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).
