Keith,
What you actually are doing here is claiming copyright on code that other people have written, and tighten the export restrictions. kmap_atomic_prot_pfn() appeared long ago in drm git with identical code and purpose, but with different authors, and iounmap_atomic is identical to kunmap_atomic.
+EXPORT_SYMBOL_GPL(iomap_atomic_prot_pfn);
you want to use this facility in a binary-only driver?
