Hmm .. This doesn't look like it's taking into account that the time has
changed ..
Why? By the time it gets called (form the timer softirq context)
It is called from interrupt context at least in mainline. Only the -rt
patch moves this to the softirq.
Anyway, by the time it gets called, tb_last_jiffy gets updated.
