If you want to place a variable in a specific section, it must be
explicitly initialised. Eg,
static char __initdata command_line[COMMAND_LINE_SIZE] = "";
However, there is a bigger question here: that is the tradeoff between
making this variable part of the on-disk kernel image, but throw away
the memory at runtime, or to leave it in the BSS where it will not be
part of the on-disk kernel image, but will not be thrown away at
runtime.
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>
