[PATCH v3 3/10] x86/asm: Fix pud/pmd interfaces to handle large PAT bit

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 ar
