICAL. The AXI crossbar of TH1520 has
no proper timeout handling, which means gating AXI clocks can easily
lead to bus timeout and hang the system. All these clock gates are
ungated by default on system reset.
- Convert all current CLK_IGNORE_UNUSED usage to CLK_IS_CRITICAL to
prevent unwanted clock gating.
- Fix parent of padctrl0 clock, fix parent of DPU pixel clocks and
support changing DPU pixel clock rate.
All changes have been tested in linux-next.

Hi Will, Peter and Mark, I'm sending this pull request containing Rust atomic changes to tip tree. You can find the technical details below, but most importantly we got a new reviewer for ATOMIC INFRASTRUCTURE that can help maintaining the code. Welcome Gary! Similar to other pull requests of myself to the tip tree, this pull request is sent in form as patch series as well, in case that I missed something and changes are needed in some patch. Thanks! Rust atomic changes for v6.18: - Add initial support for generic LKMM atomic variables in Rust. This ensures Rust and C side are using the same memory model when communicating with each other, and would unblock a few more fine-grained concurrent core on Rust side. - Add the wrapper for `refcount_t` in Rust. This avoids using customized reference counting solution on Rust side (e.g. in `block::mq`). -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEj5IosQTPz8XU1wRHSXnow7UH+rgFAmi6YvwACgkQSXnow7UH +rh/kgf+LruO9gn49QAzDE4T7kf9rP/z4ocie8sxMtED5J0vw12PAVa0UERQyB4m 756O0GSFKwESJMjLUifBslkt64k8x8hQ+XHYH/WPe/Rm7Ku4kf1zsTO9Mt0xA5qr c5OgnLxR3T2L+1x8rEus8lPnExyX0G0b1/H1XjR+rvZAP1enwcLNyGFV3fNfAYNJ cMpkGCMFM9wc5dpzDx89ttw49I8yuy+Cmf/eTtm1YDWQgzYVEycF8jTkFqYykIax jMcZC0a1Lqrn1pLbxCZ5UEM9vxJREv46xBW6iKSkH5RWlbLo2gqMJbixYvkLtgBP AbtrUtsyIx4Rw0nPEZ880Nce/LdhUw== =Kuix -----END PGP SIGNATURE-----
Hi Miguel,
All commits have been in linux-next for a couple of weeks. There are two tr=
ivial
conflicts with the -mm and Linus' tree [1][2].
Some patches that would usually go through this tree went through the -mm t=
ree
[3][4]; [5] and [6] go through drm-rust together with their first user -- o=
ne
minor import conflict in samples/rust/rust_dma.rs expected.

Alloc & DMA changes for v6.18
Allocator:
- Provide information about the minimum alignment guarantees of
Kmalloc, Vmalloc and KVmalloc.
- Take minimum alignment guarantees of allocators for ForeignOwnable
into account.
- Remove the `allocator_test` incl. `Cmalloc`.
Box:
- Implement Box::pin_slice(), which constructs a pinned slice of
elements.
Vec:
- Simplify KUnit test module name to "rust_kvec".
- Add doc-test for Vec::as_slice().
- Constify various methods.
DMA:
- Update ARef and AlwaysRefCounted imports.
MISC:
- Remove support for unused host `#[test]`s.
- Constify ArrayLayout::new_unchecked().

Early Nuvoton arm64 devicetree updates for 6.18 Integrate changes from Tomer reworking devicetree pinctrl, reset, and clk n= odes for NPCM845-based platforms.
Early Nuvoton ARM devicetree updates for 6.18 So far we have just the one fix from Krzysztof that switches some nodes to = use generic names, as recommended by the spec.
Early ASPEED driver updates for 6.18 Two small changes, the most interesting being the addition of the silicon I= Ds for ASPEED's AST2700 SoC family.
Early ASPEED devicetree updates for 6.18 Notable changes: - Meta's Wedge400 and Fuji boards have had parallel devicetrees added for a transition to a new static flash layout. The original layout is deprecate= d and I anticipate removing related devicetrees in future releases. New platforms: - Darwin (Meta) Darwin is Meta's rack switch platform with an AST2600 BMC integrated for health monitoring purpose. Updates and fixes: - GB200NVL (Nvidia): Networking, I2C, regulators, GPIOs - Wedge400, Fuji (Meta): Fix warnings from devicetree bindings - Use fixed-layout for NVMEM on Asrock platforms - Various: minor fixes for warnings from FSI devicetree bindings
Hi Arnd, Here's our first very early pull request for the 6.18 merge window. All of these changes could've been part of the 6.17 window but the dt-binding changes were only picked up after I had already sent out my pull request which was already very late. These have been part -next for about a week now. Best, Sven Apple SoC device tree changes for v6.18, part 1 - Added SMC nodes for M1 and M2 including the PMU GPIO controller and reboot sub-nodes. This now allows to reboot these systems and is required to later enable the power GPIO line for the WiFi board. - Added i2c nodes for A7 - A11 SoCs Signed-off-by: Sven Peter <sven@kernel.org>
