parse_early_param() is right AFTER this in the x86 setup_arch()
function (in arch/x86/kernel/setup.c).  All the other command-line
handling I could find is after this in init/main.c:start_kernel().

There is some stuff earlier in the setup_arch() routine about
boot_params, but that looks like it's related to the old(?)
binary data points you can jam into the kernel image.  (That is,
it doesn't look like it's related to the command line handling).
