Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon: - vDSO build improvements including support for building with BSD. - Cleanup to the AMU support code and initialisation rework to support cpufreq drivers built as modules. - Removal of synthetic frame record from exception stack when entering the kernel from EL0. - Add support for the TRNG firmware call introduced by Arm spec DEN0098. - Cleanup and refactoring across the board. - Avoid calling arch_get_random_seed_long() from add_interrupt_randomness() - Perf and PMU updates including support for Cortex-A78 and the v8.3 SPE extensions. - Significant steps along the road to leaving the MMU enabled during kexec relocation. - Faultaround changes to initialise prefaulted PTEs as 'old' when hardware access-flag updates are supported, which drastically improves vmscan performance. - CPU errata updates for Cortex-A76 (#1463225) and Cortex-A55 (#1024718) - Preparatory work for yielding the vector unit at a finer granularity in the crypto code, which in turn will one day allow us to defer softirq processing when it is in use. - Support for overriding CPU ID register fields on the command-line. * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (85 commits) drivers/perf: Replace spin_lock_irqsave to spin_lock mm: filemap: Fix microblaze build failure with 'mmu_defconfig' arm64: Make CPU_BIG_ENDIAN depend on ld.bfd or ld.lld 13.0.0+ arm64: cpufeatures: Allow disabling of Pointer Auth from the command-line arm64: Defer enabling pointer authentication on boot core arm64: cpufeatures: Allow disabling of BTI from the command-line arm64: Move "nokaslr" over to the early cpufeature infrastructure KVM: arm64: Document HVC_VHE_RESTART stub hypercall arm64: Make kvm-arm.mode={nvhe, protected} an alias of id_aa64mmfr1.vh=0 arm64: Add an aliasing facility for the idreg override arm64: Honor VHE being disabled from the command-line arm64: Allow ID_AA64MMFR1_EL1.VH to be overridden from the command line arm64: cpufeature: Add an early command-line cpufeature override facility arm64: Extract early FDT mapping from kaslr_early_init() arm64: cpufeature: Use IDreg override in __read_sysreg_by_encoding() arm64: cpufeature: Add global feature override facility arm64: Move SCTLR_EL1 initialisation to EL-agnostic code arm64: Simplify init_el2_state to be non-VHE only arm64: Move VHE-specific SPE setup to mutate_to_vhe() arm64: Drop early setting of MDSCR_EL2.TPMS ...
