bc1f44709c net: make ndo_get_stats64 a void function
The network device operation for reading statistics is only called
in one place, and it ignores the return value. Having a structure
return value is potentially confusing because some future driver could
incorrectly assume that the return value was used.

Fix all drivers with ndo_get_stats64 to have a void function.

5580373fb2 SSB / B44: fix WOL for BCM4401
Wake On Lan was not working on laptop DELL Vostro 1500.
If WOL was turned on, BCM4401 was powered up in suspend mode. LEDs blinked.
But the laptop could not be woken up with the Magic Packet. The reason for
that was that PCIE was not enabled as a system wakeup source and
therefore the host PCI bridge was not powered up in suspend mode.
PCIE was not enabled in suspend by PM because no child devices were
registered as wakeup source during suspend process.
On laptop BCM4401 is connected through the SSB bus, that is connected to the
PCI-Express bus. SSB and B44 did not use standard PM wakeup functions
and did not forward wakeup settings to their parents.
To fix that B44 driver enables PM wakeup and registers new wakeup source
using device_set_wakeup_enable(). Wakeup is automatically reported to the parent SSB
bus via power.wakeup_path. SSB bus enables wakeup for the parent PCI bridge, if there is any
child devices with enabled wakeup functionality. All other steps are
done by PM core code.

86f4ea63e6 b44: add phylib support
Most of the older home routers based on the Broadcom BCM47XX SoC series
are using a MAC that is supported by b44. On most of these routers not
the internal PHY of this MAC core is used, but a switch sometimes on an
external chip or integrated into the same SoC as the Ethernet core.
For this switch a special PHY driver is needed which should not be
integrated into b44 as the same switches are also used by other
Broadcom home networking SoCs which are using different Ethernet MAC
drivers. This was tested with the b53 switch driver which is currently
on its way to mainline.

If the internal PHY is not used, b44 will now search on the MDIO bus
for a phy and use the Linux phylib subsystem to register a driver.
Support for the internal PHY must stay here, because there are some
device which are suing the internal phy.

With this patch we scan the mdio bus when the sprom or nvram says that
the PHY address is 30, if a PHY was found at this address b44 uses it.

This was tested with a BCM4704, BCM4712 and BCM5354.

d61941952d b44: check register instead of PHY address to detect external PHY
The Ethernet core supported by b44 supports an internal PHY integrated
into the mac core, which is supported by the b44 driver and an external
PHY to which the mac core is connected. This external PHY could be a
switch connected through MII, which is often the case when this core is
used on home routers. The usage of an external PHY was assumed when the
PHY address 30 was used and an internal PHY was assumed when the PHY
address was different. To verify that b44_phy_reset() was called and
checked if it worked, otherwise PHY address 30 was assumed, an external
PHY. It is better to check the register which says which PHY is
connected to the MAC instead of checking the PHY address.
The interface to an external PHY was only activated when this register
was set.

This also changes B44_FLAG_INTERNAL_PHY to B44_FLAG_EXTERNAL_PHY, it is
easier to check.

8ceafbfa91 Merge branch 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm
Pull DMA mask updates from Russell King:
 "This series cleans up the handling of DMA masks in a lot of drivers,
  fixing some bugs as we go.

  Some of the more serious errors include:
   - drivers which only set their coherent DMA mask if the attempt to
     set the streaming mask fails.
   - drivers which test for a NULL dma mask pointer, and then set the
     dma mask pointer to a location in their module .data section -
     which will cause problems if the module is reloaded.

  To counter these, I have introduced two helper functions:
   - dma_set_mask_and_coherent() takes care of setting both the
     streaming and coherent masks at the same time, with the correct
     error handling as specified by the API.
   - dma_coerce_mask_and_coherent() which resolves the problem of
     drivers forcefully setting DMA masks.  This is more a marker for
     future work to further clean these locations up - the code which
     creates the devices really should be initialising these, but to fix
     that in one go along with this change could potentially be very
     disruptive.

  The last thing this series does is prise away some of Linux's addition
  to "DMA addresses are physical addresses and RAM always starts at
  zero".  We have ARM LPAE systems where all system memory is above 4GB
  physical, hence having DMA masks interpreted by (eg) the block layers
  as describing physical addresses in the range 0..DMAMASK fails on
  these platforms.  Santosh Shilimkar addresses this in this series; the
  patches were copied to the appropriate people multiple times but were
  ignored.

  Fixing this also gets rid of some ARM weirdness in the setup of the
  max*pfn variables, and brings ARM into line with every other Linux
  architecture as far as those go"

7341a73c12 b44: use netdev_alloc_skb_ip_align()
Without this patch b44 always allocates the 2 bytes needed for aligned
access on every platform, now it uses netdev_alloc_skb_ip_align().

b2adaca92c ethernet: Remove unnecessary alloc/OOM messages, alloc cleanups
alloc failures already get standardized OOM
messages and a dump_stack.

Convert kzalloc's with multiplies to kcalloc.
Convert kmalloc's with multiplies to kmalloc_array.
Fix a few whitespace defects.
Convert a constant 6 to ETH_ALEN.
Use parentheses around sizeof.
Convert vmalloc/memset to vzalloc.
Remove now unused size variables.

1dd06ae8db drivers/net: fix up function prototypes after __dev* removals
The __dev* removal patches for the network drivers ended up messing up
the function prototypes for a bunch of drivers.  This patch fixes all of
them back up to be properly aligned.

Bonus is that this almost removes 100 lines of code, always a nice
surprise.

acfa9e94e2 net: dont use __netdev_alloc_skb for bounce buffer
commit a1c7fff7e1 (net: netdev_alloc_skb() use build_skb()) broke b44 on
some 64bit machines.

It appears b44 and b43 use __netdev_alloc_skb() instead of alloc_skb()
for their bounce buffers.

There is no need to add an extra NET_SKB_PAD reservation for bounce
buffers :

- In TX path, NET_SKB_PAD is useless

- In RX path in b44, we force a copy of incoming frames if
  GFP_DMA allocations were needed.
