src/sys/arch/x86/x86: spectre.c x86_machdep.c
Log Message:
Several changes:
- 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.
