Conflicts:
Documentation/devicetree/bindings/net/micrel-ks8851.txt
net/core/netpoll.c
The net/core/netpoll.c conflict is a bug fix in 'net' happening
to code which is completely removed in 'net-next'.
In micrel-ks8851.txt we simply have overlapping changes.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next
John W. Linville says:
====================
Please pull this batch of wireless updates intended for 3.15!
For the mac80211 bits, Johannes says:
"This has a whole bunch of bugfixes for things that went into -next
previously as well as some other bugfixes I didn't want to rush into
3.14 at this point. The rest of it is some cleanups and a few small
features, the biggest of which is probably Janusz's regulatory DFS CAC
time code."
For the Bluetooth bits, Gustavo says:
"One more pull request to 3.15. This is mostly and bug fix pull request, it
contains several fixes and clean up all over the tree, plus some small new
features."
For the NFC bits, Samuel says:
"This is the NFC pull request for 3.15. With this one we have:
- Support for ISO 15693 a.k.a. NFC vicinity a.k.a. Type 5 tags. ISO
15693 are long range (1 - 2 meters) vicinity tags/cards. The kernel
now supports those through the NFC netlink and digital APIs.
- Support for TI's trf7970a chipset. This chipset relies on the NFC
digital layer and the driver currently supports type 2, 4A and 5 tags.
- Support for NXP's pn544 secure firmare download. The pn544 C3 chipsets
relies on a different firmware download protocal than the C2 one. We
now support both and use the right one depending on the version we
detect at runtime.
- Support for 4A tags from the NFC digital layer.
- A bunch of cleanups and minor fixes from Axel Lin and Thierry Escande."
For the iwlwifi bits, Emmanuel says:
"We were sending a host command while the mutex wasn't held. This
led to hard-to-catch races."
And...
"I have a fix for a "merge damage" which is not really a merge
damage: it enables scheduled scan which has been disabled in
wireless.git. Since you merged wireless.git into wireless-next.git,
this can now be fixed in wireless-next.git.
Besides this, Alex made a workaround for a hardware bug. This fix
allows us to consume less power in S3. Arik and Eliad continue to
work on D0i3 which is a run-time power saving feature. Eliad also
contributes a few bits to the rate scaling logic to which Eyal adds his
own contribution. Avri dives deep in the power code - newer firmware
will allow to enable power save in newer scenarios. Johannes made a few
clean-ups. I have the regular amount of BT Coex boring stuff. I disable
uAPSD since we identified firmware bugs that cause packet loss. One
thing that do stand out is the udev event that we now send when the
FW asserts. I hope it will allow us to debug the FW more easily."
Also included is one last iwlwifi pull for a build breakage fix...
For the Atheros bits, Kalle says:
"Michal now did some optimisations and was able to improve throughput by
100 Mbps on our MIPS based AP135 platform. Chun-Yeow added some
workarounds to be able to better use ad-hoc mode. Ben improved log
messages and added support for MSDU chaining. And, as usual, also some
smaller fixes."
Beyond that...
Andrea Merello continues his rtl8180 refactoring, in preparation for
a long-awaited rtl8187 driver. We get a new driver (rsi) for the
RS9113 chip, from Fariya Fatima. And, of course, we get the usual
round of updates for ath9k, brcmfmac, mwifiex, wil6210, etc. as well.

This reverts commit e9275f5e2df1b2098a8cc405d87b88b9affd73e6. This commit is the
last in the netback grant mapping series, and it tries to do more aggressive
aggreagtion of unmap operations. However practical use showed almost no
positive effect, whilst with certain frontends it causes significant performance
regression.

Replace dev_kfree_skb with dev_consume_skb_any in
spider_net_release_tx_chain which can be called in hard irq and other
contexts.
dev_consume_skb_any was choosen as it preserves the current
dev_kfree_skb semantics (dev_kfree_skb is consume_skb) and
is because it is correct most of the time as most packets
will have been successfully transmitted not dropeed.

Replace dev_kfree_skb with dev_consume_skb_any in sc92031_start_xmit

Using dev_consume_skb_any preserves the current semantics (as
dev_kfree_skb is just consume_skb) and since packet drops
are rare is usually accurate.
