Since there's some heartburn about the STIBP naming, should we make this
more generic?  Maybe something like "SMT hardening", so it says:

	"User space: Mitigation: SMT hardening via prctl"

or,

 	"User space: Mitigation: maybe go slow on indirect branches via prctl"

if we're trying be more precise on the effects. :)
