In particular, it is never selected by default since it has the lowest rating of all governors (menu=3D20, teo=3D19, ladder=3D10/25, haltpoll=3D9). So, we can safely forgo the kvm_para_available() check. This also allows cpuidle-haltpoll to be tested on baremetal. Signed-off-by: Joao Martins Signed-off-by: Mihai Carabas Acked-by: Rafael J.
