I didn't see anything wrong with the patches, and made sure that there
are no tristate symbols controlling the subdirectory for anything that
requires a built-in driver (which would cause a link failure).

I'm not sure about drivers/lguest, which has some special magic
in its Makefile, it's possible that this now fails with CONFIG_LGUEST=m.
