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

Hi all,

Today's linux-next merge of the iommufd tree got conflicts in:

  drivers/vfio/Kconfig
  drivers/vfio/Makefile

between commits:

  20601c45a0fa ("vfio: Remove CONFIG_VFIO_SPAPR_EEH")
  e2d55709398e ("vfio: Fold vfio_virqfd.ko into vfio.ko")

from the vfio tree and commits:

  a4d1f91db502 ("vfio-iommufd: Support iommufd for physical VFIO devices")
  e5a9ec7e096a ("vfio: Make vfio_container optionally compiled")
  c2849d718d26 ("vfio: Move vfio group specific code into group.c")

from the iommufd 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.
