Hello.

I'll post newest patches for memory hotadd.
In this this patch, pgdat is allocated when new node is comming.
To initialize pgdat and zones, a set of patches are necessary.
  - to allcate and initialize pgdat, zone, zonelist.
  - to initialize node_data[] array (ia64)
  - to register sysfs file for new node.
  - to call memory_hotplug code from acpi container driver.

Note:
 - kmalloc is used for pgdat allocation in this version.
   So, even if pgdat is allocated, it will be allocated on the other node.
   This is only to simplify patches a bit. :-P
 - register sysfs file for new node is just for ia64.
   I hacked quickly for x86_64, but x86_64 doesn't use sysfs file
   for node. So, I gave up at least this week.....


This patches are for 2.6.16-rc2-mm1.

Please comment.

Thanks.
