    The only thing NO_IDLE_HZ=y "forces" on other users is some extra code
    (which you are going to get no matter what with CONFIG_PARAVIRT). It
    doesn't force them to use this code. It just provides a few extra
    routines that a paravirt_ops backend might want to call back into (I
    think both vmi and xen backends use these routines and that is why it
    became associated with CONFIG_PARAVIRT rather than CONFIG_VMI).
