363c2cd657 at86rf230: fix irq setup
Commit 8eba0eefae ("at86rf230: remove irq_type in
request_irq") removed the trigger configuration when requesting an irq,
and instead relied on the interrupt trigger to be properly configured
already. This does not seem to be an assumption that can be safely made,
since boards disable all interrupt triggers on boot.

On these boards, force the irq to trigger on rising edge, which is also
the default for the chip.

Pull i2c new drivers from Wolfram Sang:
 "Here is a pull request from i2c hoping for the "new driver" rule.

  Originally, I wanted to send this request during the merge window, but
  code checkers with very recent additions complained, so a few fixups
  were needed.  So, some more time went by and I merged rc1 to get a
  stable base"

So the "new driver" rule is really about drivers that people absolutely
need for the kernel to work on new hardware, which is not so much the
case for i2c.  So I considered not pulling this, but eventually
relented.

Just for FYI: the whole (and only) point of "new drivers" is not that
new drivers cannot regress things (they can, and they have - by
triggering badly tested code on machines that never triggered that code
before), but because they can bring to life machines that otherwise
wouldn't be useful at all without the drivers.

So the new driver rule is for essential things that actual consumers
would care about, ie devices like networking or disk drivers that matter
to normal people (not server people - they run old kernels anyway, so
mainlining new drivers is irrelevant for them).

3acc74619b net: huawei_cdc_ncm: increase command buffer size
Messages from the modem exceeding 256 bytes cause communication
failure.

The WDM protocol is strictly "read on demand", meaning that we only
poll for unread data after receiving a notification from the modem.
Since we have no way to know how much data the modem has to send,
we must make sure that the buffer we provide is "big enough".
Message truncation does not work. Truncated messages are left unread
until the modem has another message to send.  Which often won't
happen until the userspace application has given up waiting for the
final part of the last message, and therefore sends another command.

With a proper CDC WDM function there is a descriptor telling us
which buffer size the modem uses. But with this vendor specific
implementation there is no known way to calculate the exact "big
enough" number.  It is an unknown property of the modem firmware.
Experience has shown that 256 is too small.  The discussion of
this failure ended up concluding that 512 might be too small as
well. So 1024 seems like a reasonable value for now.

e6afea0bbf drivers: net: cpsw: fix dual EMAC stall when connected to same switch
In commit 629c9a8fd0 (drivers: net: cpsw: Add
default vlan for dual emac case also), api cpsw_add_default_vlan() also
changes the port vlan which is required to seperate the ports which results
in the following behavior

In Dual EMAC mode, when both the Etnernet connected is connected to same
switch, it creates a loop in the switch and when a broadcast packet is
received it is forwarded to the other port which stalls the whole switch
and needs a reset/power cycle to the switch to recover. So intead of using
the api, add only the default VLAN entry in dual EMAC case.

ce58725fec xen-netfront: recreate queues correctly when reconnecting
When reconnecting to the backend (after a resume/migration, for example),
a different number of queues may be required (since the guest may have
moved to a different host with different capabilities).  During the
reconnection the old queues are torn down and new ones created.

Introduce xennet_create_queues() and xennet_destroy_queues() that fixes
three bugs during the reconnection.

- The old info->queues was leaked.
- The old queue's napi instances were not deleted.
- The new queue's napi instances were left disabled (which meant no
  packets could be received).

The xennet_destroy_queues() calls is deferred until the reconnection
instead of the disconnection (in xennet_disconnect_backend()) because
napi_disable() might sleep.

13a56b4493 net: phy: at803x: Add support for hardware reset
The AT8030 will enter a FIFO error mode if a packet is transmitted while
the cable is unplugged. This hardware issue is acknowledged by the
vendor, and the only proposed solution is to conduct a hardware reset
via the external pin each time the link goes down. There is apparantly
no way to fix up the state via the register set.

This patch adds support for reading a 'reset-gpios' property from the DT
node of the PHY. If present, this gpio is used to apply a hardware reset
each time a 'link down' condition is detected. All relevant registers
are read out before, and written back after the reset cycle.

Doing this every time the link goes down might seem like overkill, but
there is unfortunately no way of figuring out whether the PHY is in
such a lock-up state. Hence, this is the only way of reliably fixing up
things.

====================
Intel Wired LAN Driver Updates 2014-06-20

This series contains updates to i40e and i40evf.

Anjali provides an update to the registers to handle the updates from the
hardware.  Also provides a fix so that we do not try to access the rings
through the qvectors at the time of freeing the qvectors.

Jesse provides a workaround for some older NVM versions where the NVM
was not filling in the GLQF_HKEY register, so made sure that the
critical register is initialized.

Michal provides a fix to reset the head and tail on admin queue
initialization where head and tail are not reset by the hardware.

Neerav adds a helper routine that would wait for the Rx/Tx queue to reach
the enable or disable state that is requested.  Also provides a fix
to the debugfs command "lldp get remote" which was dumping the local
LLDPDU instead of the peer's LLDPDU.  Fixed a bug when all the Tx hang
recovery mechanisms have failed and the driver tries to bring down the
interface in the interrupt context.

Shannon provides a patch to clear the Virtual Ethernet Bridge (VEB) stats
when the PF stats are cleared.  Also cleans the service tasks so that
they do not run while a reset is in progress.

Mitch fixes an issue in i40evf_get_rxfh() where only fifteen registers
were being read instead of all sixteen.

Carolyn provides a change to the RSS configuration to set table size and
write to the hardware to confirm the RSS table size being used.

Kamil makes a change to the admin queue debug prints so that they will not
cause segmentation faults in some of our tool applications.

7cbcb9d46f ARM: EXYNOS: Don't rely on firmware's secondary_cpu_start for mcpm
On exynos mcpm systems the firmware is hardcoded to jump to an address
in SRAM (0x02073000) when secondary CPUs come up.  By default the
firmware puts a bunch of code at that location.  That code expects the
kernel to fill in a few slots with addresses that it uses to jump back
to the kernel's entry point for secondary CPUs.

Originally (on prerelease hardware) this firmware code contained a
bunch of workarounds to deal with boot ROM bugs.  However on all
shipped hardware we simply use this code to redirect to a kernel
function for bringing up the CPUs.

Let's stop relying on the code provided by the bootloader and just
plumb in our own (simple) code jump to the kernel.  This has the nice
benefit of fixing problems due to the fact that older bootloaders
(like the one shipped on the Samsung Chromebook 2) might have put
slightly different code into this location.

Once suspend/resume is implemented for systems using exynos-mcpm we'll
need to make sure we reinstall our fixed up code after resume.  ...but
that's not anything new since IRAM (and thus the address of the
mcpm_entry_point) is lost across suspend/resume anyway.
