Allocate a page during vCPU creation to be used as the encrypted VM save area (VMSA) for the SEV-ES guest. Provide a flag in the kvm_vcpu_arch structure that indicates whether the guest state is protected. When freeing a VMSA page that has been encrypted, the cache contents must be flushed using the MSR_AMD64_VM_PAGE_FLUSH before freeing the page. [ i386 build warnings ] Reported-by:
