From a0140c1d85637ee5f4ea7c78f066e3611a6a79dc Mon Sep 17 00:00:00 2001 From: KAMEZAWA Hiroyuki Date: Mon, 27 Mar 2006 01:15:55 -0800 Subject: [PATCH] remove zone_mem_map This patch removes zone_mem_map. pfn_to_page uses pgdat, page_to_pfn uses zone. page_to_pfn can use pgdat instead of zone, which is only one user of zone_mem_map. By modifing it, we can remove zone_mem_map.
