    [PATCH] fix next_timer_interrupt() for hrtimer · 69239749

    Function next_timer_interrupt() got broken with a recent patch
    6ba1b912 as sys_nanosleep() was moved to
    hrtimer.  This broke things as next_timer_interrupt() did not check hrtimer
    tree for next event.
    
    Function next_timer_interrupt() is needed with dyntick (CONFIG_NO_IDLE_HZ,
    VST) implementations, as the system can be in idle when next hrtimer event
    was supposed to happen.  At least ARM and S390 currently use
    next_timer_interrupt().
