Subject: linux-next: manual merge of the nvdimm tree with the v4l-dvb tree

Hi Dan,

Today's linux-next merge of the nvdimm tree got a conflict in:

  mm/Kconfig

between commit:

  8025e5ddf9c1 ("[media] mm: Provide new get_vaddr_frames() helper")

from the v4l-dvb tree and commit:

  033fbae988fc ("mm: ZONE_DEVICE for "device memory"")

from the nvdimm tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
