Great!  I'll take a close look at your code soon.

I've use nvme_pci_* for any newly added PCI specific functions, and
we can slowly move the rest over once the split is done.  I'd prefer
to just use nvme_ for the core code.  While we're still working on
the split I'd prefer to avoid cosmetic renames for now.
