Subject: pull request (net-next): ipsec-next 2016-09-08

1) Constify the xfrm_replay structures. From Julia Lawall

2) Protect xfrm state hash tables with rcu, lookups
   can be done now without acquiring xfrm_state_lock.
   From Florian Westphal.

3) Protect xfrm policy hash tables with rcu, lookups
   can be done now without acquiring xfrm_policy_lock.
   From Florian Westphal.

4) We don't need to have a garbage collector list per
   namespace anymore, so use a global one instead.
   From Florian Westphal.

Please pull or let me know if there are problems.

Thanks!

      xfrm: state: add sequence count to detect hash resizes
      xfrm: state: use rcu_deref and assign_pointer helpers

      xfrm: policy: use rcu versions for iteration and list add/del
      xfrm: policy: prepare policy_bydst hash for rcu lookups
      xfrm: policy: add sequence count to sync with hash resize
      xfrm: policy: use atomic_inc_not_zero in rcu section
      xfrm: policy: make xfrm_policy_lookup_bytype lockless

      xfrm: policy: don't acquire policy lock in xfrm_spd_getinfo
      xfrm: policy: convert policy_lock to spinlock
