Subject: linux-next: manual merge of the net-next tree with the pci tree

Hi all,

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

  drivers/pci/Kconfig
  drivers/pci/controller/pci-hyperv.c

between commit:

  f58ba5e3f686 ("PCI: pci-hyperv: Fix build errors on non-SYSFS config")
  44b1ece783ff ("PCI: hv: Detect and fix Hyper-V PCI domain number collision")

from the pci tree and commit:

  348dd93e40c1 ("PCI: hv: Add a Hyper-V PCI interface driver for software backchannel interface")

from the net-next 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

            The PCI device frontend driver allows the kernel to import arbitrary
            PCI devices from a PCI backend to support PCI driver domains.
