[PATCH RFC v9 23/51] KVM: SEV: Select CONFIG_KVM_PROTECTED_VM when CONFIG_KVM_AMD_SEV=y

[Michael Roth]

AMD SEV relies on the restricted/protected memory support to run guests
in some cases (such as SEV lazy-pinning), so make sure to enable that
support with the CONFIG_KVM_PROTECTED_VM build option.
