Subject: [patch 03/22 -v3] alpha: Use generic show_mem()
Date: Mon, 07 Apr 2008 16:40:11 +0200	[thread overview]
Message-ID: <20080407144239.565546337@skyscraper.fehenstaub.lan> (raw)
In-Reply-To: <20080407144008.124362640@skyscraper.fehenstaub.lan>

[-- Attachment #1: alpha-use-generic-show_mem.patch --]
[-- Type: text/plain, Size: 2922 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().
