Regardless, I don't think that the approach is correct. As per your description, some initialization functions erroneously call cpu_to_node() instead of early_cpu_to_node() which exists specifically for that case.
I checked the code again. The sparc, mips and s390 (which support the NUMA) do not support early_cpu_to_node(). So we cannot use early_cpu_to_node() for these functions. Thanks Huang Shijie
