Subject: [PATCH 11/20] mips: use generic show_mem()
Date: Fri, 27 Jun 2008 13:54:00 +0200	[thread overview]
Message-ID: <20080627120049.421752993@saeurebad.de> (raw)
In-Reply-To: 20080627115349.743368154@saeurebad.de

[-- Attachment #1: 0012-mips-use-generic-show_mem.patch --]
[-- Type: text/plain, Size: 2159 bytes --]

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

This also removes the following redundant information display:

	- pages in swapcache, printed by show_swap_cache_info()

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

And show_mem() does now actually print something on configurations
with multiple nodes.
