Similar to other large Intel features such as VMX and TXT, SGX must be
explicitly enabled in IA32_FEATURE_CONTROL MSR to be truly usable.
Clear all SGX related capabilities if SGX is not fully enabled in
IA32_FEATURE_CONTROL or if the SGX1 instruction set isn't
From: Sean Christopherson
Similar to other large Intel features such as VMX and TXT, SGX must be
explicitly enabled in IA32_FEATURE_CONTROL MSR to be truly usable.
Clear all SGX related capabilities if SGX is not fully enabled in
IA32_FEATURE_CONTROL or if the SGX1 instruction set isn't
