Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/klassert/ipsec

Steffen Klassert says:

====================
1) Fix a sleep in atomic when pfkey_sadb2xfrm_user_sec_ctx()
   is called from pfkey_compile_policy().
   Fix from Nikolay Aleksandrov.

2) security_xfrm_policy_alloc() can be called in process and atomic
   context. Add an argument to let the callers choose the appropriate
   way. Fix from Nikolay Aleksandrov.
====================
