  • 75980e97d   mm: fold page->_last_nid into page->flags where possible ... Browse Code »

    page->_last_nid fits into page->flags on 64-bit. The unlikely 32-bit
    NUMA configuration with NUMA Balancing will still need an extra page
    field. As Peter notes "Completely dropping 32bit support for
    CONFIG_NUMA_BALANCING would simplify things, but it would also remove
    the warning if we grow enough 64bit only page-flags to push the last-cpu
    out."

  • bbeae5b05   mm: move page flags layout to separate header ... Browse Code »

    This is a preparation patch for moving page->_last_nid into page->flags
    that moves page flag layout information to a separate header. This
    patch is necessary because otherwise there would be a circular
    dependency between mm_types.h and mm.h.
