-0700 committer Linus Torvalds 1151454756 -0700 [PATCH] pgdat allocation and update for ia64 of memory hotplug: hold pgdat address at system running This is a preparatory patch to make common code for updating of NODE_DATA() of ia64 between boottime and hotplug. Current code remembers pgdat address in mem_data which is used at just boot time. But its information can be used at hotplug time by moving to global value. The next patch uses this array.
