    x86: mm: restore original pte_special check · c819f37e
    Mel Gorman 提交于
    Commit b38af472 ("x86,mm: fix pte_special versus pte_numa") adjusted
    the pte_special check to take into account that a special pte had
    SPECIAL and neither PRESENT nor PROTNONE.  Now that NUMA hinting PTEs
    are no longer modifying _PAGE_PRESENT it should be safe to restore the
    original pte_special behaviour.
