From: Joao Martins <joao.m.martins@xxxxxxxxxx>
The haltpoll governor is selected either by the cpuidle-haltpoll
driver, or explicitly by the user.
In particular, it is never selected by default since it has the lowest
rating of all governors (menu=20, teo=19, ladder=10/25, haltpoll=9).
So, we can safely forgo the kvm_para_available() check. This also
allows cpuidle-haltpoll to be tested on baremetal.
