Node affine memblock allocation logic is currently implemented across memblock_alloc_nid() and memblock_alloc_nid_region(). This reorganizes it such that it resembles that of non-NUMA allocation API. Area finding is collected and moved into new exported function memblock_find_in_range_node() which is symmetrical to non-NUMA counterpart - it handles @start/@end and understands ANYWHERE and ACCESSIBLE. memblock_alloc_nid() now simply calls memblock_find_in_range_node() and reserves the returned area. This makes memblock_alloc[_try]_nid() observe ACCESSIBLE limit on node affine allocations too (again, this doesn't make any difference for the current sole user - sparc64).
