mm: slab-allocate memory section nodemask for large systems
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.
