The usual straighforward failure to check for dma_mapping_error after a map
operation is completed.

This patch should fix it, the reporter wandered off after filing this bz:
https://bugzilla.redhat.com/show_bug.cgi?id=954170

and I don't have hardware to test, but the fix is pretty straightforward, so I
figured I'd post it for review.

Linus Torvalds 496322bc91 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
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 0a4db187a9 ("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

The driver is comprised of two kernel modules: mlx5_ib and mlx5_core.
This partitioning resembles what we have for mlx4, except that mlx5_ib
is the pci device driver and not mlx5_core.

mlx5_core is essentially a library that provides general functionality
that is intended to be used by other Mellanox devices that will be
introduced in the future.  mlx5_ib has a similar role as any hardware
device under drivers/infiniband/hw.

Ben Hutchings 734d4e159b sfc: Fix memory leak when discarding scattered packets
Commit 2768935a46 ('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.

Linus Torvalds 74b9272bbe Device tree updates for v3.11
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.

   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

 - Handle sparse GPIO ranges passing a list of disparate pins, and

 - Make the sunxi (AllWinner) driver handle external interrupts.
 
 - Make it possible for pinctrl-single to handle the case where

This requires firmware which supports the UPDATE_QP command.
(If the command is not available, we fall back to requiring

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.

Alexey Brodkin a4a1139b24 arc_emac: fix compile-time errors & warnings on PPC64
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.

Gavin Shan 6d446ec32f net/tg3: Avoid delay during MMIO access
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.

Eric Dumazet 51151a16a6 mlx4: allow order-0 memory allocations in RX path
Signed-off-by: Eric Dumazet <edumazet@google.com>

mlx4 exclusively uses order-2 allocations in RX path, which are
likely to fail under memory pressure.

We therefore drop frames more than needed.

This patch tries order-3, order-2, order-1 and finally order-0
allocations to keep good performance, yet allow allocations if/when
memory gets fragmented.

By using larger pages, and avoiding unnecessary get_page()/put_page()
on compound pages, this patch improves performance as well, lowering
false sharing on struct page.

Also use GFP_KERNEL allocations in initialization path, as allocating 12
MB (390 order-3 pages) can easily fail with GFP_ATOMIC.

David S. Miller 3bae9db9aa Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfc-next
Ben Hutchings says:

====================
1. Make EEH recovery work when using legacy interrupts, from Alexandre
   Rames.

2. Enable accelerated RFS for VLAN-tagged flows, from Andy Lutomirski.

3. Improve performance for non-TCP (and particularly UDP) traffic, which
   regressed in 3.10 when we switched to always allocating paged RX
   buffers.  Partly by Jon Cooper.

4. Some minor bug fixes to IOMMU detection, timestamping capabilities,
   and IRQ cleanup on the probe failure path.

I've dropped the RX skb cache, which improved some benchmarks but
perhaps needs some reworking to be more generally useful.

Ben Hutchings 1899c111a5 sfc: Fix IRQ cleanup in case of a probe failure
The lifetime of an irq_cpu_rmap is odd: we have to allocate it before
installing IRQ handlers and free it before removing the IRQ handlers.
As a result of this asymmetry, it was omitted from some failure paths.

On another failure path, we could try to remove IRQ handlers we
had not yet installed.

Move the irq_cpu_rmap allocation and freeing alongside IRQ handler
installation and removal, in efx_nic_{init,fini}_interrupts().
Count the number of IRQ handlers successfully installed and only
remove those on the failure path.

Ben Hutchings e79255de85 sfc: Do not pass non-TCP packets into GRO code
GRO can handle non-TCP packets and pass them up without coalescing,
but it has to do some extra work to parse the packet which we can
bypass using the hardware parse result.  (This condition yields a
false negative for TCP/IPv6 packets received by Falcon, but its
performance is already poor in that case due to lack of checksum
offload.)

Due to obviously missing braces, EESR.TABT (transmit abort) interrupt may be
reported even if it hasn't happened, just when EESR.TWB (transmit descriptor
write-back) interrupt happens. Luckily (?), EESR.TWB is disabled by the driver
via the TRIMD register and all the interrupt masks, so that transmit abort is
never actually logged...

and sh_eth_error() handles it but it's not present in any initializer/assignment
of the 'eesr_err_check' field of 'struct sh_eth_cpu_data'. This leads to that
interrupt not being handled and cleared, and finally to disabling IRQ and the
driver being non-functional.

mentioned field to contain the EESR.RFE bit. Remove useless backslashes from the
initializers, while at it.
