From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Wed, 16 Nov 2005 22:59:53 +0000 Subject: [PATCH 0/3] SPARSEMEM: pfn_to_nid implementation Message-ID: References: <20051115221003.GA2160@w-mikek2.ibm.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline From: Andy Whitcroft Sender: owner-linux-mm@kvack.org Return-Path: To: Mike Kravetz Cc: Andy Whitcroft , Anton Blanchard , linux-kernel@vger.kernel.org, linux-mm@kvack.org List-ID: I have reviewed the uses of pfn_to_nid() in 2.6.14-mm2. The only user of the non-init pfn_to_nid is the one in check_pte_range(). So we simply need to profide a non-early pfn_to_nid() implementation for SPARSEMEM. Whilst reviewing these interfaces I found two alternative dependant interfaces which are not used. Following this message are three patches: kvaddr_to_nid-not-used-in-common-code: removes the unused interface kvaddr_to_nid(). pfn_to_pgdat-not-used-in-common-code: removes the unused interface pfn_to_pgdat(). sparse-provide-pfn_to_nid: provides pfn_to_nid() for SPARSEMEM. Note that this implmentation assumes the pfn has been validated prior to use. The only intree user of this call does this. We perhaps need to make this part of the signature for this function. Mike, how does this look to you? -apw -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
