Merge branch 'nvme-4.13' of git://git.infradead.org/nvme into for-4.13/block 

Pull NVMe changes for 4.13 from Christoph:

Highlights:

 - UUID identifier support from Johannes
 - Lots of cleanups from Sagi
 - Host Memory Buffer support from me

And lots of cleanups and smaller fixes of course.

Note that the UUID identifier changes are based on top of the uuid tree.
I am the maintainer of that tree and will send it to Linus as soon as
4.12 is released as various other trees depend on it as well (and the
diffstat includes those changes unfortunately)
