[patch 17/22 -v3] sh: Use generic show_mem()

[Johannes Weiner <hannes@saeurebad.de>]

[-- Attachment #1: sh-use-generic-show_mem.patch --]
[-- Type: text/plain, Size: 2322 bytes --]

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()
	- pages in swapcache, printed by show_swap_cache_info()

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