  slub: Deal with hyperthetical case of PAGE_SIZE > 2M
  slub: Remove node check in slab_free
  slub: avoid label inside conditional
  slub: Make CONFIG_DEBUG_PAGE_ALLOC work with new fastpath
  slub: Avoid warning for !CONFIG_SLUB_DEBUG
  slub: Remove CONFIG_CMPXCHG_LOCAL ifdeffery
  slub: Move debug handlign in __slab_free
  slub: Move node determination out of hotpath
  slub: Eliminate repeated use of c->page through a new page variable
  slub: get_map() function to establish map of free objects in a slab
  slub: Use NUMA_NO_NODE in get_partial
  slub: Fix a typo in config name
