What do you think about following way to solve this:
1. To move this code: -
https://github.com/torvalds/linux/blob/master/arch/x86/kernel/setup.c#L971-L982
to the separate function, something like setup_cmdline().
2. Call setup_cmdline in head{32,64}.c and call
setup_early_printk(boot_command_line)
right after this.
After execution of the setup_cmdline, boot_command_line will be in
actual state. It will contain
command line which we passed to the kernel directly, or overwriten
with CONFIG_CMDLINE_OVERRIDE,
or appended with CONFIG_CMDLINE_OVERRIDE.
What do you think about this?
I already did it and tested on my local machine and it works, but
maybe I have missed something important.
