The idea was to allow putting something like "%s" in the built-in command line and expanding that with the provided command line. This allows you to append/prepend/ignore the provided command line as you desire. This is a fair bit more complicated than what the existing implementations of CONFIG_CMDLINE are doing and details like early_cmdline handling don't help matters. Haven't yet come up with an implementation I'm happy with.
Yes, and it's worth noting that with the edd stuff we actually parse the command line from real mode as well.
One way to do it would be to construct the command line in real mode code. It's not really all that hard, but wouldn't work for those that jump directly to the PM entrypoint.
