Put this in the "config X86_64" section and skip the "X86_64 &&"?

Can we omit the whole defer_meminit= thing and permanently enable the
feature? That's simpler, provides better test coverage and is, we
hope, faster.

And can this be used on non-NUMA? Presumably that won't speed things
up any if we're bandwidth limited but again it's simpler and provides
better coverage.
