This patch is a result of trying to extend the kernel command-line size on x86 to more than 256 bytes. People requested to not allocate a larger buffers for small systems.
I don't know who should decide the tradeoff...
So what you basically say is that many modules need to be fixed... ./arch/avr32/boards/atstk1000/setup.c ./arch/frv/kernel/setup.c ./arch/i386/kernel/acpi/boot.c ./arch/i386/kernel/mpparse.c ./arch/i386/kernel/setup.c ./arch/ia64/kernel/setup.c <many more>
