4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Williams <[email protected]> commit 800dc4f49cc002879e1e5e6b79926f86b60528e6 upstream. This reverts commit 22b14523994588279ae9c5ccfe64073c1e5b3c00. It was originally sent in an earlier revision of the pfn_t patchset. Besides being broken, the warning is also fixed by PFN_FLAGS_MASK casting the PAGE_MASK to an unsigned long.
