This code adds VM and VCPU setup code for the VM_MODE_FLAT48PG mode. The VM_MODE_FLAT48PG isn't yet fully supportable, as it defines the guest physical address limit as 52-bits, and KVM currently only supports guests with up to 40-bit physical addresses (see KVM_PHYS_SHIFT). VM_MODE_FLAT48PG will work fine, though, as long as no >= 40-bit physical addresses are used. Signed-off-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
