    Subject[PATCH](memory hotplug) remove useless message at boot time from 2.6.18-rc3.
    This is to remove noisy useless message at boot time from 2.6.18-rc3.
    (-mm doesn't shows this message. I don't know why.)

    The message is a ton of
    "ACPI Exception (acpi_memory-0492): AE_ERROR, handle is no memory device"

    It is showed by acpi_memory_register_notify_handler() which
    is called by acpi_walk_namespace().

    acpi_walk_namespace() parses all of ACPI's namespace and
    executes acpi_memory_register_notify_handler(). So, it is called for
    all of the device which is defined in namespace. Even if
    the parsing device is not memory, it is normal route.
    So, this message is useless.

    I tested this patch for 2.6.18-rc3 on my box with hot-add emulation.

    Please apply.
