It is left out on purpose.
This patch is a stand-alone patch as it is. The other part of the series
you are talking about is not going to mainline for now. It needs still
quite some work, and will only go in after all the other printk stuff.
I hope we can merge this patch as it to mainline now, instead of piling
up more than necessary in the rt tree.
