Merge branch 'work.sock_recvmsg' of git://git./linux/kernel/git/viro/vfs

Pull kern_recvmsg reduction from Al Viro:
 "kernel_recvmsg() is a set_fs()-using wrapper for sock_recvmsg(). In
  all but one case that is not needed - use of ITER_KVEC for ->msg_iter
  takes care of the data and does not care about set_fs(). The only
  exception is svc_udp_recvfrom() where we want cmsg to be store into
  kernel object; everything else can just use sock_recvmsg() and be done
  with that.

  A followup converting svc_udp_recvfrom() away from set_fs() (and
  killing kernel_recvmsg() off) is *NOT* in here - I'd like to hear what
  netdev folks think of the approach proposed in that followup)"
