Sorry. I realize that I forgot to remove old sysfs structure of node for ia64 in yesterday's patch. :-( Please apply this too. ------------- Creating sysfs file for node is consolidated as generic code by creating registrer_one_node() and node_devices[]. But, ia64's boot time code remains old sysfs_nodes structure as an arch dependent code. This is to remove it. This patch is for 2.6.17-rc4-mm1 with + register-sysfs-file-for-hotpluged-new-node.patch I tested this on Tiger4 box with my multi nodes emulation.
