From dd0932d9d4301bd58a4d5a634a3a8298c4fc5e24 Mon Sep 17 00:00:00 2001 From: Yasunori Goto Date: Tue, 27 Jun 2006 02:53:40 -0700 Subject: [PATCH] pgdat allocation and update for ia64 of memory hotplug: allocate pgdat and per node data This is a patch to allocate pgdat and per node data area for ia64. The size for them can be calculated by compute_pernodesize().
