    arm64: Rewrite Spectre-v4 mitigation code · c2876207
    Will Deacon authored
    Rewrite the Spectre-v4 mitigation handling code to follow the same
    approach as that taken by Spectre-v2.
    
    For now, report to KVM that the system is vulnerable (by forcing
    'ssbd_state' to ARM64_SSBD_UNKNOWN), as this will be cleared up in
    subsequent steps.
