Hi.

These are parts of patches for new nodes addition v4.
I picked them up because v4 might be a bit too many patches.
These patches can be used even when a new zone becomes available.
When empty zone becomes not empty, wait_table must be initialized,
and zonelists must be updated.
So, They are a good group for once post.

ex) x86-64 is good example of new zone addition.
- System boot up with memory under 4G address.
All of memory will be ZONE_DMA32.
- Then hot-add over 4G memory. It becomes ZONE_NORMAL. But,
wait table of zone normal is not initialized at this time.

This patch is for 2.6.17-rc1-mm1.

Please apply.

----------------------------
Change log from v4 of hot-add.
- update for 2.6.17-rc1-mm1.
- change allocation for wait_table from kmalloc() to vmalloc().
vmalloc() is enough for it.

V4 of post is here.
