linux-next: manual merge of the dt-rh tree with the iommu tree

[Stephen Rothwell]

Hi Rob,

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

  drivers/iommu/arm-smmu.c

between commit:

  d54663573131 ("iommu/arm-smmu: Use per-domain page sizes.")

from the iommu tree and commit:

  cb6c27bb0912 ("iommu/arm-smmu: Make use of phandle iterators in device-tree parsing")

from the dt-rh 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.

Sorry, I'll take partial responsibility for that, as I'd forgotten about 
the SMMU patch Rob was carrying when Joerg picked up my conflicting 
patches. The resolution looks fine to me.
