    Subject[122/262] /proc/self/numa_maps: restore "huge" tag for hugetlb vmas
    3.0-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Andrew Morton <akpm@linux-foundation.org>

    commit fc360bd9cdcf875639a77f07fafec26699c546f3 upstream.

    The display of the "huge" tag was accidentally removed in 29ea2f698 ("mm:
    use walk_page_range() instead of custom page table walking code").
