From mboxrd@z Thu Jan 1 00:00:00 1970 Subject: [1/7] 050 bootmem use NODE_DATA In-Reply-To: <1098973549.shadowen.org Message-Id: From: Andy Whitcroft Date: Thu, 28 Oct 2004 15:25:55 +0100 Sender: owner-linux-mm@kvack.org Return-Path: To: haveblue@us.ibm.com, lhms-devel@lists.sourceforge.net Cc: linux-mm@kvack.org, apw@shadowen.org List-ID: Convert the default non-node based bootmem routines to use NODE_DATA(0). This is semantically and functionally identical in any non-node configuration as NODE_DATA(x) is defined as below. #define NODE_DATA(nid) (&contig_page_data) For the node cases (CONFIG_NUMA and CONFIG_DISCONTIG_MEM) we can use these non-node forms where all boot memory is defined on node 0.
