Jake Moilanen 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().
