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

Hi Jesse,

Today's linux-next merge of the pci tree got a conflict in
arch/powerpc/include/asm/ppc-pci.h between commit cb3bc9d0de1e
("powerpc/eeh: Cleanup comments in the EEH core") from the powerpc tree
and commit 673c97562489 ("powerpc/PCI: replace pci_probe_only with
pci_flags") from the pci tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.

Cheers,
Stephen Rothwell                    sfr@...b.auug.org.au
