[PATCH 5/5] mm, hmm: mark hmm_devmem_{add, add_resource} EXPORT_SYMBOL_GPL

[Dan Williams <dan.j.williams@intel.com>]

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().
