What about the other archs ?

include/asm/setup.h:#define COMMAND_LINE_SIZE 256
include/asm/param.h:#define COMMAND_LINE_SIZE 256
include/asm-m68knommu/setup.h:#define COMMAND_LINE_SIZE 512
include/asm-powerpc/setup.h:#define COMMAND_LINE_SIZE 512

include/asm-parisc/setup.h:#define COMMAND_LINE_SIZE 1024
include/asm-x86_64/setup.h:#define COMMAND_LINE_SIZE 256
include/asm-xtensa/setup.h:#define COMMAND_LINE_SIZE 256

include/asm-frv/param.h:#define COMMAND_LINE_SIZE 512
include/asm-sparc64/setup.h:#define COMMAND_LINE_SIZE 256

Would it make sense to make it 1024 everywhere (and maybe move it out
of arch specific files and just set it in one central place) ?
