The PAT bit gets relocated to bit 12 when PUD and PMD mappings are used. This bit 12, however, is not covered by PTE_FLAGS_MASK, which is corrently used for masking pfn and flags for all cases. Fix pud/pmd interfaces to handle pfn and flags properly by using P?D_PAGE_MASK when PUD/PMD mappings are used, i.e. PSE bit is set.
Can you please split that into a patch introducing and describing the new mask helper functions and a second one making use of it?
