In short, early_initmem_init will parse numa info early and call init_mem_mapping to set page table for every nodes's mem. could be found at: git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git for-x86-mm and it is based on today's Linus tree that merges x86_urgent. Tested on x86 32bit non-numa/numa, 64bit non-numa/numa configurations.
