As we start to decomission the return value from gpiochip_remove()
the compilers emit warnings due to the function being tagged
__must_check. So drop this until we remove the return value
altogether.

Adds regulator support in PHY core. PHY core is modified to support
representation of multi-phy PHY providers with each individual PHY
as sub-node OF PHY provider node. New PHY drivers adapted to PHY
framework (hix5hd2 SATA PHY, QCOM APQ8064 SATA PHY,
QCOM IPQ806x SATA PHY, Berlin SATA PHY and MiPHY356x). Existing
TI PIPE3 PHY can now be used for PCIe too. Includes misc fixes and

Since ACPI wakeup GPEs are going to be enabled during system suspend
as well as for runtime wakeup by a subsequent patch and the same
notify handlers will be used in both cases, rework the ACPI device
wakeup notification framework so that the part specific to physical
devices is always run asynchronously from the PM workqueue. This
prevents runtime resume callbacks for those devices from being
run during system suspend and resume which may not be appropriate,
among other things.
Also make ACPI device wakeup notification handling a bit more robust
agaist subsequent removal of ACPI device objects, whould that ever
happen, and create a wakeup source object for each ACPI device
configured for wakeup so that wakeup notifications for those
devices can wake up the system from the "freeze" sleep state.

Add driver for STMicroelectronics ST21NFCB NFC controller.
ST21NFCB is using NCI protocol and a proprietary low level transport
protocol called NDLC used on top.
NDLC:
The protocol defines 2 types of frame:
- One type carrying NCI data (referred as DATAFRAME frames).
- One type carrying protocol information used for flow control and error
control mechanisms (referred as SUPERVISOR frames).
After each frame transmission to the NFC controller, the device host
SHALL waitfor an ACK (SUPERVISOR frame) reception before sending a
new frame.
The NFC controller MAY send a frame at anytime to the device host.
The NFC controller MAY send a specific WAIT supervisor frame to indicate
to device host that a NCI data packet has been received but that it could
take significant time before the NFC controller sends an ACK and thus
allows next data reception.

Currently APEI depends on x86 architecture. It is because of NMI hardware
error notification of GHES which is currently supported by x86 only.
However, many other APEI features can be still used perfectly by other
architectures.
This commit adds two symbols:
1. HAVE_ACPI_APEI for those archs which support APEI.
2. HAVE_ACPI_APEI_NMI which is used for NMI code isolation in ghes.c
file. NMI related data and functions are grouped so they can be wrapped
inside one #ifdef section. Appropriate function stubs are provided for
!NMI case.
Note there is no functional changes for x86 due to hard selected
HAVE_ACPI_APEI and HAVE_ACPI_APEI_NMI symbols.

Here's a set of changes that implement a PE file signature checker.
This provides the following facility:
(1) Extract the signature from the PE file. This is a PKCS#7 message
containing, as its data, a hash of the signed parts of the file.
(2) Digest the signed parts of the file.
(3) Compare the digest with the one from the PKCS#7 message.
(4) Validate the signatures on the PKCS#7 message and indicate
whether it was matched by a trusted key.

Here's a set of changes that implement a PKCS#7 message parser in the kernel.
The PKCS#7 message parsing will then be used to limit kexec to authenticated
kernels only if so configured.
The changes provide the following facilities:
(1) Parse an ASN.1 PKCS#7 message and pick out useful bits such as the data
content and the X.509 certificates used to sign it and all the data
signatures.
(2) Verify all the data signatures against the set of X.509 certificates
available in the message.
(3) Follow the certificate chains and verify that:
(a) for every self-signed X.509 certificate, check that it validly signed
itself, and:
(b) for every non-self-signed certificate, if we have a 'parent'
certificate, the former is validly signed by the latter.
(4) Look for intersections between the certificate chains and the trusted
keyring, if any intersections are found, verify that the trusted
certificates signed the intersection point in the chain.
(5) For testing purposes, a key type can be made available that will take a
PKCS#7 message, check that the message is trustworthy, and if so, add its
data content into the key.
Note that (5) has to be altered to take account of the preparsing patches
already committed to this branch.

we have currently 2 DMA drivers that try to co-exist.
drivers/dma/omap-dma.c which registers it's own IRQ and is device tree
aware and uses arch/arm/plat-omap/dma.c instance created by
arch/arm/mach-omap2/dma.c to maintain channel usage (omap_request_dma).
Currently both try to register interrupts and mach-omap2/plat-omap dma.c
attempts to use the IRQ number registered by hwmod to register it's own
interrupt handler.
Now, there is no reasonable way of static allocating DMA irq in GIC
SPI when we use crossbar. However, since the dma_chan structure is
freed as a result of IRQ not being present due to devm allocation,
maintaining information of channel by platform code fails at a later
point in time when that region of memory is reused.
So, if hwmod does not indicate an IRQ number, then, assume that
dma-engine will take care of the interrupt handling.

netdev_name() returns dev->name only when the net_device is in
NETREG_REGISTERED state.
However, dev->name is always populated on creation, so we can easily use

There are two cases when there's no real name - when it's an empty string
or when the name is in form of "eth%d", then netdev_name() returns "unnamed

Merge "ARM: tegra: move fuse code out of arch/arm" from Thierry Reding:
This branch moves code related to the Tegra fuses out of arch/arm and
into a centralized location which could be shared with ARM64. It also
adds support for reading the fuse data through sysfs.
Included is also some preparatory work that moves Tegra-related header
files from include/linux to include/soc/tegra as suggested by Arnd.
Furthermore the Tegra chip ID is now retrieved using a function rather
than a variable so that sanity checks can be done. This is convenient
in subsequent patches that will move some of the code that's currently
called from Tegra machine setup into regular initcalls so that it can
be reused on 64-bit ARM. The sanity checks help with verifying that no
code tries to obtain the Tegra chip ID before the underlying driver is
properly initialized.

- A rather large and intrusive bundle of fixes to address serious
performance regressions introduced by the new rwsem / mcs
technology. Simpler solutions have been discussed, but they would
have been ugly bandaids with more risk than doing the right thing.
- Make the rwsem spin on owner technology opt-in for architectures
and enable it only on the known to work ones.
- A few fixes to the lockdep userspace library"
* 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
locking/rwsem: Add CONFIG_RWSEM_SPIN_ON_OWNER
locking/mutex: Disable optimistic spinning on some architectures

Pull RCU fixes from Thomas Gleixner:
"Two RCU patches:
- Address a serious performance regression on open/close caused by
commit ac1bea85781e ("Make cond_resched() report RCU quiescent
states")
- Export RCU debug functions. Not a regression, but enablement to
address a serious recursion bug in the sl*b allocators in 3.17"
* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
rcu: Reduce overhead of cond_resched() checks for RCU
rcu: Export debug_init_rcu_head() and and debug_init_rcu_head()

Pull ACPI and power management fixes from Rafael Wysocki:
"These are a few recent regression fixes, a revert of the ACPI video
commit I promised, a system resume fix related to request_firmware(),
an ACPI video quirk for one more Win8-oriented BIOS, an ACPI device
enumeration documentation update and a few fixes for ARM cpufreq
drivers.
Specifics:
- Fix for a recently introduced NULL pointer dereference in the core
system suspend code occuring when platforms without ACPI attempt to
use the "freeze" sleep state from Zhang Rui.
- Fix for a recently introduced build warning in cpufreq headers from
Brian W Hart.
- Fix for a 3.13 cpufreq regression related to sysem resume that
triggers on some systems with multiple CPU clusters from Viresh
Kumar.
- Fix for a 3.4 regression in request_firmware() resulting in
WARN_ON()s on some systems during system resume from Takashi Iwai.
- Revert of the ACPI video commit that changed the default value of
the video.brightness_switch_enabled command line argument to 0 as
it has been reported to break existing setups.
- ACPI device enumeration documentation update to take recent code
changes into account and make the documentation match the code
again from Darren Hart.
- Fixes for the sa1110, imx6q, kirkwood, and cpu0 cpufreq drivers
from Linus Walleij, Nicolas Del Piano, Quentin Armitage, Viresh
Kumar.
- New ACPI video blacklist entry for HP ProBook 4540s from Hans de
Goede"
