- Move the sysctl initialization code into spectre.c. This way each variable is local. Rename the variables, use shorter names. - Use mitigation methods for SpectreV4, like SpectreV2. There are several available on AMD (that we don't support yet). Add a "method" leaf. - Make SSB_NO a mitigation method by itself. This way we report as "mitigated" a CPU that is not affected by SpectreV4. In this case, of course, the user can't enable/disable the mitigation. Drop the "affected" sysctl leaf.
