MIPS: Make local arrays with CL_SIZE static __initdata
Since commit 22242681cff52bfb7cba5d2a37b91802be7a4e4c ("MIPS: Extend
COMMAND_LINE_SIZE"), CL_SIZE is 4096 and local array variables with this
size will cause an build failure with default CONFIG_FRAME_WARN settings.
Although current users of such array variables are all early bootstrap
code and not likely to cause real stack overflow (thread_info corruption),
it is preferable to to declare these arrays static with __initdata.
