Sorry for the churn here, but I think these need to be reverted.

We've discoverd some more complexities/issues when socinfo is modular,
and I think the socinfo core code needs some work before this can
actually work reliably for all socinfo users.

Basically, I think we need to finish converting all the socinfo users to
modules before we can be sure of all the corner cases when socinfo
itself is a module.

Sorry about this churn, but I think it's better to be a bit conservative
here and revert before this lands in mainline.

Thanks,

Kevin
