diff --cc arch/arm64/include/asm/mman.h index 798d965760d4,1dbfb56cb313..e1572482fae8 --- a/arch/arm64/include/asm/mman.h
Hi Linus, Here are the arm64 updates for 6.13. The major features are support to run Linux in a protected VM (a.k.a. realm) under the Arm CCA and the user Guarded Control Stack (GCS). There are a few smaller scale additions for in-kernel memcpy instructions, MTE hugetlbfs support, optimised CRC32, non-leaf pmd_young(), the usual perf/PMU updates and various fixes and cleanups. We are also introducing HWCAP3 as we'll likely run out of HWCAP2 bits in a year or so. There's a trivial conflict with mainline due to a recent upstream fix: commit 5baf8b037deb ("mm: refactor arch_calc_vm_flag_bits() and arm64 MTE handling") and the MTE hugetlbfs support. My fixup: +++ b/arch/arm64/include/asm/mman.h @@@ -42,7 -39,7 +42,7 @@@ static inline unsigned long arch_calc_v * filesystem supporting MTE (RAM-based). */ if (system_supports_mte() && - ((flags & MAP_ANONYMOUS) || shmem_file(file))) - (flags & (MAP_ANONYMOUS | MAP_HUGETLB))) ++ ((flags & (MAP_ANONYMOUS | MAP_HUGETLB)) || shmem_file(file))) return VM_MTE_ALLOWED; return 0; Depending on the order you pull other requests in, there are a couple more conflicts with the trace and KVM trees. The slightly more complicated one is in arch/arm64/kvm/guest.c - the MTE hugetlbfs support in the arm64 tree conflicting with the __gfn_to_page() use in kvm_vm_ioctl_mte_copy_tags() from the KVM tree. The resolution in -next is correct. Since the arm64 tree has two bases, -rc1 mostly but -rc3 for the perf branch, the diffstat below is generated against 6.12. Thanks. The following changes since commit 2e8a1acea8597ff42189ea94f0a63fa58640223d: arm64: signal: Improve POR_EL0 handling to avoid uaccess failures (2024-10-29 17:59:12 +0000) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-upstream for you to fetch changes up to 83ef4a378e563d085ddd7214c2a393116b5f3435: Merge branch 'for-next/pkey-signal' into for-next/core (2024-11-14 12:07:30 +0000) ---------------------------------------------------------------- arm64 updates for 6.13: * Support for running Linux in a protected VM under the Arm Confidential Compute Architecture (CCA) * Guarded Control Stack user-space support. Current patches follow the x86 ABI of implicitly creating a shadow stack on clone(). Subsequent patches (already on the list) will add support for clone3() allowing finer-grained control of the shadow stack size and placement from libc * AT_HWCAP3 support (not running out of HWCAP2 bits yet but we are getting close with the upcoming dpISA support) * Other arch features: - In-kernel use of the memcpy instructions, FEAT_MOPS (previously only exposed to user; uaccess support not merged yet) - MTE: hugetlbfs support and the corresponding kselftests - Optimise CRC32 using the PMULL instructions - Support for FEAT_HAFT enabling ARCH_HAS_NONLEAF_PMD_YOUNG - Optimise the kernel TLB flushing to use the range operations - POE/pkey (permission overlays): further cleanups after bringing the signal handler in line with the x86 behaviour for 6.12 * arm64 perf updates: - Support for the NXP i.MX91 PMU in the existing IMX driver - Support for Ampere SoCs in the Designware PCIe PMU driver - Support for Marvell's 'PEM' PCIe PMU present in the 'Odyssey' SoC - Support for Samsung's 'Mongoose' CPU PMU - Support for PMUv3.9 finer-grained userspace counter access control - Switch back to platform_driver::remove() now that it returns 'void' - Add some missing events for the CXL PMU driver * Miscellaneous arm64 fixes/cleanups: - Page table accessors cleanup: type updates, drop unused macros, reorganise arch_make_huge_pte() and clean up pte_mkcont(), sanity check addresses before runtime P4D/PUD folding - Command line override for ID_AA64MMFR0_EL1.ECV (advertising the FEAT_ECV for the generic timers) allowing Linux to boot with firmware deployments that don't set SCTLR_EL3.ECVEn - ACPI/arm64: tighten the check for the array of platform timer structures and adjust the error handling procedure in gtdt_parse_timer_block() - Optimise the cache flush for the uprobes xol slot (skip if no change) and other uprobes/kprobes cleanups - Fix the context switching of tpidrro_el0 when kpti is enabled - Dynamic shadow call stack fixes - Sysreg updates - Various arm64 kselftest improvements ---------------------------------------------------------------- Documentation/admin-guide/kernel-parameters.txt | 3 + Documentation/admin-guide/perf/index.rst | 1 + Documentation/admin-guide/perf/mrvl-pem-pmu.rst | 56 ++ Documentation/arch/arm64/arm-cca.rst | 69 ++ Documentation/arch/arm64/booting.rst | 38 ++ Documentation/arch/arm64/elf_hwcaps.rst | 10 +- Documentation/arch/arm64/gcs.rst | 227 +++++++ Documentation/arch/arm64/index.rst | 3 + Documentation/arch/arm64/mops.rst | 44 ++ Documentation/arch/arm64/sme.rst | 4 + Documentation/arch/arm64/sve.rst | 4 + Documentation/devicetree/bindings/arm/pmu.yaml | 1 + .../devicetree/bindings/perf/fsl-imx-ddr.yaml | 4 +- Documentation/filesystems/proc.rst | 2 +- MAINTAINERS | 6 + arch/arm/include/asm/arm_pmuv3.h | 8 + arch/arm64/Kconfig | 43 ++ arch/arm64/include/asm/arm_pmuv3.h | 10 + arch/arm64/include/asm/assembler.h | 7 -
