This feature is very important for node hotplug. So we will add a new nodemask for all memory. N_MEMORY contains movable memory but N_HIGH_MEMORY doesn't contain it. We don't remove N_HIGH_MEMORY because it can be used to search which nodes contains memory that the kernel can use. The movable node will implemtent in part4. So N_MEMORY is equal to N_HIGH_MEMORY now.
