[PATCH 16/20] sh: use generic show_mem()

From: Johannes Weiner
Date: Fri Jun 27 2008 - 08:17:47 EST


Remove arch-specific show_mem() in favor of the generic version.

This also removes the following redundant information display:

- free pages, printed by show_free_areas()
- pages in slab, printed by show_free_areas()
- free swap pages, printed by show_swap_cache_info()
- pages in swapcache, printed by show_swap_cache_info()

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