fsl_pamu is the last user of domain_alloc(), and it is using it to create something weird that doesn't really fit into the iommu subsystem architecture. It is a not a paging domain since it doesn't have any map/unmap ops. It may be some special kind of identity domain. For now just leave it as is. Wrap it's definition in CONFIG_FSL_PAMU to discourage any new drivers from attempting to use it. Signed-off-by: Jason Gunthorpe<jgg@xxxxxxxxxx>
