ASoC: Updates for v3.15

Quite a busy release for ASoC this time, more on janitorial work than
exciting new features but welcome nontheless:

 - Lots of cleanups from Takashi for enumerations; the original API for
   these was error prone so he's refactored lots of code to use more
   modern APIs which avoid issues.
 - Elimination of the ASoC level wrappers for I2C and SPI moving us
   closer to converting to regmap completely and avoiding some
   randconfig hassle.
 - Provide both manually and transparently locked DAPM APIs rather than
   a mix of the two fixing some concurrency issues.
 - Start converting CODEC drivers to use separate bus interface drivers
   rather than having them all in one file helping avoid dependency
   issues.
 - DPCM support for Intel Haswell and Bay Trail platforms.
 - Lots of work on improvements for simple-card, DaVinci and the Renesas
   rcar drivers.
 - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the
   CSR SiRF SoC.

ASoC: Updates for v3.15

This is mostly a few additional fixes from Lars-Peter, a new driver and
cleaning up a git failure with merging the Intel branch (combined with
an xargs failure to pay attention to error codes).  The history lists a
bunch of additional commits for the branch but the content of those
commits is actually present already but not recorded in history due to
git failing.  Unfortunately xargs is used in the merge script and it
doesn't do a good job of noticing errors from the commands it invokes.

Eric W. Biederman says:

====================
Using dev_kfree/consume_skb_any for functions called in multiple contexts

These changes are a result of walking through the network drivers
supporting netpoll and verifying the code paths that netpoll can cause
to be called in hard irq context use an appropriate flavor of
kfree_skb.  Either dev_kfree_skb_any or dev_consume_skb_any.

Since my last pass at this I have become aware of the small differences
between dev_kfree_skb_any and dev_consume_skb_any.
net/core/drop_monitor.c reports the dev_kfree_skb_any as a drop and
while being quite about the second.  With the weird twist that
dev_kfree_skb is unintuitively consume_skb.

As netpoll now calls the napi poll function with budget == 0, pieces of
a drivers the napi poll function that don't run when budget == 0 have
been ignored.

The most interesting change is to the atl1c which tried unsuccesfully to
tell one of it's functions which context it is called in so that it
could call dev_kfree_skb_irq or dev_kfree_skb as appropriate.  I have
just removed the extra parameter and called dev_consume_skb_any.

At 54 separate changes I will post each change as a separate patch (so
they can be reviewed) but for general sanity sake I have gathered them
all into a git branch for easy acces.

Revert "xen-netback: Aggregate TX unmap operations"

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.

Merge branch 'for-davem' of 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.

tick: Remove code duplication in tick_handle_periodic()

tick_handle_periodic() is calling ktime_add() at two places, first before the
infinite loop and then at the end of infinite loop. We can rearrange code a bit
to fix code duplication here.

It looks quite simple and shouldn't break anything, I guess :)

mlx4: Use actual number of PCI functions (PF + VFs) for alias GUID logic

The code which is dealing with SRIOV alias GUIDs in the mlx4 IB driver has some
logic which operated according to the maximal possible active functions (PF + VFs).

After the single port VFs code integration this resulted in a flow of false-positive
warnings going to the kernel log after the PF driver started the alias GUID work.

Fix it by referring to the actual number of functions.
