    ia64: remove custom __early_pfn_to_nid() · 03e92a5e
    Mike Rapoport authored
    The ia64 implementation of __early_pfn_to_nid() essentially relies on the
    same data as the generic implementation.
    
    The correspondence between memory ranges and nodes is set in memblock
    during early memory initialization in register_active_ranges() function.
    
    The initialization of sparsemem that requires early_pfn_to_nid() happens
    later and it can use the memblock information like the other architectures.
