Nothing major, some left-overs from the recent merging window (MTE, coco) and some newly found issues like the ptrace() ones. More details in the tag. Thanks. The following changes since commit 40384c840ea1944d7c5a392e8975ed088ecf0b37: Linux 6.13-rc1 (2024-12-01 14:28:56 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux tags/arm64-fixes for you to fetch changes up to d60624f72d15862a96965b945f6ddfee9a1359e7: arm64: ptrace: fix partial SETREGSET for NT_ARM_GCS (2024-12-05 18:05:51 +0000) ---------------------------------------------------------------- arm64 fixes for 6.13-rc2: - MTE/hugetlbfs: - Set VM_MTE_ALLOWED in the arch code and remove it from the core code for hugetlbfs mappings - Fix copy_highpage() warning when the source is a huge page but not MTE tagged, taking the wrong small page path - drivers/virt/coco: - Add the pKVM and Arm CCA drivers under the arm64 maintainership - Fix the pkvm driver to fall back to ioremap() (and warn) if the MMIO_GUARD hypercall fails - Keep the Arm CCA driver default 'n' rather than 'm' - A series of fixes for the arm64 ptrace() implementation, potentially leading to the kernel consuming uninitialised stack variables when PTRACE_SETREGSET is invoked with a length of 0 - Fix zone_dma_limit calculation when RAM starts below 4GB and ZONE_DMA is capped to this limit - Fix early boot warning with CONFIG_DEBUG_VIRTUAL=y triggered by a call to page_to_phys() (from patch_map()) which checks pfn_valid() before vmemmap has been set up - Do not clobber bits 15:8 of the ASID used for TTBR1_EL1 and TLBI ops when the kernel assumes 8-bit ASIDs but running under a hypervisor on a system that implements 16-bit ASIDs (found running Linux under Parallels on Apple M4) - ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A as it is using the same SMMU PMCG as HIP09 and suffers from the same errata - Add GCS to cpucap_is_possible(), missed in the recent merge ---------------------------------------------------------------- Catalin Marinas (2): arm64: Ensure bits ASID[15:8] are masked out when the kernel uses 8-bit ASIDs arm64: mte: Fix copy_highpage() warning on hugetlb folios Mark Rutland (5): arm64: patching: avoid early page_to_phys() arm64: ptrace: fix partial SETREGSET for NT_ARM_TAGGED_ADDR_CTRL arm64: ptrace: fix partial SETREGSET for NT_ARM_FPMR arm64: ptrace: fix partial SETREGSET for NT_ARM_POE arm64: ptrace: fix partial SETREGSET for NT_ARM_GCS Qinxin Xia (1): ACPI/IORT: Add PMCG platform information for HiSilicon HIP09A Robin Murphy (1): arm64: cpufeature: Add GCS to cpucap_is_possible() Suzuki K Poulose (1): coco: virt: arm64: Do not enable cca guest driver by default Will Deacon (2): drivers/virt: pkvm: Don't fail ioremap() call if MMIO_GUARD fails MAINTAINERS: Add CCA and pKVM CoCO guest support to the ARM64 entry Yang Shi (2): arm64: mte: set VM_MTE_ALLOWED for hugetlbfs at correct place arm64: mm: Fix zone_dma_limit calculation Documentation/arch/arm64/silicon-errata.rst | 5 ++-- MAINTAINERS | 2 ++ arch/arm64/include/asm/cpucaps.h | 2 ++ arch/arm64/include/asm/cpufeature.h | 3 +-- arch/arm64/include/asm/mman.h | 3 ++- arch/arm64/kernel/patching.c | 21 +++++++--------- arch/arm64/kernel/ptrace.c | 36 +++++++++++++++++++++------ arch/arm64/mm/context.c | 4 +-- arch/arm64/mm/copypage.c | 8 +++--- arch/arm64/mm/init.c | 17 ++++++------- drivers/acpi/arm64/iort.c | 2 ++ drivers/virt/coco/arm-cca-guest/Kconfig | 1 - drivers/virt/coco/pkvm-guest/arm-pkvm-guest.c | 6 +---- fs/hugetlbfs/inode.c | 2 +- 14 files changed, 67 insertions(+), 45 deletions(-) -- Catalin
