   2) Fix 64-bit division in iwlwifi, from Arnd Bergmann.

   3) Fix documentation for some eBPF helpers, from Quentin Monnet.

   4) Some UAPI bpf header sync with tools, also from Quentin Monnet.

   5) Set descriptor ownership bit at the right time for jumbo frames in
      stmmac driver, from Aaro Koskinen.

   6) Set IFF_UP properly in tun driver, from Eric Dumazet.

   7) Fix load/store doubleword instruction generation in powerpc eBPF
      JIT, from Naveen N. Rao.

   8) nla_nest_start() return value checks all over, from Kangjie Lu.

   9) Fix asoc_id handling in SCTP after the SCTP_*_ASSOC changes this
      merge window. From Marcelo Ricardo Leitner and Xin Long.

  10) Fix memory corruption with large MTUs in stmmac, from Aaro
      Koskinen.

  11) Do not use ipv4 header for ipv6 flows in TCP and DCCP, from Eric
      Dumazet.

  12) Fix topology subscription cancellation in tipc, from Erik Hugne.

  13) Memory leak in genetlink error path, from Yue Haibing.

  14) Valid control actions properly in packet scheduler, from Davide
      Caratti.

  15) Even if we get EEXIST, we still need to rehash if a shrink was
      delayed. From Herbert Xu.

  16) Fix interrupt mask handling in interrupt handler of r8169, from
      Heiner Kallweit.

  17) Fix leak in ehea driver, from Wen Yang"

* Consider the following where "sk" is a reference counted
* pointer returned from "sk = bpf_sk_lookup_tcp();":
*
* 1: sk = bpf_sk_lookup_tcp();
* 2: if (!sk) { return 0; }

* 8: snd_cwnd = tp->snd_cwnd; // verifier will complain
*
* After bpf_sk_release(sk) at line 7, both "fullsock" ptr and
* "tp" ptr should be invalidated also. In order to do that,
* the reg holding "fullsock" and "sk" need to remember
* the original refcounted ptr id (i.e. sk_reg->id) in ref_obj_id
* such that the verifier can reset all regs which have
* ref_obj_id matching the sk_reg->id.
*
* sk_reg->ref_obj_id is set to sk_reg->id at line 1.
* sk_reg->id will stay as NULL-marking purpose only.
* After NULL-marking is done, sk_reg->id can be reset to 0.
*
* After "fullsock = bpf_sk_fullsock(sk);" at line 3,
* fullsock_reg->ref_obj_id is set to sk_reg->ref_obj_id.
*
* After "tp = bpf_tcp_sock(fullsock);" at line 5,
* tp_reg->ref_obj_id is set to fullsock_reg->ref_obj_id
* which is the same as sk_reg->ref_obj_id.
*
* From the verifier perspective, if sk, fullsock and tp
* are not NULL, they are the same ptr with different
* reg->type. In particular, bpf_sk_release(tp) is also
* allowed and has the same effect as bpf_sk_release(sk).
