We found 2 bugs while we test and develop memory hotplug.
The hotplug code does not handle node_states[N_NORMAL_MEMORY] correctly, it may corrupt the memory.
And we ensure the SLUB do NOT respond when node_states[N_NORMAL_MEMORY] is not changed.
The patchset is based on mainline(3d0ceac129f3ea0b125289055a3aa7519d38df77)
