x86/mm: Fix page table dump to show PAT bit
/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.
