[GIT PULL] last minute NVMe fixes for 4.13

[Christoph Hellwig]

Hi Jens,

three more fixes for 4.13 below:

 - fix the incorrect bit for the doorbell buffer features (Changpeng Liu)
 - always use a 4k MR page size for RDMA, to not get in trouble with
   offset in non-4k page size systems (no-op for x86) (Max Gurtovoy)
 - and a fix for the new nvme host memory buffer support to keep the
   descriptor list DMA mapped when the buffer is enabled (me)

The following changes since commit e9d8a0fdeacd843c85dcef480cdb2ab76bcdb6e4:

  nvme-pci: set cqe_seen on polled completions (2017-08-18 09:19:39 +0200)

are available in the git repository at:

  git://git.infradead.org/nvme.git nvme-4.13
