Nodemasks should not be allocated on the stack for large systems (when it is larger than 256 bytes) since there is a threat of overflow. This patch causes the unregister_mem_sect_under_nodes() nodemask to be allocated on the stack for smaller systems and be allocated by slab for larger systems. GFP_KERNEL is used since remove_memory_block() can block.
