    tick/timekeeping: Call update_wall_time outside the jiffies lock · 47a1b796
    John Stultz authored
    Since the xtime lock was split into the timekeeping lock and
    the jiffies lock, we no longer need to call update_wall_time()
    while holding the jiffies lock.
    
    Thus, this patch splits update_wall_time() out from do_timer().
    
    This allows us to get away from calling clock_was_set_delayed()
    in update_wall_time() and instead use the standard clock_was_set()
    call that previously would deadlock, as it causes the jiffies lock
    to be acquired.
