  [SPARC64]: NUMA device infrastructure.
  [SPARC64]: Kill pci_iommu_table_init() declaration.
  [SPARC64]: Once we have the boot cmdline, call parse_early_param()
  [SPARC64]: Remove unused asm-sparc64/numnodes.h
  [SPARC64]: Decrease SECTION_SIZE_BITS to 30.
  [SPARC64]: Initialize MDESC earlier and use lmb_alloc()
  [SPARC64]: Use lmb_alloc() for PROM device tree.
  [SPARC64]: Call real_setup_per_cpu_areas() earlier and use lmb_alloc().
  [SPARC64]: Fully use LMB information in bootmem_init().
