Esto es necesario ya que las m\u00e1quinas virtuales ucontrol tienen kvm->arch.gmap establecido en 0 y, por lo tanto, dar\u00eda como resultado una desreferencia de puntero nulo m\u00e1s adelante. La administraci\u00f3n de la memoria debe realizarse en el espacio de usuario y utilizando los ioctls KVM_S390_UCAS_MAP y KVM_S390_UCAS_UNMAP.
