linux-next: manual merge of the pci tree with the powerpc tree

[Stephen Rothwell]

Hi Bjorn,

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

  arch/powerpc/platforms/powernv/eeh-powernv.c

between commit:

  64ba3dc7bf7c ("powerpc/eeh: Update VF config space after EEH")

from the powerpc tree and commit:

  fdabc3fe9982 ("PCI: Add #defines for Completion Timeout Disable feature")

from the pci tree.

The former commit moved the code changed by the latter to another file.
I have added the following merge fix patch:

Subject: [PATCH] PCI: fix up for "powerpc/eeh: Update VF config space after EEH"

I fixed it up (see above) 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.
