This patch adds a new driver for keypad for Cirrus Logic CLPS711X CPUs.
Target CPU contain keyboard interface which can scan 8 column lines,
so we can read row GPIOs to read status and determine asserted state.

The SDHCI unit used on the Armada 380 and 385 Marvell SoC is similar
to the PXAv3 unit. The only difference is that on Armada 38x, the
PXAv3 unit accesses memory through MBus windows which must be
configured prior to using the device. Without this, DMA would not
work.
In order to achieve this, the sdhci-pxav3 driver is extended with an
additional compatible string "marvell,armada-380-sdhci". When this
compatible string is used, the MBus windows are initialized in a way
that is identical to what all other DMA-capable drivers for Marvell
EBU platforms do.

Commit ba0d7ed391b7b "ARM: dts: enable ahci sata and sata phy for
exynos5250" added a new binding document for the sata phy device,
and changed the sata controller binding. However, in both cases
significant aspects of the binding remained undocumented.
This attempts to reconstruct the actual binding from the usage.

dm-era is a target that behaves similar to the linear target. In
addition it keeps track of which blocks were written within a user
defined period of time called an 'era'. Each era target instance
maintains the current era as a monotonically increasing 32-bit
counter.
Use cases include tracking changed blocks for backup software, and
partially invalidating the contents of a cache to restore cache
coherency after rolling back a vendor snapshot.
dm-era is primarily expected to be paired with the dm-cache target.

The KVM API documentation is not clear about the semantics of the data
field on the mmio struct on the kvm_run struct.
This has become problematic when supporting ARM guests on big-endian
host systems with guests of both endianness types, because it is unclear
how the data should be exported to user space.
This should not break with existing implementations as all supported
existing implementations of known user space applications (QEMU and
kvmtools for virtio) only support default endianness of the
architectures on the host side.

The previous commit "ACPICA: Add auto-serialization support for ill-behaved
control methods" introduced the auto-serialization facility as a workaround
that can be enabled by "acpi_auto_serialize":
This feature marks control methods that create named objects as "serialized"
to avoid unwanted AE_ALREADY_EXISTS control method evaluation failures.
Enable method auto-serialization as the default kernel behavior. The new kernel
parameter is also changed from "acpi_auto_serialize" to "acpi_no_auto_serialize"
to reflect the default behavior.

This change adds support to automatically mark a control method as
"serialized" if the method creates any named objects. This will
positively prevent the method from being entered by more than one
thread and thus preventing a possible abort when an attempt is
made to create an object twice.
Implemented by parsing all non-serialize control methods at table
load time.
This feature is disabled by default and this patch also adds a new
Linux kernel parameter "acpi_auto_serialize" to allow this feature
to be turned on for a specific boot.

According to the reports, the "acpi_serialize" mechanism is broken as:
A. The parallel method calls can still happen when the interpreter lock is
released under the following conditions:
1. External callbacks are invoked, for example, by the region handlers,
the exception handlers, etc.;
2. Module level execution is performed when Load/LoadTable opcodes are
executed, and
3. The _REG control methods are invoked to complete the region
registrations.
B. For the following situations, the interpreter lock need to be released
even for a serialized method while currently, the lock-releasing
operation is marked as a no-op by
acpi_ex_relinquish/reacquire_interpreter() when this mechanism is
enabled:
1. Wait opcode is executed,
2. Acquire opcode is executed, and
3. Sleep opcode is executed.
This patch removes this mechanism and the internal
acpi_ex_relinquish/reacquire_interpreter() APIs. Lv Zheng.

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.
