[GIT PULL] NVMe changes for 4.5-rc1

[Jens Axboe]

Hi Linus,

Last branch for this series is the nvme changes. It's in a separate
branch to avoid splitting too much between core and NVMe changes, since
NVMe is still helping drive some blk-mq changes. That said, not a huge
amount of core changes in here. The grunt of the work is the continued
split of the code.

Note that pulling this in will conflict with master, since the code was
forked off pretty early, and we had a good chunk of nvme fixes later in
the 4.4 cycle.

Please pull!
