[PATCH] KVM: VMX: Expose SSBD properly to guests.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The X86_FEATURE_SSBD is an synthetic CPU feature - that is
it bit location has no relevance to the real CPUID 0x7.EBX[31]
bit position. For that we need the new CPU feature name.

Fixes: 52817587e706 ("x86/cpufeatures: Disentangle SSBD enumeration")
