    in bnx2x, from Mauro S. M. Rodrigues.

 3) Don't double fetch 'len' from userspace in sock_getsockopt(), from
    JingYi Hou.

 4) Sign extension overflow in lio_core, from Colin Ian King.

 5) Various netem bug fixes wrt. corrupted packets from Jakub Kicinski.

 6) Fix epollout hang in hvsock, from Sunil Muthuswamy.

 7) Fix regression in default fib6_type, from David Ahern.

 8) Handle memory limits in tcp_fragment more appropriately, from Eric
    Dumazet.
