====================
Netfilter fixes for net

The following patchset contains four Netfilter fixes for net, they are:

1) Fix Kconfig dependencies of new nf_dup_ipv4 and nf_dup_ipv6.

2) Remove bogus test nh_scope in IPv4 rpfilter match that is breaking
   --accept-local, from Xin Long.

3) Wait for RCU grace period after dropping the pending packets in the
   nfqueue, from Florian Westphal.

4) Fix sleeping allocation while holding spin_lock_bh, from Nikolay Borisov.
