* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/penberg/slab-2.6: (27 commits)
  SLUB: Fix memory hotplug with !NUMA
  slub: Move functions to reduce #ifdefs
  slub: Enable sysfs support for !CONFIG_SLUB_DEBUG
  SLUB: Optimize slab_free() debug check
  slub: Move NUMA-related functions under CONFIG_NUMA
  slub: Add lock release annotation
  slub: Fix signedness warnings
  slub: extract common code to remove objects from partial list without locking
  SLUB: Pass active and inactive redzone flags instead of boolean to debug functions
  slub: reduce differences between SMP and NUMA
  Revert "Slub: UP bandaid"
  percpu: clear memory allocated with the km allocator
  percpu: use percpu allocator on UP too
  percpu: reduce PCPU_MIN_UNIT_SIZE to 32k
  vmalloc: pcpu_get/free_vm_areas() aren't needed on UP
  SLUB: Fix merged slab cache names
  Slub: UP bandaid
  slub: fix SLUB_RESILIENCY_TEST for dynamic kmalloc caches
  slub: Fix up missing kmalloc_cache -> kmem_cache_node case for memoryhotplug
  slub: Add dummy functions for the !SLUB_DEBUG case
