Replace dev_kfree_skb with dev_kfree_skb_any in mv643xx_eth_xmit and
txq_submit_skb that can be called in hard irq and other contexts,
on paths where the skbs are dropped.

When using phydev, it should be phy_start/phy_stop'ed properly. This
driver doesn't do that, so add the corresponding calls to port_start/

Instead of open-coding a PHY reset through the MII BMCR register, use
phy_init_hw() which does that for us and will also make sure that PHY
fixups are applied if required. We also remove a call to phy_reset()
due to the following sequence of calls in the driver:
phy_scan()
-> phy_connect()
-> phy_connect_direct()
-> phy_attach_direct()
-> phy_init_hw()
and we only have a call to phy_init() after phy_scan().

Commit cc9d4598 'net: mv643xx_eth: use of_phy_connect if phy_node
present' made the call to phy_scan optional, if the DT has a link to
the phy node.
However phy_scan has the side effect of calling phy_addr_set, which
writes the phy MDIO address to the ethernet controller. If phy_addr_set
is not called, and the bootloader has not set the correct address then
the driver will fail to function.
Tested on Kirkwood.

The periodic statistics timer gets started at port _probe() time, but
is stopped on _stop() only. In a modular environment, this can cause
the timer to access already deallocated memory, if the module is unloaded
without starting the eth device. To fix this, we add the timer right
before the port is started, instead of at _probe() time.

The change set of 4305b541 "[SK_BUFF]: Convert skb->end to sk_buff_data_t"
converted skb->end from pointer to sk_buff_data_t.
The pointed value should be accessed via skb_end_pointer().
Since arm or ppc arch doesn't define NET_SKBUFF_DATA_USES_OFFSET,
skb->end is effectively pointer. So it doesn't cause a real problem.
But this patch is good for consistency.

Ethernet controllers found on Kirkwood SoCs not only suffer from loosing
MAC address register contents on clock gating but also some important
registers are reset to values that would break ethernet. This patch
clears the CLK125_BYPASS_EN bit for DT enabled Kirkwood only by using
of_device_is_compatible() instead of #ifdefs. Non-DT Kirkwood is not
affected as it installs a clock gating workaround because of the MAC
address issue above. Other Orion SoCs do not suffer from register reset,
do not have the bit in question, or do not have the register at all.
Moreover, system controllers on PPC using this driver should also be
protected from clearing that bit.

This patch converts the Marvell MV643XX ethernet driver to use the
Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms
registering the Marvell MV643XX ethernet driver are also updated to
register a Marvell Orion MDIO driver. This driver voluntarily overlaps
with the Marvell Ethernet shared registers because it will use a subset
of this shared register (shared_base + 0x4 to shared_base + 0x84). The
Ethernet driver is also updated to look up for a PHY device using the
Orion MDIO bus driver.
For ARM and PowerPC we register a single instance of the "mvmdio" driver
in the system like it used to be done with the use of the "shared_smi"
platform_data cookie on ARM.
Note that it is safe to register the mvmdio driver only for the "ge00"
instance of the driver because this "ge00" interface is guaranteed to
always be explicitely registered by consumers of
arch/arm/plat-orion/common.c and other instances (ge01, ge10 and ge11)
were all pointing their shared_smi to ge00. For PowerPC the in-tree
Device Tree Source files mention only one MV643XX ethernet MAC instance
so the MDIO bus driver is registered only when id == 0.

microcontroller inside the qnap that WOL should be enabled by sending

The flags argument of the phy_{attach,connect,connect_direct} functions
is then used to assign a struct phy_device dev_flags with its value.
All callers but the tg3 driver pass the flag 0, which results in the
underlying PHY drivers in drivers/net/phy/ not being able to actually
use any of the flags they would set in dev_flags. This patch gets rid of
the flags argument, and passes phydev->dev_flags to the internal PHY
library call phy_attach_direct() such that drivers which actually modify
a phy device dev_flags get the value preserved for use by the underlying
phy driver.

Over time, skb recycling infrastructure got litle interest and
many bugs. Generic rx path skb allocation is now using page
fragments for efficient GRO / TCP coalescing, and recyling
a tx skb for rx path is not worth the pain.
Last identified bug is that fat skbs can be recycled
and it can endup using high order pages after few iterations.
With help from Maxime Bizon, who pointed out that commit
87151b8689d (net: allow pskb_expand_head() to get maximum tailroom)
introduced this regression for recycled skbs.
Instead of fixing this bug, lets remove skb recycling.
Drivers wanting really hot skbs should use build_skb() anyway,
to allocate/populate sk_buff right before netif_receive_skb()

The clk patches added code to get and enable clocks in the
respective driver probe functions. If the probe function failed
for some reason after enabling the clock, the clock was not
disabled again in many cases.

Commit 452503ebc (ARM: Orion: Eth: Add clk/clkdev support.) broke
the building of the driver on architectures which don't have clk
support. In particular PPC32 Pegasos which uses this driver.
Add #ifdef around the clk API usage.

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.
For example, this cast:
int y;
int *p = (int *)&y;
I used the coccinelle script below to find and remove these
unnecessary casts. I manually removed the conversions this
script produces of casts with __force, __iomem and __user.
@@
type T;
T *p;
@@
- (T *)p
+ p
A function in atl1e_main.c was passed a const pointer
when it actually modified elements of the structure.
Change the argument to a non-const pointer.
A function in stmmac needed a __force to avoid a sparse
warning. Added it.

Pull arm-soc clock driver changes from Olof Johansson:
"The new clock subsystem was merged in linux-3.4 without any users,
this now moves the first three platforms over to it: imx, mxs and
spear.
The series also contains the changes for the clock subsystem itself,
since Mike preferred to have it together with the platforms that
require these changes, in order to avoid interdependencies and
conflicts."
Fix up trivial conflicts in arch/arm/mach-kirkwood/common.c (code
removed in one branch, added OF support in another) and
drivers/dma/imx-sdma.c (independent changes next to each other).

The t_clk is moved from the shared part of the ethernet driver into
the per port section. Each port can have its own gated clock, which it
needs to enable/disable, as oppossed to there being one clock shared
by all ports. In practice, only kirkwood supports this at the moment.

Remove all #inclusions of asm/system.h preparatory to splitting and killing
it. Performed with the following command:
perl -p -i -e 's!^#\s*include\s*<asm/system[.]h>.*\n!!' `grep -Irl '^#\s*include\s*<asm/system[.]h>' *`

These statistics helped me a lot while searching who is losing
packets in my setup.
I added these stats to MIB group since they are very similar,
but just in other registers.
I have tested this patch on 88F6281 SoC.
