Steffen Klassert says:

====================
1) Fix a possible race on ipcomp scratch buffers because
   of too early enabled siftirqs. From Michal Kubecek.

2) The current xfrm garbage collector threshold is too small
   for some workloads, resulting in bad performance on these
   workloads. Increase the threshold from 1024 to 32768.

3) Some codepaths might not have a dst_entry attached to the
   skb when calling xfrm_decode_session(). So add a check
   to prevent a null pointer dereference in this case.
