Most of these relate to endianness problems, and are purely cosmetic.
But a couple of them were legit -- listen interval parsing and some of
the rate selection code would malfunction on BE systems.
There's still one cosmetic warning remaining, in the (admittedly) ugly
code in cw1200_spi.c. It's there because the hardware needs 16-bit SPI
transfers, but many SPI controllers only operate 8 bits at a time.
If there's a cleaner way of handling this, I'm all ears.

It is possible for two cpu's to race creating vxlan device.
For most cases this is harmless, but the ability to assign "next
avaliable vxlan device" relies on rtnl lock being held across the
whole operation. Therfore two instances of calling:
ip li add vxlan%d vxlan ...
could collide and create two devices with same name.
To fix this defer creation of socket to a work queue, and
handle possible races there. Introduce a lock to ensure that
changes to vxlan socket hash list is SMP safe.

John W. Linville says:
====================
I would guess that this is the last big wireless pull request before
the 3.11 merge window...
Regarding the mac80211 bits, Johannes says:
"I have a number of mesh fixes and improvements from Colleen, Jacob,
Ashok and Thomas, powersave fixes in mac80211 from Alex, improved
management-TX from Antonio, and a few various things, including locking
fixes, from others and myself. Overall though, nothing really stands
out."
As for the iwlwifi bits, Johannes says:
"Emmanuel contributed two AP mode fixes, removed an unused field, fixed a
comment and added a warning for something that shouldn't happen in
practice, and I removed the declaration of a function that doesn't even
exist and cleaned up a small include."
"This time I have a number of cleanups, a small fix from Emmanuel and two
performance improvements that combined reduce our driver's CPU
utilisation as much as 75% in high TX-throughput scenarios."
"These two patches fix two issues with using rfkill randomly during
traffic, which would then cause our driver to stop working and not be
able to recover at all."
Regarding the ath6kl bits, Kalle says:
"Here are few simple patches for ath6kl. We have a suspend crash fix for
USB from Shafi, use of mac_pton(), a compiler warning fix and a fix for
module initialisation error path."
Kalle also sends the biggest single item of note, the new ath10k
driver for Qualcomm Atheros 802.11ac CQA98xx devices.
Included is an NFC pull, of which Samuel says:
"These are the pending NFC patches for the 3.11 merge window.
It contains the pending fixes that were on nfc-fixes (nfc-fixes-3.10-2),
along with a few more for the pn544 and pn533 drivers, the LLCP
disconnection path and an LLCP memory leak.
Highlights for this one are:
- An initial secure element API. NFC chipsets can carry an embedded
secure element or get access to the SIM one. In both cases they
control the secure elements and this API provides a way to discover,
enable and disable the available SEs. It also exports that to
userspace in order for SE focused middleware to actually do something
with them (e.g. payments).
- NCI over SPI support. SPI is the most complex NCI specified transport
layer and we now have support for it in the kernel. The next step will
be to implement drivers for NCI chipsets using this transport like
e.g. bcm2079x.
- NFC p2p hardware simulation driver. We now have an nfcsim driver that
is mostly a loopback device between 2 NFC interfaces. It also
implements the rest of the NFC core API like polling and target
detection. This driver, with neard running on top of it, allows us to
completely test the LLCP, SNEP and Handover implementation without
physical hardware.
- A Firmware update netlink API. Most (All ?) HCI chipsets have a
special firmware update mode where applications can push a new
firmware that will be flashed. We now have a netlink API for providing
that mode to e.g. nfctool."
On top of all that, there are a variety of updates to brcmfmac,
iwlegacy, rtlwifi, wil6210, and the TI wl12xx drivers. As usual,
the bcma and ssb busses get a little love as well, as do a handful
of others here and there.

Due to obviously missing braces, EESR.TABT (transmit abort) interrupt may be
reported even if it hasn't happened, just when EESR.TWB (transmit descriptor
write-back) interrupt happens. Luckily (?), EESR.TWB is disabled by the driver
via the TRIMD register and all the interrupt masks, so that transmit abort is
never actually logged...

EESR.RFE (receive FIFO overflow) interrupt is enabled by the driver on all SoCs
and sh_eth_error() handles it but it's not present in any initializer/assignment
of the 'eesr_err_check' field of 'struct sh_eth_cpu_data'. This leads to that
interrupt not being handled and cleared, and finally to disabling IRQ and the
driver being non-functional.

mentioned field to contain the EESR.RFE bit. Remove useless backslashes from the
