As of commit 8f32b90981
("net: ethernet: ti: davinci_cpdma: add set rate for a channel") the
ARM allmodconfig builds would fail modpost with:
ERROR: "cpdma_chan_set_weight" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!

ERROR: "cpdma_chan_set_rate" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
Since these weren't declared as static, it is assumed they were
meant to be shared outside the file, and that modular build testing
was simply overlooked.

As David Miller pointed out for for the previous patch, the whitespace
in some functions looks rather odd. This was caused by commit 6329da5f25
("obsolete config in kernel source: USE_INTERNAL_TIMER"), which removed
some conditions but did not reindent the code.
This fixes the indentation in the file and removes extraneous whitespace
at the end of the lines and before tabs.
There are many other minor coding style problems in the driver, but I'm

Couple conflicts resolved here:
1) In the MACB driver, a bug fix to properly initialize the
RX tail pointer properly overlapped with some changes
to support variable sized rings.
2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
overlapping with a reorganization of the driver to support
ACPI, OF, as well as PCI variants of the chip.
3) In 'net' we had several probe error path bug fixes to the
stmmac driver, meanwhile a lot of this code was cleaned up
and reorganized in 'net-next'.
4) The cls_flower classifier obtained a helper function in
'net-next' called __fl_delete() and this overlapped with
Daniel Borkamann's bug fix to use RCU for object destruction
in 'net'. It also overlapped with Jiri's change to guard
the rhashtable_remove_fast() call with a check against
tc_skip_sw().
5) In mlx4, a revert bug fix in 'net' overlapped with some
unrelated changes in 'net-next'.
6) In geneve, a stale header pointer after pskb_expand_head()
bug fix in 'net' overlapped with a large reorganization of
the same code in 'net-next'. Since the 'net-next' code no
longer had the bug in question, there was nothing to do
other than to simply take the 'net-next' hunks.

A previous workaround added to ensure receipt of all broadcast frames
incorrectly set the broadcast promiscuous mode unconditionally
regardless of active VLAN status.
Replace this partial workaround with a complete solution that sets the
broadcast promiscuous filters in i40e_sync_vsi_filters. This new method
sets the promiscuous mode based on when broadcast filters are added or
removed.
I40E_VLAN_ANY will request a broadcast filter for all VLANs, (as we're
in untagged mode) while a broadcast filter on a specific VLAN will only
request broadcast for that VLAN.
Thus, we restore addition of broadcast filter to the array, but we add
special handling for these such that they enable the broadcast
promiscuous mode instead of being sent as regular filters.
The end result is that we will correctly receive all broadcast packets
(even those with a *source* address equal to the broadcast address) but
will not receive packets for which we don't have an active VLAN filter.

This patch fixes the problem where the ethtool Supported link
modes list backplane interfaces on X722 devices for 10GbE with
SFP+ and Cortina retimer. This patch fixes the problem by setting
and using a flag for this particular device since the backplane
interface is only between the internal PHY and the retimer and it
should not be seen by the user as they cannot use it.
Without this patch, the user wrongly thinks that backplane interfaces
are supported on their device when they actually are not.

The PHY type value for unrecognized PHYs and cables was changed
based on firmware version number. Newer hardware use lower firmware
version numbers and this was causing some PHYs to be identified

Without this patch, newer card will incorrectly identify unknown

This change adds hardware type to the check for firmware version

this is minute long snapshot which didn't take a single page from the
LRU. It is not entirely clear why only 1303 pages have been scanned
during that time (maybe there was a heavy IRQ activity interfering).
In any case it looks like we can really hit long periods without
scheduling on non preemptive kernels so an explicit cond_resched() in
shrink_node_memcg which is independent on the reclaim operation is due.

When building a specific target such as bzImage, modules aren't normally
built. However if CONFIG_TRIM_UNUSED_KSYMS is enabled, no built modules
means none of the exported symbols are used and therefore they will all
be trimmed away from the final kernel. A subsequent "make modules" will
fail because modpost cannot find the needed symbols for those modules in
the kernel binary.
Let's make sure modules are also built whenever CONFIG_TRIM_UNUSED_KSYMS
is enabled and that the kernel binary is properly rebuilt accordingly.

This should be the last set of bugfixes for arm-soc in v4.9.
None of these are critical regressions, but it would be nice
to still get them merged.
- On the Juno platform, the idle latency was described wrong,
leading to suboptimal cpuidle tuning.
- Also on the same platform, PCI I/O space was set up incorrectly
and could not work.
- On the sti platform, a syntactically incorrect DT entry caused
warnings.
- The newly added 'gr8' platform has somewhat confusing file
names, which we rename for consistency.

Pull ARM SoC fixes from Arnd Bergmann:
"This should be the last set of bugfixes for arm-soc in v4.9. None of
these are critical regressions, but it would be nice to still get them
merged.
- On the Juno platform, the idle latency was described wrong, leading
to suboptimal cpuidle tuning.
- Also on the same platform, PCI I/O space was set up incorrectly and
could not work.
- On the sti platform, a syntactically incorrect DT entry caused
warnings.
- The newly added 'gr8' platform has somewhat confusing file names,
which we rename for consistency"

Pull networking fixes from David Miller:
1) Lots more phydev and probe error path leaks in various drivers by
Johan Hovold.
2) Fix race in packet_set_ring(), from Philip Pettersson.
3) Use after free in dccp_invalid_packet(), from Eric Dumazet.
4) Signnedness overflow in SO_{SND,RCV}BUFFORCE, also from Eric
Dumazet.
5) When tunneling between ipv4 and ipv6 we can be left with the wrong
skb->protocol value as we enter the IPSEC engine and this causes all
kinds of problems. Set it before the output path does any
dst_output() calls, from Eli Cooper.
6) bcmgenet uses wrong device struct pointer in DMA API calls, fix from
Florian Fainelli.
7) Various netfilter nat bug fixes from FLorian Westphal.
8) Fix memory leak in ipvlan_link_new(), from Gao Feng.
9) Locking fixes, particularly wrt. socket lookups, in l2tp from
Guillaume Nault.
10) Avoid invoking rhash teardowns in atomic context by moving netlink
cb->done() dump completion from a worker thread. Fix from Herbert
Xu.
11) Buffer refcount problems in tun and macvtap on errors, from Jason
Wang.
12) We don't set Kconfig symbol DEFAULT_TCP_CONG properly when the user
selects BBR. Fix from Julian Wollrath.
13) Fix deadlock in transmit path on altera TSE driver, from Lino
Sanfilippo.
14) Fix unbalanced reference counting in dsa_switch_tree, from Nikita
Yushchenko.
15) tc_tunnel_key needs to be properly exported to userspace via uapi,
fix from Roi Dayan.
16) rds_tcp_init_net() doesn't unregister notifier in error path, fix
from Sowmini Varadhan.
17) Stale packet header pointer access after pskb_expand_head() in
genenve driver, fix from Sabrina Dubroca.

CAP_NET_ADMIN users should not be allowed to set negative
sk_sndbuf or sk_rcvbuf values, as it can lead to various memory
corruptions, crashes, OOM...
Note that before commit 8298193012 ("net: cleanups in
sock_setsockopt()"), the bug was even more serious, since SO_SNDBUF
and SO_RCVBUF were vulnerable.
This needs to be backported to all known linux kernels.
Again, many thanks to syzkaller team for discovering this gem.

geneve{,6}_build_skb can end up doing a pskb_expand_head(), which
makes the ip_hdr(skb) reference we stashed earlier stale. Since it's
only needed as an argument to ip_tunnel_ecn_encap(), move this
directly in the function call.

Qian Zhang (张谦) reported a potential socket buffer overflow in
tipc_msg_build() which is also known as CVE-2016-8632: due to
insufficient checks, a buffer overflow can occur if MTU is too short for
even tipc headers. As anyone can set device MTU in a user/net namespace,
this issue can be abused by a regular user.
As agreed in the discussion on Ben Hutchings' original patch, we should
check the MTU at the moment a bearer is attached rather than for each
processed packet. We also need to repeat the check when bearer MTU is
adjusted to new device MTU. UDP case also needs a check to avoid
overflow when calculating bearer MTU.

We want to set the other "err" variable here so that we can return it
later. My version of GCC misses this issue but I caught it with a
static checker.
