2ef9481e66 [PATCH] powerpc: trivial: modify comments to refer to new location of files
This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

a958a26486 [PATCH] powerpc: IOMMU SG paranoia
This addresses two items, which are unlikely to be hit if we
trust drivers.

The first is moving a memory barrier below where the vmerged SG count
is passed back, but before the list is set to end.  If those
instructions were reordered, there could be an issue in iommu_unmap_sg().

The second is making sure we terminate the list on the failure case of
iommu_map_sg().  If a driver does not look at the failure return code,
it could pass a ill-formed SG list to iommu_unmap_sg().

Also deletes files in arch/ppc64 that are no longer used now that
we don't compile with ARCH=ppc64 any more.
