[patch 22/22 -v3] xtensa: Use generic show_mem()

From: Johannes Weiner
Date: Mon Apr 07 2008 - 11:56:28 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 swapcache, printed by show_swap_cache_info()

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