The routines hmm_devmem_add(), and hmm_devmem_add_resource() are small wrappers around devm_memremap_pages(). The devm_memremap_pages() interface is a subset of the hmm functionality which has more and deeper ties into the kernel memory management implementation. It was an oversight that these symbols were not marked EXPORT_SYMBOL_GPL from the outset due to how they originally copied (and now reuse) devm_memremap_pages().
