Subject: [PATCH 08/20] m32r: use generic show_mem()
Date: Fri, 27 Jun 2008 13:53:57 +0200	[thread overview]
Message-ID: <20080627120048.965282649@saeurebad.de> (raw)
In-Reply-To: 20080627115349.743368154@saeurebad.de

[-- Attachment #1: 0009-m32r-use-generic-show_mem.patch --]
[-- Type: text/plain, Size: 1894 bytes --]

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

This also removes the following redundant information display:

	- 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().
