arm64: spectre: Rename ARM64_HARDEN_EL2_VECTORS to ARM64_SPECTRE_V3A
Since ARM64_HARDEN_EL2_VECTORS is really a mitigation for Spectre-v3a,
rename it accordingly for consistency with the v2 and v4 mitigation.

See the kern_hyp_va macro and kvm_update_va_mask function for more details. MMIO devices such as GICv2 gets mapped next to the HYP idmap page, as do vectors when -ARM64_HARDEN_EL2_VECTORS is selected for particular CPUs. +ARM64_SPECTRE_V3A is enabled for particular CPUs. When using KVM with the Virtualization Host Extensions, no additional mappings are created, since the host kernel runs directly in EL2. |
