   ### Mitigation B: Intel IBRS
   
   SpectreV2 can be mitigated with the IBRS method (Intel only for now). If
   the CPU supports this method, it is used automatically. It can be
   dynamically disabled by changing the "machdep.spectre_v2.mitigated"
   sysctl.
   
   ### Mitigation C: AMD DIS_IND
   
   SpectreV2 can be mitigated with the DIS_IND method, available only on a
   few AMD families. If the CPU supports this method, it is used
   automatically. It can be dynamically disabled by changing the
   "machdep.spectre_v2.mitigated" sysctl.
