* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86-bigbox-bootmem-v3:
  x86_64/mm: check and print vmemmap allocation continuous
  x86_64: fix setup_node_bootmem to support big mem excluding with memmap
  x86_64: make reserve_bootmem_generic() use new reserve_bootmem()
  mm: allow reserve_bootmem() cross nodes
  mm: offset align in alloc_bootmem()
  mm: fix alloc_bootmem_core to use fast searching for all nodes
  mm: make mem_map allocation continuous
