Merge tag 'pci-v3.17-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull DEFINE_PCI_DEVICE_TABLE removal from Bjorn Helgaas:
 "Part two of the PCI changes for v3.17:

    - Remove DEFINE_PCI_DEVICE_TABLE macro use (Benoit Taine)

  It's a mechanical change that removes uses of the
  DEFINE_PCI_DEVICE_TABLE macro.  I waited until later in the merge
  window to reduce conflicts, but it's possible you'll still see a few"

 "Several networking final fixes and tidies for the merge window:

   1) Changes during the merge window unintentionally took away the

   2) Several phy_node reference count bug fixes from Uwe Kleine-König.

   3) Fix ucc_geth build failures, also from Uwe Kleine-König.

   4) Fix klog false positivies when netlink messages go to network
      taps, by properly resetting the network header.  Fix from Daniel
      Borkmann.

   5) Sizing estimate of VF netlink messages is too small, from Jiri
      Benc.

   6) New APM X-Gene SoC ethernet driver, from Iyappan Subramanian.

   7) VLAN untagging is erroneously dependent upon whether the VLAN
      module is loaded or not, but there are generic dependencies that
      matter wrt what can be expected as the SKB enters the stack.
      Make the basic untagging generic code, and do it unconditionally.
      From Vlad Yasevich.

   8) xen-netfront only has so many slots in it's transmit queue so
      linearize packets that have too many frags.  From Zoltan Kiss.

9baa3c34ac PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use
We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines.  This issue was reported by checkpatch.

A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):

// <smpl>

88131a812b amd-xgbe: Perform phy connect/disconnect at dev open/stop
A change added to the mdiobus/phy api added a module_get/module_put
during phy connect/disconnect processing. Currently, the driver
performs a phy connect during module probe and a phy disconnect during
module remove. With the addition of the module_get during phy connect
the amd-xgbe module use count is incremented and can no longer be
unloaded.

Move the phy connect/disconnect from the driver probe/remove functions
to the net_device_ops ndo_open/ndo_stop functions.  This allows the
module use count to be decremented when the device(s) are brought down
and allows the module to be unloaded.

in 64-bit compilation.  Where the value printed is an offset (whose range

cfa50c7811 amd-xgbe: Base AXI DMA cache settings on device tree
The default cache operations for ARM64 were changed during 3.15.
To use coherent operations a "dma-coherent" device tree property
is required.  If that property is not present in the device tree
node then the non-coherent operations are assigned for the device.

Add support to the amd-xgbe driver to assign the AXI DMA cache settings
based on whether the "dma-coherent" property is present in the device
node.  If present, use settings that work with the caches.  If not
present, use settings that do not look at the caches.

  - Change the AXI burst length to 256 bytes (default was 16 bytes which

  - Change the AXI cache settings to write-back/write-allocate which
    allocate cache entries for received packets during the DMA since the
    packet will be processed soon afterwards
  - Combine ioread/iowrite when disabling both the Tx and Rx interrupts
  - Change to processing the Tx/Rx channels in pairs
  - Only recycle the Rx descriptors when a threshold of dirty descriptors
    is reached

f3f128d40c amd-xgbe: Fix debugfs compatibility change with kstrtouint

compatbility by using a base of "0" in the kstrtouint call.
This allowed for entering decimal, hexadecimal or octal as

as hexadecimal.  Additionally, -EIO was returned on error prior
to this change and now it is whatever the error value that is

There is a typo here so we return directly instead of unwinding.

d5c4858237 amd-xgbe: Rename MAX_DMA_CHANNELS to avoid powerpc conflict
MAX_DMA_CHANNELS is defined in asm/scatterlist.h of the powerpc
architecture.  Rename this #define in xgbe.h to avoid the
redefined warning issued during compilation.

1caaab63d3 amd-xgbe: Remove unnecessary include
The include of asm/cputype.h breaks the powerpc build. This
include was accidentally left in from driver debugging and
can be removed.

Conflicts:
	drivers/net/xen-netback/netback.c

A filter bug fix overlapped some cleanups and a conversion
over to some new insn generation macros.

A xen-netback bug fix overlapped the addition of multi-queue
support.

78c8dbb652 hplance: fix ram size in comment
drivers/net/ethernet/amd/hplance.h:
 #define HPLANCE_MEMOFF 0x8000   /* struct lance_init_block */
 #define HPLANCE_NVRAMOFF 0xC008 /* etheraddress as one *nibble* per byte */

The offset of RAM start is 0x8000, the offset of RAM end is 0xC008,
so the RAM size is 16392 bytes.

688c3b0033 net/ariadne: delete unneeded call to netdev_priv
Netdev_priv is an accessor function, and has no purpose if its result is
not used.

A simplified version of the semantic match that fixes this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@ local idexpression x; @@
-x = netdev_priv(...);
... when != x

7ad24ea4bf net: get rid of SET_ETHTOOL_OPS
net: get rid of SET_ETHTOOL_OPS

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
-       SET_ETHTOOL_OPS(dev, ops);
+       dev->ethtool_ops = ops;

Compile tested only, but I'd seriously wonder if this broke anything.

Replace dev_kfree_skb with dev_kfree_skb_any in pcnet32_start_xmit
that can be called in hard irq and other contexts.

dev_kfree_skb_any is used as pcnet32_start_xmit only frees an
skb when it drops a packet during transmit.
