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.

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.

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

- New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the

When ir_dev_scope_init() is called via a rootfs initcall it
will check for irq_remapping_enabled before it calls
(indirectly) into dmar_acpi_dev_scope_init() which uses the
dmar_tbl pointer without any checks.
The AMD IOMMU driver also sets the irq_remapping_enabled
flag which causes the dmar_acpi_dev_scope_init() function to
be called on systems with AMD IOMMU hardware too, causing a
boot-time kernel crash.

If during a SPI transfer with len larger than PCH_MAX_FIFO_DEPTH and the
IRQ handler happens to be called when the transmit FIFO is already empty,
and SPSR_FI_BIT is set consequently, the message
"spi_master spi32766: pch_spi_handler_sub : Transfer is not completed"
is spammed to the systemlog, because tx_index has already increased
further due to the next bytes to be written. This case is uncritical as

Many couples of CPU/CODEC DAI links may be described in the DT
thanks to 'simple-audio-card,dai-link' containers.

The DAI link array and the properties (fmt, sysclk slots) are
hard-coded for a single CPU / CODEC link.
This patch dynamically allocates the DAI link array and the
properties with the aim of supporting many DAI links.

spi core will use spi->max_speed_hz as transfer speed if the transfer speed was
not set. So we don't need to test t->speed_hz in mcfqspi_transfer_one().

Wolfram Sang pointed out that "efm32,$device" is non-standard. So use the
common scheme and prefix device with "efm32-". The old compatible string
is left in place until arch/arm/boot/dts/efm32* is fixed.

destroy_timer_on_stack() is hardly the right thing for a delayed
work. We leak a tracking object for the work itself when DEBUG_OBJECTS
is enabled.

If a delayed or deferrable work is on stack we need to tell debug
objects that we are destroying the timer and the work. Otherwise we
leak the tracking object.

- memory leak on certain SIGP conditions
- wrong size for idle bitmap (always too big)
- clear local interrupts on initial CPU reset
1 performance improvement
- improve performance with many guests on certain workloads
