It was never really useful, since the layering is fixed, and the current implementations do not need to call into parent implementations anyway. Each tag inherits its method table pointer and cookie from the parent (or the root tag) now, and the method wrapper macros directly use the method table of the tag. - Add a method table to the non-IOMMU backend, remove unnecessary prototypes, remove the extra parent tag argument. - Rename sparc64_dmamem_alloc_map() and sparc64_dmamem_free_map() to sparc64_dma_alloc_map() and sparc64_dma_free_map(), move them to a better place and use them for all map allocations and deallocations. - Add a method table to the iommu backend, and staticize functions, remove the extra parent tag argument. - Change the psycho and sbus drivers to just set cookie and method table in the root tag. - Miscellaneous small fixes.
