Since CONFIG_RAMFS is currently hard-selected to "y", and since
Documentation/filesystems/ramfs-rootfs-initramfs.txt reads as follows:
"The amount of code required to implement ramfs is tiny, because all
the work is done by the existing Linux caching infrastructure.
Basically, you're mounting the disk cache as a filesystem. Because of
this, ramfs is not an optional component removable via menuconfig,
since there would be negligible space savings."
it seems pointless to leave this as a Kconfig entry.

this also allows almost 300 "CONFIG_RAMFS=y" lines to be dropped
from various defconfig files. and that horribly misleading Kconfig
help text disappears as well. :-)
compile tested under i386.

- Ramfs is a file system which keeps all files in RAM. It allows
- read and write access.
-
- It is more of an programming example than a useable file system. If
- you need a file system which lives in RAM with limit checking use
- tmpfs.
-
- To compile this as a module, choose M here: the module will be called
- ramfs.
