The boot cmdline is parsed in parse_early_param() and
parse_args(,unknown_bootoption).
And __setup() is used in obsolete_checksetup().
start_kernel()
-> parse_args()
-> unknown_bootoption()
-> obsolete_checksetup()
If __setup()'s callback (->setup_func()) returns 1 in
obsolete_checksetup(), obsolete_checksetup() thinks a parameter was
handled.
If ->setup_func() returns 0, obsolete_checksetup() tries other
->setup_func(). If all ->setup_func() that matched a parameter returns 0,
a parameter is seted to argv_init[].
Then, when runing /sbin/init or init=app, argv_init[] is passed to the app.
If the app doesn't ignore those arguments, it will warning and exit.
This patch fixes a wrong usage of it, however fixes obvious one only.

Initramfs initrd images do not need a ramdisk device, so remove this
restriction in Kconfig. BLK_DEV_RAM=n saves about 13k on i386. Also
without ramdisk device there's no need for "dry run", so initramfs unpacks
much faster.
People using cramfs, squashfs, or gzipped ext2/minix initrd images are
probably smart enough not to turn off ramdisk support by accident.

WARNING: drivers/block/floppy.o - Section mismatch: reference to \
.init.data: from .text between 'init_module' (at offset 0x6976) and \

The warning are caused by a reference to floppy_init() which is __init from
