Matt would be dealing with that aspect in his unification: SHMEM
depends on MMU, so !MMU gives you TINY_SHMEM - I'm sure he wouldn't
have any of the SWAP stuff in the TINY_SHMEM part of his unification.
But there's still value in adding CONFIG_SWAPs too (if the #ifdefs
were tolerable, by no means clear).
