bc02af93dd [PATCH] pgdat allocation for new node add (specify node id)
Change the name of old add_memory() to arch_add_memory.  And use node id to
get pgdat for the node at NODE_DATA().

Note: Powerpc's old add_memory() is defined as __devinit. However,
      add_memory() is usually called only after bootup.
      I suppose it may be redundant. But, I'm not well known about powerpc.
      So, I keep it. (But, __meminit is better at least.)

dd56a8e36f [PATCH] Catch notification of memory add event of ACPI via container driver. (avoid redundant call add_memory)
When acpi_memory_device_init() is called at boottime to register struct
memory acpi_memory_device, acpi_bus_add() are called via
acpi_driver_attach().

But it also calls ops->start() function.  It is called even if the memory
blocks are initialized at early boottime.  In this case add_memory() return
-EEXIST, and the memory blocks becomes INVALID state even if it is normal.

This is patch to avoid calling add_memory() for already available memory.

1f425994f9 [PATCH] Catch notification of memory add event of ACPI via container driver. (register start func for memory device)
This is a patch to call add_memroy() when notify reaches for new node's add
event.

When new node is added, notify of ACPI reaches container device which means
the node.

Container device driver calls acpi_bus_scan() to find and add belonging
devices (which means cpu, memory and so on).  Its function calls add and
start function of belonging devices's driver.

Howevever, current memory hotplug driver just register add function to
create sysfs file for its memory.  But, acpi_memory_enable_device() is not
called because it is considered just the case that notify reaches memory
device directly.  So, if notify reaches container device nothing can call
add_memory().

This is a patch to create start function which calls add_memory().
add_memory() can be called by this when notify reaches container device.

9ac023989e [PATCH] acpi memory hotplug cannot manage _CRS with plural resoureces
Current acpi memory hotplug just looks into the first entry of resources in
_CRS.  But, _CRS can contain plural resources.  So, if _CRS contains plural
resoureces, acpi memory hot add cannot add all memory.

With this patch, acpi memory hotplug can deal with Memory Device, whose
_CRS contains plural resources.

Tested on ia64 memory hotplug test envrionment (not emulation, uses alpha
version firmware which supports dynamic reconfiguration of NUMA.)

Note: Microsoft's Windows Server 2003 requires big (>4G)resoureces to be
      divided into small (<4G) resources. looks crazy, but not invalid.
      (See http://www.microsoft.com/whdc/system/pnppwr/hotadd/hotaddmem.mspx)
      For this reason, a firmware vendor who supports Windows writes plural
      resources in a _CRS even if they are contiguous.

266bee8869 [PATCH] fix static linking of NFS
Builds on ARM report link problems with common configurations like
statically linked NFS (for nfsroot).  The symptom is that __init
section code references __exit section code; that won't work since
the exit sections are discarded (since they can never be called).

The best fix for these particular cases would be an "__init_or_exit"
section annotation.

This reverts commit e5c44fd88c.

Thanks to Daniel Ritz and Michal Piotrowski for noticing the problem.

Daniel says:

  "[The] reason is a recent change that made modules always shows as
   module.mod.  it breaks modprobe and probably many scripts..besides
   lsmod looking horrible

   stuff like this in modprobe.conf:
        install pcmcia_core /sbin/modprobe --ignore-install pcmcia_core; /sbin/modprobe pcmcia
   makes modprobe fork/exec endlessly calling itself...until oom
   interrupts it"
