    Subject[PATCH 12/20] powerpc: use generic show_mem()
    Remove arch-specific show_mem() in favor of the generic version.

    This also removes the following redundant information display:

    - pages in swapcache, printed by show_swap_cache_info()

    where show_mem() calls show_free_areas(), which calls
    show_swap_cache_info().
