Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon: "There's a reasonable amount here and the juicy details are all below. It's worth noting that the MTE/KASAN changes strayed outside of our usual directories due to core mm changes and some associated changes to some other architectures; Andrew asked for us to carry these [1] rather that take them via the -mm tree. Summary: - Optimise SVE switching for CPUs with 128-bit implementations. - Fix output format from SVE selftest. - Add support for versions v1.2 and 1.3 of the SMC calling convention. - Allow Pointer Authentication to be configured independently for kernel and userspace. - PMU driver cleanups for managing IRQ affinity and exposing event attributes via sysfs. - KASAN optimisations for both hardware tagging (MTE) and out-of-line software tagging implementations. - Relax frame record alignment requirements to facilitate 8-byte alignment with KASAN and Clang. - Cleanup of page-table definitions and removal of unused memory types. - Reduction of ARCH_DMA_MINALIGN back to 64 bytes. - Refactoring of our instruction decoding routines and addition of some missing encodings. - Move entry code moved into C and hardened against harmful compiler instrumentation. - Update booting requirements for the FEAT_HCX feature, added to v8.7 of the architecture. - Fix resume from idle when pNMI is being used. - Additional CPU sanity checks for MTE and preparatory changes for systems where not all of the CPUs support 32-bit EL0. - Update our kernel string routines to the latest Cortex Strings implementation. - Big cleanup of our cache maintenance routines, which were confusingly named and inconsistent in their implementations. - Tweak linker flags so that GDB can understand vmlinux when using RELR relocations. - Boot path cleanups to enable early initialisation of per-cpu operations needed by KCSAN. - Non-critical fixes and miscellaneous cleanup" * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (150 commits) arm64: tlb: fix the TTL value of tlb_get_level arm64: Restrict undef hook for cpufeature registers arm64/mm: Rename ARM64_SWAPPER_USES_SECTION_MAPS arm64: insn: avoid circular include dependency arm64: smp: Bump debugging information print down to KERN_DEBUG drivers/perf: fix the missed ida_simple_remove() in ddr_perf_probe() perf/arm-cmn: Fix invalid pointer when access dtc object sharing the same IRQ number arm64: suspend: Use cpuidle context helpers in cpu_suspend() PSCI: Use cpuidle context helpers in psci_cpu_suspend_enter() arm64: Convert cpu_do_idle() to using cpuidle context helpers arm64: Add cpuidle context save/restore helpers arm64: head: fix code comments in set_cpu_boot_mode_flag arm64: mm: drop unused __pa(__idmap_text_start) arm64: mm: fix the count comments in compute_indices arm64/mm: Fix ttbr0 values stored in struct thread_info for software-pan arm64: mm: Pass original fault address to handle_mm_fault() arm64/mm: Drop SECTION_[SHIFT|SIZE|MASK] arm64/mm: Use CONT_PMD_SHIFT for ARM64_MEMSTART_SHIFT arm64/mm: Drop SWAPPER_INIT_MAP_SIZE arm64: Conditionally configure PTR_AUTH key of the kernel. ...
