Since we leave tick_nohz_idle_exit() unchanged, can we keep 
tick_nohz_idle_prepare()
under the name tick_nohz_idle_enter() so that we stay symetric? And then make 
xen call
the two functions:

    tick_nohz_idle_enter();
    tick_nohz_idle_go_idle();

Also can we rename tick_nohz_idle_go_idle() to tick_nohz_idle_stop_tick() ?
This will be more self-explanatory.

Thanks.
