From: Joao Martins <joao.m.martins at oracle.com>
To test whether it's a guest or not for the default cases, the haltpoll
driver uses the kvm_para* helpers to find out if it's a guest or not.
ARM64 doesn't have or defined any of these, so it remains disabled on
the default. Although it allows to be force-loaded.
