From 10ad400b49aca15ecf83b0fde7e35e4064b15c85 Mon Sep 17 00:00:00 2001 From: Yasunori Goto Date: Tue, 27 Jun 2006 02:53:33 -0700 Subject: [PATCH] pgdat allocation for new node add (refresh node_data[]) Refresh NODE_DATA() for generic archs. In this case, NODE_DATA(nid) == node_data[nid]. node_data[] is array of address of pgdat. So, refresh is quite simple.
