[PATCH 05/20] blackfin: use generic show_mem()

[Johannes Weiner <hannes@saeurebad.de>]

[-- Attachment #1: 0006-blackfin-use-generic-show_mem.patch --]
[-- Type: text/plain, Size: 1712 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 swapcache, printed by show_swap_cache_info()

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