| |
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() - dirty pages, writeback pages, mapped pages, slab pages, pagetables pages, printed by show_free_areas()
where show_mem() calls show_free_areas(), which calls show_swap_cache_info().
