I looked for a way to do this. I think I figured out the parsing part.
But I can't see where to get the kernel command line from. The command
line that is parsed by modules in load_module comes from user mode, and
I think it's pre-processed by modprobe to strip the "<module>." prefix
and only include the module-specific options.

There is a global variable saved_command_line, which is what's used for
/proc/cmdline. But that variable is not exported to modules.
