We now provide a default (weak) implementation of memblock_nid_range() which uses the early_pfn_map[] if CONFIG_ARCH_POPULATES_NODE_MAP is set. Sparc still needs to use its own method due to the way the pages can be scattered between nodes. This implementation is inefficient due to our main algorithm and callback construct wanting to work on an ascending addresses bases while early_pfn_map[] would rather work with nid's (it's unsorted at that stage). But it should work and we can look into improving it subsequently, possibly using arch compile options to chose a different algorithm alltogether.
