Sorry, I don't quite understand.

Is the issue that arcs_cmdline[] is declared as __initdata in
arch/mips/kernel/setup.c?

Note that it's ok to use arcs_cmdline on a non-ARCS machine.  ARC systems
were the first systems supported by Linux/MIPS, that's how the variable
got its name; the name was just never properly cleaned up but probably
should.
