From: Toshi Kani <toshi.kani@xxxxxxx> commit f70abb0fc3da1b2945c92751ccda2744081bf2b7 upstream. Now that we have pud/pmd mask interfaces, which handle pfn & flags mask properly for the large PAT bit. Fix pud/pmd pfn & flags interfaces by replacing PTE_PFN_MASK and PTE_FLAGS_MASK with the pud/pmd mask interfaces.
