This is now the second Kconfig file we've got added into the tree.  As
with the PV-shim config, keeping it up to date is going to be a little
tricky.

I think we either need a script to keep all of the embedded configs up
to date, or switch to a model (similar to the travis randconfig target)
where it becomes a `make defaultconfig` with certain specific options
forced one way or another (similar to `make {tiny,kvm,xen}config` in
Linux).  The latter means that we only store the specific delta
applicable for purpose, and it will probably change less frequently.
