I'm torn at the moment, as the net-next tree modules don't compile today.
Although 'make vmlinux' compiles this successfully, it is not tested.
Keep in mind that earlier variants were extensively tested.  But at least
this helps move the review comment process along....

Updated to patch cleanly with recent commits.

Changes from previous version:
  * swapped conditional tests, requested by Eric and Joe.
  * separate patch for constant cleanup, requested by Ilpo.
  * added hash generation of Responder Cookie with RCU locking.
  * shuffled a few bits to save another byte of tcp socket space.
