(allocate pgdat for ia64) Cc: linux-ia64@vger.kernel.org, Linux Kernel ML , linux-mm , Andrew Morton X-Mailer-Plugin: BkASPil for Becky!2 Ver.2.063 Message-Id: <20060308213020.0032.Y-GOTO@jp.fujitsu.com> MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit X-Mailer: Becky! ver. 2.24.02 [ja] Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1457 Lines: 47 This is a patch to allocate pgdat and per node data area for ia64. The size for them can be calculated by compute_pernodesize().
