The variable "cmd_line" is being used in generic code of device tree,
most of platforms (ARM, POWERPC
, etc) have its definition, but it isn't present in MIPS. Actually there
is a variable "arcs_cmdline" to be used as the same purpose in MIPS,
that is the reason "arcs_cmdline" is given a new name.


Thanks
