Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas: "The major features are support for LPA2 (52-bit VA/PA with 4K and 16K pages), the dpISA extension and Rust enabled on arm64. The changes are mostly contained within the usual arch/arm64/, drivers/perf, the arm64 Documentation and kselftests. The exception is the Rust support which touches some generic build files. Summary: - Reorganise the arm64 kernel VA space and add support for LPA2 (at stage 1, KVM stage 2 was merged earlier) - 52-bit VA/PA address range with 4KB and 16KB pages - Enable Rust on arm64 - Support for the 2023 dpISA extensions (data processing ISA), host only - arm64 perf updates: - StarFive's StarLink (integrates one or more CPU cores with a shared L3 memory system) PMU support - Enable HiSilicon Erratum 162700402 quirk for HIP09 - Several updates for the HiSilicon PCIe PMU driver - Arm CoreSight PMU support - Convert all drivers under drivers/perf/ to use .remove_new() - Miscellaneous: - Don't enable workarounds for "rare" errata by default - Clean up the DAIF flags handling for EL0 returns (in preparation for NMI support) - Kselftest update for ptrace() - Update some of the sysreg field definitions - Slight improvement in the code generation for inline asm I/O accessors to permit offset addressing - kretprobes: acquire regs via a BRK exception (previously done via a trampoline handler) - SVE/SME cleanups, comment updates - Allow CALL_OPS+CC_OPTIMIZE_FOR_SIZE with clang (previously disabled due to gcc silently ignoring -falign-functions=N)" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (134 commits) Revert "mm: add arch hook to validate mmap() prot flags" Revert "arm64: mm: add support for WXN memory translation attribute" Revert "ARM64: Dynamically allocate cpumasks and increase supported CPUs to 512" ARM64: Dynamically allocate cpumasks and increase supported CPUs to 512 kselftest/arm64: Add 2023 DPISA hwcap test coverage kselftest/arm64: Add basic FPMR test kselftest/arm64: Handle FPMR context in generic signal frame parser arm64/hwcap: Define hwcaps for 2023 DPISA features arm64/ptrace: Expose FPMR via ptrace arm64/signal: Add FPMR signal handling arm64/fpsimd: Support FEAT_FPMR arm64/fpsimd: Enable host kernel access to FPMR arm64/cpufeature: Hook new identification registers up to cpufeature docs: perf: Fix build warning of hisi-pcie-pmu.rst perf: starfive: Only allow COMPILE_TEST for 64-bit architectures MAINTAINERS: Add entry for StarFive StarLink PMU docs: perf: Add description for StarFive's StarLink PMU dt-bindings: perf: starfive: Add JH8100 StarLink PMU perf: starfive: Add StarLink PMU support docs: perf: Update usage for target filter of hisi-pcie-pmu ...
