/sys/kernel/debug/kernel_page_tables does not show the PAT bit for PUD/PMD mappings. This is because walk_pud_level(), walk_pmd_level() and note_page() mask the flags with PTE_FLAGS_MASK, which does not cover their PAT bit, _PAGE_PAT_LARGE. Fix it by replacing the use of PTE_FLAGS_MASK with p?d_flags(), which masks the flags properly. Also change to show the PAT bit as "PAT" to be consistent with other bits.
