 *	arch-specific/loader-specific ones.
 * o	Then, arch_process_options() uses this complete list to scan for its
 *	options, ignoring general/loader-specific ones.
 * o	Then, the file_type[n].load re-scans for options, using
 *	KEXEC_ARCH_OPTIONS plus its loader-specific options subset.
 *	Any unrecognised options cause an error here.

 * This is done so that main()'s/arch_process_options()'s getopt_long() calls
 * don't choose a kernel filename from random arguments to options they don't
 * recognise -- as they now recognise (if not act upon) all possible options.
