Mel Gorman 25cbbef192 mm: numa: Trap pmd hinting faults only if we would otherwise trap PTE faults
Base page PMD faulting is meant to batch handle NUMA hinting faults from
PTEs. However, even is no PTE faults would ever be handled within a
range the kernel still traps PMD hinting faults. This patch avoids the
overhead.
