Subject: linux-next: manual merge of the vfio tree with the kvms390 tree

Hi all,

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

  include/linux/vfio_pci_core.h

between commits:

  b6a7066f4e9b ("vfio/pci: introduce CONFIG_VFIO_PCI_ZDEV_KVM")
  6518ebc68c72 ("vfio-pci/zdev: add open/close device hooks")

from the kvms390 tree and commit:

  d1877e639bc6 ("vfio: de-extern-ify function prototypes")

from the vfio tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
