From mboxrd@z Thu Jan 1 00:00:00 1970 Subject: [1/6] generify early_pfn_to_nid Message-Id: From: Andy Whitcroft Date: Wed, 04 May 2005 21:21:56 +0100 Sender: owner-linux-mm@kvack.org Return-Path: To: akpm@osdl.org Cc: linux-mm@kvack.org, linux-kernel@vger.kernel.org, apw@shadowen.org, haveblue@us.ibm.com, kravetz@us.ibm.com List-ID: Provide a default implementation for early_pfn_to_nid returning node 0. Allow architectures to override this with their own implementation out of asm/mmzone.h.
