The only difference was the calculation of memory -- it's more
complicated on i386 because of high memory support, so that was
outsourced to an inline function. However, because the highmem is in

  #ifdef CONFIG_HIGHMEM
  #endif

and CONFIG_HIGHMEM is off on x86-64, that doesn't matter. Do you see
another issue?

I tested it on both x86-64 and i386, with CONFIG_KEXEC on and off (so
that it compiles).
