Rebased on the current nvme/nvme-6.8 branch and added the Review tags. Also
addressed the printk format issue pointed out by Chaitanya.

About PI: I've added a note to the first commit pointing on this topic. I
understood from the discussion, that yes it is an issue but it already exists
and we will address this in future.

Thanks,
Daniel
