Subject: linux-next: manual merge of the vfio tree with the s390 tree

Hi all,

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

  arch/s390/pci/pci_bus.c

between commit:

  abb95b7550f8 ("s390/pci: consolidate SR-IOV specific code")

from the s390 tree and commit:

  08b6e22b850c ("s390/pci: Mark all VFs as not implementing PCI_COMMAND_MEMORY")

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,
