Now that NUMA init path is unified, NUMA emulation can be enabled on 32bit. Make numa_emluation.c safe on 32bit by doing the followings. * Define MAX_DMA32_PFN on 32bit too. * Include bootmem.h for max_pfn declaration. * Use u64 explicitly and always use PFN_PHYS() when converting page number to address. * Avoid __udivdi3() generation on 32bit by doing number of pages calculation instead in split_nodes_interleave(). And drop X86_64 dependency from Kconfig.
