The CONFIG_SMALLMEM would also require people to know what they are doing,
beyond what we expect the average person building a kernel to, which is
just what CONFIG_EXPERT means, and the same reason why we ended up renaming
CONFIG_EMBEDDED to CONFIG_EXPERT. People have a very different understanding
of what "embedded" actually means, and not all of those require small
memory footprint or even a custom kernel. Let's just stay with CONFIG_EXPERT.
