I think it is worth discussing to add a flush() function to the
IOMMU-API. I sent a patch-set myself a few years ago introducing an
iommu_commit() function with the same semantics, but this is
out-of-scope for this patch-set.
Also adding a flag parameter to iommu_map_sg would introduce an
asymentrie in the API to the iommu_map() function. So please leave it
out for this patch-set, when we really need a flag parameter someday we
can introduce it for iommu_map() and iommu_map_sg() together.
