    Subject[PATCH v3 2.6.39-rc1-tip 1/26] 1: mm: replace_page() loses static attribute

    User bkpt will use background page replacement approach to insert/delete
    breakpoints. Background page replacement approach is based on
    replace_page. Hence replace_page() loses its static attribute.
    This is a precursor to moving replace_page() to mm/memory.c
