ARM: switch to use the generic show_mem() implementation
Switch ARM to use the generic show_mem() implementation, which displays the statistics from the mm zone rather than walking the page arrays. Acked-by: Mel Gorman <mgorman <mgorman@suse.de> Tested-by: Gregory Fong <gregory.0xf0@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
