Several cases of overlapping changes.
The xfrm6_output.c has a bug fix which overlaps the renaming
of skb->local_df to skb->ignore_df.
In the Altera TSE driver cases, the register access cleanups
in net-next overlapped with bug fixes done in net.
Similarly a bug fix to send ALB packets in the bonding driver using
the right source address overlaps with cleanups in net-next.

Some Ethernet MACs have a "fixed link", and are not connected to a
normal MDIO-managed PHY device. For those situations, a Device Tree
binding allows to describe a "fixed link" using a special PHY node.
This patch adds:
* A documentation for the fixed PHY Device Tree binding.
* An of_phy_is_fixed_link() function that an Ethernet driver can call
on its PHY phandle to find out whether it's a fixed link PHY or
not. It should typically be used to know if
of_phy_register_fixed_link() should be called.
* An of_phy_register_fixed_link() function that instantiates the
fixed PHY into the PHY subsystem, so that when the driver calls
of_phy_connect(), the PHY device associated to the OF node will be
found.
These two additional functions also support the old fixed-link Device
Tree binding used on PowerPC platforms, so that ultimately, the
network device drivers for those platforms could be converted to use
of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
of_phy_connect_fixed_link(), while keeping compatibility with their
respective Device Tree bindings.

Seems like we've had more fixes than usual this release cycle, but
there's nothing in particular that we're doing differently. Perhaps it's
just one of those cycles where more people are finding more regressions
(and/or that the latency of when people actually test what's been in
the tree for a while is catching up so that we get the bug reports now).
The bigger changes here are are for TI and Marvell platforms:
* Timing changes for GPMC (generic localbus) on OMAP causing some largeish
DTS deltas.
* Fixes to window allocation on PCI for mvebu touching drivers/ stuff. Patches
have acks from subsystem maintainers where needed.
* A fix from Thomas for a botched DT conversion in drivers/edma.
There's a handful of other fixes for the above platforms as well as sunxi,
at91, i.MX. I also included a MAINTAINER update for Broadcom, and a trivial
move of a binding doc.

driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2
Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"
Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

pull request: wireless-next 2014-05-02
Please pull this batch of updates intended for the 3.16 stream...
For the mac80211 bits, Johannes says:
"In this round we have a large number of small features and
improvements from people too numerous to list here. The only really
bit thing is Michał and Luca's CSA work (including changing how
interface combination verification is done)."
For the Bluetooth bits, Gustavo says:
"Here goes some patches for the -next release. There is nothing
really special for this pull request, just a bunch of refactors,
fixes and clean ups."
For the ath10k/ath6kl bits, Kalle says:
"For ath6kl Kalle fixed a bunch of checkpatch warnings.
In ath10k we had more changes, major ones being:
* fix memory allocation failures after a firmware crash (Michal)
* some rework of DFS configuration to enable it correctly in all cases
(Michal)
* add a new firmware crash option to make it possible to crash 10.1
firmware for testing purposes (Marek P)
* fix RTS/CTS protection in certain cases (Marek K)
* fix wrong RSSI and rate reporting in some cases (Janusz)
* fix firmware stats reporting (Chun, Ben & Bartosz)"
For the iwlwifi bits, Emmanuel says:
"I have here a bunch of unrelated things. I disabled support for
-7.ucode which means that I can removed a lot of code. Eliad has
a brand new feature: we reduce the Tx power when the link allows -
this reduces our power consumption. The regular changes in power and
scan area. One interesting thing though is the patches from Johannes,
we have now GRO which allows to increase our throughput in TCP Rx. The
main advantage is that it reduces the number of TCP Acks - these TCP
Acks are completely useless when we are using A-MPDU since the first
packet of the A-MPDU generates a TCP Ack which is made obsolete by
the next packets."
Along with that, there are a variety of updates to b43, mwifiex,
rtl8180 and wil6210 drivers and a handful of other updates here
and there.
Please let me know if there are problems!

clockevent fixes for 3.15 from Daniel Lezcano:
* Lorenzo Pieralizi fixed an issue with the arch_arm_timer where the
C3STOP flag for all the arch can cause some trouble by setting the
flag only if the power domain is not always on
* Alexander Shiyan fixed a compilation by changing the init function
to the right prototype
This is another great example of trainwreck engineering:
commit 2646a0e529 (ARM: edma: Add EDMA crossbar event mux support)
added support for using EDMA on peripherals which have no direct EDMA
event mapping.
The code compiles and does not explode in your face, but that's it.
1) Reading an u16 array from an u32 device tree array simply does not
work. Even if the function is named "edma_of_read_u32_to_s16_array".
It merily calls of_property_read_u16_array. So the resulting 16bit
array will have every other entry = 0.
2) The DT entry for the xbar registers related to xbar has length 0x10
instead of the real length: 0xfd0 - 0xf90 = 0x40.
Not a real problem as it does not cross a page boundary, but
wrong nevertheless.
3) But none of this matters as the mapping never happens:
After reading nonsense edma_of_read_u32_to_s16_array() invalidates
the first array entry pair, so nobody can ever notice the
braindamage by immediate explosion.
Seems the QA criteria for this code was solely not to explode when
someone adds edma-xbar-event-map entries to the DT. Goal achieved,
congratulations!
Not really helpful if someone wants to use edma on a device which
requires a xbar mapping.
Fix the issues by:
- annotating the device tree entry with "/bits/ 16" as documented in
the of_property_read_u16_array kernel doc
- make the size of the xbar register mapping correct
- invalidating the end of the array and not the start
This convoluted mess wants to be completely rewritten as there is no
point to keep the xbar_chan array memory and the iomapping of the xbar
regs around forever. Marking the xbar mapped channels as used should
be done right there.
But that's a different issue and this patch is small enough to make it
work and allows a simple backport for stable.

ARM arch timers are tightly coupled with the CPU logic and lose context
on platform implementing HW power management when cores are powered
down at run-time. Marking the arch timers as C3STOP regardless of power
management capabilities causes issues on platforms with no power management,
since in that case the arch timers cannot possibly enter states where the
timer loses context at runtime and therefore can always be used as a high
resolution clockevent device.
In order to fix the C3STOP issue in a way compliant with how real HW
works, this patch adds a boolean property to the arch timer bindings
to define if the arch timer is managed by an always-on power domain.
This power domain is present on all ARM platforms to date, and manages
HW that must not be turned off, whatever the state of other HW
components (eg power controller). On platforms with no power management
capabilities, it is the only power domain present, which encompasses
and manages power supply for all HW components in the system.
If the timer is powered by the always-on power domain, the always-on
property must be present in the bindings which means that the timer cannot
be shutdown at runtime, so it is not a C3STOP clockevent device.
If the timer binding does not contain the always-on property, the timer is
assumed to be power-gateable, hence it must be defined as a C3STOP
clockevent device.

The aggresive load balancing causes packet re-ordering as active
flows are moved from a slave to another within the group. Sometime
this aggresive lb is not necessary if the preference is for less
re-ordering. This parameter if used with value "0" disables
this dynamic flow shuffling minimizing packet re-ordering. Of course
the side effect is that it has to live with the static load balancing
that the hashing distribution provides. This impact is less severe if
the correct xmit-hashing-policy is used for the tlb setup.
The default value of the parameter is set to "1" mimicing the earlier
behavior.
Ran the netperf test with 200 stream for 1 min between two hosts with
4x1G trunk (xmit-lb mode with xmit-policy L3+4) before and after these
changes. Following was the command used for those 200 instances -

Re-organized the xmit function for the lb mode separating tlb xmit
from the alb mode. This will enable use of the hashing policies
like 802.3ad mode. Also extended use of xmit-hash-policy to tlb mode.
Now the tlb-mode defaults to BOND_XMIT_POLICY_LAYER2 if the xmit policy
module parameter is not set (just like 802.3ad, or Xor mode).

Added a new ancillary load (bpf call in eBPF parlance) that produces
a 32-bit random number. We are implementing it as an ancillary load
(instead of an ISA opcode) because (a) it is simpler, (b) allows easy
JITing, and (c) seems more in line with generic ISAs that do not have
"get a random number" as a instruction, but as an OS call.
The main use for this ancillary load is to perform random packet sampling.
