   1) RXRPC receive path fixes from David Howells.

   2) Re-export __skb_recv_udp(), from Jiri Kosina.

   3) Fix refcounting in u32 classificer, from Al Viro.

   4) Userspace netlink ABI fixes from Eugene Syromiatnikov.

   5) Don't double iounmap on rmmod in ena driver, from Arthur
      Kiyanovski.

   6) Fix devlink string attribute handling, we must pull a copy into a
      kernel buffer if the lifetime extends past the netlink request.
      From Moshe Shemesh.

   7) Fix hangs in RDS, from Ka-Cheong Poon.

   8) Fix recursive locking lockdep warnings in tipc, from Ying Xue.

   9) Clear RX irq correctly in socionext, from Ilias Apalodimas.

   10) bcm_sf2 fixes from Florian Fainelli."
