    Subject[PATCH v4 6/8] cpuidle-haltpoll: ARM64 support
    Date
    From: Joao Martins <joao.m.martins@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.
