Fix and subsequently rewrite Spectre mitigations, including the addition of support for PR_SPEC_DISABLE_NOEXEC. (Will Deacon and Marc Zyngier) * for-next/ghostbusters: (22 commits) arm64: Add support for PR_SPEC_DISABLE_NOEXEC prctl() option arm64: Pull in task_stack_page() to Spectre-v4 mitigation code KVM: arm64: Allow patching EL2 vectors even with KASLR is not enabled arm64: Get rid of arm64_ssbd_state KVM: arm64: Convert ARCH_WORKAROUND_2 to arm64_get_spectre_v4_state() KVM: arm64: Get rid of kvm_arm_have_ssbd() KVM: arm64: Simplify handling of ARCH_WORKAROUND_2 arm64: Rewrite Spectre-v4 mitigation code arm64: Move SSBD prctl() handler alongside other spectre mitigation code arm64: Rename ARM64_SSBD to ARM64_SPECTRE_V4 arm64: Treat SSBS as a non-strict system feature arm64: Group start_thread() functions together KVM: arm64: Set CSV2 for guests on hardware unaffected by Spectre-v2 arm64: Rewrite Spectre-v2 mitigation code arm64: Introduce separate file for spectre mitigations and reporting arm64: Rename ARM64_HARDEN_BRANCH_PREDICTOR to ARM64_SPECTRE_V2 KVM: arm64: Simplify install_bp_hardening_cb() KVM: arm64: Replace CONFIG_KVM_INDIRECT_VECTORS with CONFIG_RANDOMIZE_BASE arm64: Remove Spectre-related CONFIG_* options arm64: Run ARCH_WORKAROUND_2 enabling code on all CPUs ...
