This is inconsistent with memblock_alloc() and what the function's sole user - sparc/mm/init_64 - expects, although it doesn't make any difference as sparc64 doesn't have highmem and ACCESSIBLE equals ANYWHERE. This patch makes memblock_alloc_try_nid() use ACCESSIBLE instead of ANYWHERE. This isn't complete as node affine allocation doesn't consider memblock.current_limit. It will be handled with future changes. This patch doesn't introduce any behavior difference.
