Looks harmless enough on x86. The 32-bit code has some cruft in mem_init() after mem_init_print_info(), so this patch will change the location of the mem_init_print_info(), but I think it's actually for the better, since it will be pushed later in boot. As long as the x86 pieces stay the same: Acked-by: Dave Hansen <dave.hansen@linux.intel.com>
