Subject: [patch 04/22 -v2] avr32: Use generic show_mem()
Date: Fri, 04 Apr 2008 13:51:41 +0200	[thread overview]
Message-ID: <20080404115231.162496419@skyscraper.fehenstaub.lan> (raw)
In-Reply-To: <20080404115137.397502419@skyscraper.fehenstaub.lan>

[-- Attachment #1: avr32-use-generic-show_mem.patch --]
[-- Type: text/plain, Size: 2188 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 slabs, 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().
