Pull networking updates from David Miller:
"This is a re-do of the net-next pull request for the current merge
window. The only difference from the one I made the other day is that
this has Eliezer's interface renames and the timeout handling changes
made based upon your feedback, as well as a few bug fixes that have
trickeled in.
Highlights:
1) Low latency device polling, eliminating the cost of interrupt
handling and context switches. Allows direct polling of a network
device from socket operations, such as recvmsg() and poll().
Currently ixgbe, mlx4, and bnx2x support this feature.
Full high level description, performance numbers, and design in
commit 0a4db187a999 ("Merge branch 'll_poll'")
From Eliezer Tamir.
2) With the routing cache removed, ip_check_mc_rcu() gets exercised
more than ever before in the case where we have lots of multicast
addresses. Use a hash table instead of a simple linked list, from
Eric Dumazet.
3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from
Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski,
Marek Puzyniak, Michal Kazior, and Sujith Manoharan.
4) Support reporting the TUN device persist flag to userspace, from
Pavel Emelyanov.
5) Allow controlling network device VF link state using netlink, from
Rony Efraim.
6) Support GRE tunneling in openvswitch, from Pravin B Shelar.
7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from
Daniel Borkmann and Eric Dumazet.
8) Allow controlling of TCP quickack behavior on a per-route basis,
from Cong Wang.
9) Several bug fixes and improvements to vxlan from Stephen
Hemminger, Pravin B Shelar, and Mike Rapoport. In particular,
support receiving on multiple UDP ports.
10) Major cleanups, particular in the area of debugging and cookie
lifetime handline, to the SCTP protocol code. From Daniel
Borkmann.
11) Allow packets to cross network namespaces when traversing tunnel
devices. From Nicolas Dichtel.
12) Allow monitoring netlink traffic via AF_PACKET sockets, in a
manner akin to how we monitor real network traffic via ptype_all.
From Daniel Borkmann.
13) Several bug fixes and improvements for the new alx device driver,
from Johannes Berg.
14) Fix scalability issues in the netem packet scheduler's time queue,
by using an rbtree. From Eric Dumazet.
15) Several bug fixes in TCP loss recovery handling, from Yuchung
Cheng.
16) Add support for GSO segmentation of MPLS packets, from Simon
Horman.
17) Make network notifiers have a real data type for the opaque
pointer that's passed into them. Use this to properly handle
network device flag changes in arp_netdev_event(). From Jiri
Pirko and Timo Teräs.
18) Convert several drivers over to module_pci_driver(), from Peter
Huewe.
19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a
O(1) calculation instead. From Eric Dumazet.
20) Support setting of explicit tunnel peer addresses in ipv6, just
like ipv4. From Nicolas Dichtel.
21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet.
22) Prevent a single high rate flow from overruning an individual cpu
during RX packet processing via selective flow shedding. From
Willem de Bruijn.
23) Don't use spinlocks in TCP md5 signing fast paths, from Eric
Dumazet.
24) Don't just drop GSO packets which are above the TBF scheduler's
burst limit, chop them up so they are in-bounds instead. Also
from Eric Dumazet.
25) VLAN offloads are missed when configured on top of a bridge, fix
from Vlad Yasevich.
26) Support IPV6 in ping sockets. From Lorenzo Colitti.
27) Receive flow steering targets should be updated at poll() time
too, from David Majnemer.
28) Fix several corner case regressions in PMTU/redirect handling due
to the routing cache removal, from Timo Teräs.
29) We have to be mindful of ipv4 mapped ipv6 sockets in
upd_v6_push_pending_frames(). From Hannes Frederic Sowa.
30) Fix L2TP sequence number handling bugs, from James Chapman."

The port number is only local to the ethernet block, not global, so

kirkwood with both using port 0.

Commit 2768935a4660 ('sfc: reuse pages to avoid DMA mapping/unmapping
costs') did not fully take account of DMA scattering which was
introduced immediately before. If a received packet is invalid and
must be discarded, we only drop a reference to the first buffer's
page, but we need to drop a reference for each buffer the packet
used.
I think this bug was missed partly because efx_recycle_rx_buffers()
was not renamed and so no longer does what its name says. It does not
change the state of buffers, but only prepares the underlying pages
for recycling. Rename it accordingly.

Pull device tree updates from Grant Likely:
"This branch contains the following changes:
- Removal of CONFIG_OF_DEVICE, it is always enabled by CONFIG_OF
- Remove #ifdef from linux/of_platform.h to increase compiler syntax
coverage
- Bug fix for address decoding on Bimini and js2x powerpc platforms.
- miscellaneous binding changes
One note on the above. The binding changes going in from all kinds of
different trees has gotten rather out of hand. I picked up some
during this cycle, but even going though my tree isn't a great fit.
Ian Campbell has prototyped splitting the bindings and .dtb files into
a separate repository. The plan is to migrate to using that sometime
in the next few kernel releases which should get rid of a lot of the
churn on binding docs and .dts files"

This patch adds phy reset callback support for stmmac driver via device
trees. It adds three new properties to gmac device tree bindings to
define the reset signal via gpio.
With this patch users can conveniently pass reset gpio number with pre,
pulse and post delay in micro secs via DTs.

Pull pin control changes from Linus Walleij:
- A large slew of improvements of the Genric pin configuration support,
and deployment in four different platforms: Rockchip, Super-H PFC,
ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing
and debugfs support into shape.
- We also have device tree support with generic naming conventions for
the generic pin configuration.
- Delete the unused and confusing direct pinconf API. Now state
transitions is *the* way to control pins and multiplexing.
- New drivers for Rockchip, TZ1090, and TZ1090 PDC.
- Two pin control states related to power management are now handled in
the device core: "sleep" and "idle", removing a lot of boilerplate
code in drivers. We do not yet know if this is the final word for
pin PM, but it already make things a lot easier to handle.
- Handle sparse GPIO ranges passing a list of disparate pins, and
utilize these in the new BayTrail (x86 Atom SoC) driver.
- Make the sunxi (AllWinner) driver handle external interrupts.
- Make it possible for pinctrl-single to handle the case where several
pins are managed by a single register, and augment it to handle sleep
modes.
- Cleanups and improvements for the abx500 drivers.
- Move Sirf pin control drivers to their own directory, support
save/restore of context and add support for the SiRFatlas6 SoC.
- PMU muxing for the Dove pinctrl driver.
- Finalization and support for VF610 in the i.MX6 pinctrl driver.
- Smoothen out various Exynos rough edges.
- Generic cleanups of various kinds.

There is no need to initialize the dump data with zeros.
data is allocated with vzalloc, so it's already zero-filled.
More importantly, the memset is harmful, because dump->len (the length

block all QPs opened by the VF, by programming the UPDATE_QP command to drop
all RX & TX traffic to/from these QPs. Operates only in VST mode.

Within VST mode, enable modifying the vlan and/or qos
for a VF without requiring unbind/rebind.
This requires firmware which supports the UPDATE_QP command.
(If the command is not available, we fall back to requiring
unbind/bind to activate these changes).
To avoid race conditions with modify-qp on QPs that are affected
by update-qp, this operation is performed on the comm_wq.
If the update operation succeeds for all the necessary QPs, a
vlan_unregister is performed for the abandoned vlan id.

This makes the error handling much more simpler than open-coding everything and
in addition makes the probe function smaller an tidier.

As reported by "kbuild test robot" there were some errors and warnings
on attempt to build kernel with "make ARCH=powerpc allmodconfig".
And this patch addresses both errors and warnings.
Below is a list of introduced changes:
1. Fix compile-time errors (misspellings in "dma_unmap_single") on PPC.
2. Use DMA address instead of "skb->data" as a pointer to data buffer.
This fixed warnings on pointer to int conversion on 64-bit systems.
3. Re-implemented initial allocation of Rx buffers in "arc_emac_open" in
the same way they're re-allocated during operation (receiving packets).
So once again DMA address could be used instead of "skb->data".
4. Explicitly use EMAC_BUFFER_SIZE for Rx buffers allocation.

When the EEH error is the result of a fenced host bridge, MMIO accesses
can be very slow (milliseconds) to timeout and return all 1's,
thus causing the driver various timeout loops to take way too long and
trigger soft-lockup warnings (in addition to taking minutes to recover).
It might be worthwhile to check if for any of these cases, ffffffff is
a valid possible value, and if not, bail early since that means the HW
is either gone or isolated. In the meantime, checking that the PCI channel
is offline would be workaround of the problem.
