Right now, the set of features that are stored in the VMSA upon initialization is fixed and depends on the module parameters for kvm-amd.ko. However, the hypervisor cannot really change it at will because the feature word has to match between the hypervisor and whatever computes a measurement of the VMSA for attestation purposes. Add a field to kvm_sev_info that holds the set of features to be stored in the VMSA; and query it instead of referring to the module parameters. Because KVM_SEV_INIT and KVM_SEV_ES_INIT accept no parameters, this does not yet introduce any functional change, but it paves the way for an API that allows customization of the features per-VM.
