====================
This pull request is intended for net-next and contains the following changes:

1) Remove a redundant check when initializing the xfrm replay functions,
   from Ulrich Weber.
2) Use a faster per-cpu helper when allocating ipcomt transforms,
   from Shan Wei.
3) Use a static gc threshold value for ipv6, simmilar to what we do
   for ipv4 now.
4) Remove a commented out function call.
