Merge branch 'for-next/cpufeature' into for-next/core
Support for overriding CPU ID register fields on the command-line, which allows us to disable certain features which the kernel would otherwise use unconditionally when detected. * for-next/cpufeature: (22 commits) 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 arm64: Initialise as nVHE before switching to VHE arm64: Provide an 'upgrade to VHE' stub hypercall arm64: Turn the MMU-on sequence into a macro ...
