git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 updates from Will Deacon: "The headline feature is the re-enablement of support for Arm's Scalable Matrix Extension (SME) thanks to a bumper crop of fixes from Mark Rutland. If matrices aren't your thing, then Ryan's page-table optimisation work is much more interesting. Summary: 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 Entry code: - Hook up TIF_NEED_RESCHED_LAZY so that CONFIG_PREEMPT_LAZY can be selected Memory management: - Prevent BSS exports from being used by the early PI code - Propagate level and stride information to the low-level TLB invalidation routines when operating on hugetlb entries - Use the page-table contiguous hint for vmap() mappings with VM_ALLOW_HUGE_VMAP where possible - Optimise vmalloc()/vmap() page-table updates to use "lazy MMU mode" and hook this up on arm64 so that the trailing DSB (used to publish the updates to the hardware walker) can be deferred until the end of the mapping operation - Extend mmap() randomisation for 52-bit virtual addresses (on par with 48-bit addressing) and remove limited support for randomisation of the linear map Perf and PMUs: - Add support for probing the CMN-S3 driver using ACPI - Minor driver fixes to the CMN, Arm-NI and amlogic PMU drivers Selftests: - Fix FPSIMD and SME tests to align with the freshly re-enabled SME support - Fix default setting of the OUTPUT variable so that tests are installed in the right location vDSO: - Replace raw counter access from inline assembly code with a call to the the __arch_counter_get_cntvct() helper function Miscellaneous: - Add some missing header inclusions to the CCA headers - Rework rendering of /proc/cpuinfo to follow the x86-approach and avoid repeated buffer expansion (the user-visible format remains identical) - Remove redundant selection of CONFIG_CRC32 - Extend early error message when failing to map the device-tree blob" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (83 commits) arm64: cputype: Add cputype definition for HIP12 arm64: el2_setup.h: Make __init_el2_fgt labels consistent, again perf/arm-cmn: Add CMN S3 ACPI binding arm64/boot: Disallow BSS exports to startup code arm64/boot: Move global CPU override variables out of BSS arm64/boot: Move init_pgdir[] and init_idmap_pgdir[] into __pi_ namespace perf/arm-cmn: Initialise cmn->cpu earlier kselftest/arm64: Set default OUTPUT path when undefined arm64: Update comment regarding values in __boot_cpu_mode arm64: mm: Drop redundant check in pmd_trans_huge() arm64/mm: Re-organise setting up FEAT_S1PIE registers PIRE0_EL1 and PIR_EL1 arm64/mm: Permit lazy_mmu_mode to be nested arm64/mm: Disable barrier batching in interrupt contexts arm64/cpuinfo: only show one cpu's info in c_show() arm64/mm: Batch barriers when updating kernel mappings mm/vmalloc: Enter lazy mmu mode while manipulating vmalloc ptes arm64/mm: Support huge pte-mapped pages in vmap mm/vmalloc: Gracefully unmap huge ptes mm/vmalloc: Warn on improper use of vunmap_range() arm64/mm: Hoist barriers out of set_ptes_anysz() loop ...

git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup Pull cgroup updates from Tejun Heo: - cgroup rstat shared the tracking tree across all controllers with the rationale being that a cgroup which is using one resource is likely to be using other resources at the same time (ie. if something is allocating memory, it's probably consuming CPU cycles). However, this turned out to not scale very well especially with memcg using rstat for internal operations which made memcg stat read and flush patterns substantially different from other controllers. JP Kobryn split the rstat tree per controller. - cgroup BPF support was hooking into cgroup init/exit paths directly.

2025-05-27ipe: add errno field to IPE policy load auditingJasjiv Singh
Users of IPE require a way to identify when and why an operation fails, allowing them to both respond to violations of policy and be notified of potentially malicious actions on their systems with respect to IPE. This patch introduces a new error field to the AUDIT_IPE_POLICY_LOAD event to log policy loading failures. Currently, IPE only logs successful policy loads, but not failures. Tracking failures is crucial to detect malicious attempts and ensure a complete audit trail for security events. The new error field will capture the following error codes: * -ENOKEY: Key used to sign the IPE policy not found in the keyring * -ESTALE: Attempting to update an IPE policy with an older version * -EKEYREJECTED: IPE signature verification failed * -ENOENT: Policy was deleted while updating * -EEXIST: Same name policy already deployed * -ERANGE: Policy version number overflow * -EINVAL: Policy version parsing error * -EPERM: Insufficient permission * -ENOMEM: Out of memory (OOM) * -EBADMSG: Policy is invalid Here are some examples of the updated audit record types: AUDIT_IPE_POLICY_LOAD(1422): audit: AUDIT1422 policy_name="Test_Policy" policy_version=0.0.1 policy_digest=sha256:84EFBA8FA71E62AE0A537FAB962F8A2BD1053964C4299DCA 92BFFF4DB82E86D3 auid=1000 ses=3 lsm=ipe res=1 errno=0 The above record shows a new policy has been successfully loaded into the kernel with the policy name, version, and hash with the errno=0. AUDIT_IPE_POLICY_LOAD(1422) with error: audit: AUDIT1422 policy_name=? policy_version=? policy_digest=? auid=1000 ses=3 lsm=ipe res=0 errno=-74 The above record shows a policy load failure due to an invalid policy (-EBADMSG). By adding this error field, we ensure that all policy load attempts, whether successful or failed, are logged, providing a comprehensive audit trail for IPE policy management.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "Once again, the changes are dominated by cpufreq updates, but this time the majority of them are cpufreq core changes, mostly related to the introduction of policy locking guards and __free() usage, and fixes related to boost handling. Still, there is also a significant update of the intel_pstate driver making it register an energy model when running on a hybrid platform which is used for enabling energy-aware scheduling (EAS) if the driver operates in the passive mode (and schedutil is used as the cpufreq governor for all CPUs which is the passive mode default). There are some amd-pstate driver updates too, for a good measure, including the "Requested CPU Min frequency" BIOS option support and new online/offline callbacks. In the cpuidle space, the most significant change is the addition of a C1 demotion on/off sysfs knob to intel_idle which should help some users to configure their systems more precisely. There is also the conversion of the PSCI cpuidle driver to a faux device one and there are two small updates of cpuidle governors. Device power management is also modified quite a bit, especially the handling of devices with asynchronous suspend and resume enabled during system transitions.

Pull documentation updates from Jonathan Corbet: "A moderately busy cycle for documentation this time around: - The most significant change is the replacement of the old kernel-doc script (a monstrous collection of Perl regexes that predates the Git era) with a Python reimplementation. That, too, is a horrifying collection of regexes, but in a much cleaner and more maintainable structure that integrates far better with the Sphinx build system. This change has been in linux-next for the full 6.15 cycle; the small number of problems that turned up have been addressed, seemingly to everybody's satisfaction. The Perl kernel-doc script remains in tree (as scripts/kernel-doc.pl) and can be used with a command-line option if need be. Unless some reason to keep it around materializes, it will probably go away in 6.17.

People will never understand that APIs exist for a reason... - Provide core infrastructre for the upcoming PCI endpoint library extensions. Currently limited to ARM GICv3+, but in theory extensible to other architectures. - Provide a MSI domain::teardown() callback, which allows drivers to undo the effects of the prepare() callback. - Move the MSI domain::prepare() callback invocation to domain creation time to avoid redundant (and in case of ARM/GIC-V3-ITS confusing) invocations on every allocation. In combination with the new teardown callback this removes some ugly hacks in the GIC-V3-ITS driver, which pretended to work around the short comings of the core code so far. With this update the code is correct by design and implementation. - Make the irqchip MSI library globally available, provide a MSI parent domain creation helper and convert a bunch of (PCI/)MSI drivers over to the modern MSI parent mechanism.
