    ====================
    pull request (net-next): ipsec-next 2013-12-19
    
    1) Use the user supplied policy index instead of a generated one
       if present. From Fan Du.
    
    2) Make xfrm migration namespace aware. From Fan Du.
    
    3) Make the xfrm state and policy locks namespace aware. From Fan Du.
    
    4) Remove ancient sleeping when the SA is in acquire state,
       we now queue packets to the policy instead. This replaces the
       sleeping code.
    
    5) Remove FLOWI_FLAG_CAN_SLEEP. This was used to notify xfrm about the
       posibility to sleep. The sleeping code is gone, so remove it.
    
    6) Check user specified spi for IPComp. Thr spi for IPcomp is only
       16 bit wide, so check for a valid value. From Fan Du.
    
    7) Export verify_userspi_info to check for valid user supplied spi ranges
       with pfkey and netlink. From Fan Du.
    
    8) RFC3173 states that if the total size of a compressed payload and the IPComp
       header is not smaller than the size of the original payload, the IP datagram
       must be sent in the original non-compressed form. These packets are dropped
       by the inbound policy check because they are not transformed. Document the need
       to set 'level use' for IPcomp to receive such packets anyway. From Fan Du.
    
    Please pull or let me know if there are problems.
