[David Miller <davem@davemloft.net>]

A decent batch of fixes here.  I'd say about half are for problems
that have existed for a while, and half are for new regressions added
in the 4.20 merge window.

1) Fix 10G SFP phy module detection in mvpp2, from Baruch Siach.

2) Revert bogus emac driver change, from Benjamin Herrenschmidt.

3) Handle BPF exported data structure with pointers when building
   32-bit userland, from Daniel Borkmann.

4) Memory leak fix in act_police, from Davide Caratti.

5) Check RX checksum offload in RX descriptors properly in aquantia
   driver, from Dmitry Bogdanov.

6) SKB unlink fix in various spots, from Edward Cree.

7) ndo_dflt_fdb_dump() only works with ethernet, enforce this, from
   Eric Dumazet.

8) Fix FID leak in mlxsw driver, from Ido Schimmel.

9) IOTLB locking fix in vhost, from Jean-Philippe Brucker.

10) Fix SKB truesize accounting in ipv4/ipv6/netfilter frag memory
    limits otherwise namespace exit can hang.  From Jiri Wiesner.

11) Address block parsing length fixes in x25 from Martin Schiller.

12) IRQ and ring accounting fixes in bnxt_en, from Michael Chan.

13) For tun interfaces, only iface delete works with rtnl ops, enforce
    this by disallowing add.  From Nicolas Dichtel.

14) Use after free in liquidio, from Pan Bian.

15) Fix SKB use after passing to netif_receive_skb(), from Prashant Bhole.

16) Static key accounting and other fixes in XPS from Sabrina Dubroca.

17) Partially initialized flow key passed to ip6_route_output(), from
    Shmulik Ladkani.

18) Fix RTNL deadlock during reset in ibmvnic driver, from Thomas
    Falcon.

19) Several small TCP fixes (off-by-one on window probe abort, NULL
    deref in tail loss probe, SNMP mis-estimations) from Yuchung Cheng.

Please pull, thanks a lot!
