Log message:
Newer ARMv8 processors now include a new CSV2 field in their processor
feature register that can indicate that a processor is not vulnarable to
Spectre v2 attacks. Use this field in favour of adding specific processors
to a whitelist. Continue to whitelist the few processors that are known
not to be vulnerable but don't set the appropriate value in the CSV2 field.
