Fixes these warnings:

These cause errors in the generated html output, like below, so drop

Johannes Berg eda603f6cd docbook: warn on unused doc entries
When you don't use !E or !I but only !F, then it's very easy to miss
including some functions, structs etc.  in documentation.  To help
finding which ones were missed, allow printing out the unused ones as
warnings.

For example, using this on mac80211 yields a lot of warnings like this:

  Warning: didn't use docs for DOC: mac80211 workqueue
  Warning: didn't use docs for ieee80211_max_queues
  Warning: didn't use docs for ieee80211_bss_change
  Warning: didn't use docs for ieee80211_bss_conf

when generating the documentation for it.

Rafael J. Wysocki 28eb5f274a PCI: PCIe: Ask BIOS for control of all native services at once
After commit 852972acff (ACPI: Disable
ASPM if the platform won't provide _OSC control for PCIe) control of
the PCIe Capability Structure is unconditionally requested by
acpi_pci_root_add(), which in principle may cause problems to
happen in two ways.  First, the BIOS may refuse to give control of
the PCIe Capability Structure if it is not asked for any of the
_OSC features depending on it at the same time.  Second, the BIOS may
assume that control of the _OSC features depending on the PCIe
Capability Structure will be requested in the future and may behave
incorrectly if that doesn't happen.  For this reason, control of
the PCIe Capability Structure should always be requested along with
control of any other _OSC features that may depend on it (ie. PCIe
native PME, PCIe native hot-plug, PCIe AER).

Rework the PCIe port driver so that (1) it checks which native PCIe
port services can be enabled, according to the BIOS, and (2) it
requests control of all these services simultaneously.  In
particular, this causes pcie_portdrv_probe() to fail if the BIOS
refuses to grant control of the PCIe Capability Structure, which
means that no native PCIe port services can be enabled for the PCIe
Root Complex the given port belongs to.  If that happens, ASPM is
disabled to avoid problems with mishandling it by the part of the
PCIe hierarchy for which control of the PCIe Capability Structure
has not been received.

Make it possible to override this behavior using 'pcie_ports=native'
(use the PCIe native services regardless of the BIOS response to the
control request), or 'pcie_ports=compat' (do not use the PCIe native
services at all).

Accordingly, rework the existing PCIe port service drivers so that
they don't request control of the services directly.

Ian Campbell 1dc7ce99b0 xen: pvhvm: rename xen_emul_unplug=ignore to =unnnecessary
It is not immediately clear what this option causes to become
ignored. The actual meaning is that it is not necessary to unplug the
emulated devices to safely use the PV ones, even if the platform does
not support the unplug protocol. (pressumably the user will only add
this option if they have ensured that their domain configuration is
safe).

I think xen_emul_unplug=unnecessary better captures this.

Stefan Richter 1ee4168057 Documentation: kernel-locking: mutex_trylock cannot be used in interrupt context
Chapter 6 is right about mutex_trylock, but chapter 10 wasn't.  This error
was introduced during semaphore-to-mutex conversion of the Unreliable
guide.  :-)

If user context which performs mutex_lock() or mutex_trylock() is
preempted by interrupt context which performs mutex_trylock() on the same
mutex instance, a deadlock occurs.  This is because these functions do not
disable local IRQs when they operate on mutex->wait_lock.

Jean Delvare 008e5f3350 hwmon: (pc87427) Add temperature monitoring support
Add support for the 6 temperature monitoring channels of the PC87427.
Note that the sensors resolution can vary, and I couldn't find a way
to figure it out, so we might have to compensate in user-space.

Jean Delvare 328716bc16 hwmon: (pc87427) Add support for manual fan speed control
Add initial support for PWM outputs of the PC87427 Super-I/O chip.
Only mode change and manual fan speed control are supported. Automatic
mode configuration isn't supported, and won't be until at least one
board is known, which makes uses of the PWM outputs.

Steve Glendinning 9df7305b5a hwmon: Add driver for SMSC EMC2103 temperature monitor and fan controller

closed-loop control of one fan.  This patch adds support for
them.

Jean Delvare 5a9c2cd881 hwmon: Remove in[0-*]_fault from sysfs-interface
Fault files are for hardware failures that can be reported. So far
we've seen chips reporting such failures for temperature sensors and
fans, but not for voltages. Remove in[0-*]_fault for now. It can be
added back later if really needed, but I doubt it.

Add currX_alarm, currX_min_alarm, currX_max_alarm and currX_beep
attributes to the hwmon sysfs API.

currX_min_alarm and currX_max_alarm are already supported by the LTC4215
and LTC4245 drivers. currX_alarm is supported by the LTC4261 driver.

Ira W. Snyder 5950ec8d3e hwmon: (ltc4245) Expose all GPIO pins as analog voltages
Add support for exposing all GPIO pins as analog voltages. Though this is
not an ideal use of the chip, some hardware engineers may decide that the
LTC4245 meets their design requirements when studying the datasheet.

The GPIO pins are sampled in round-robin fashion, meaning that a slow
reader will see stale data. A userspace application can detect this,
because it will get -EAGAIN when reading from a sysfs file which contains
stale data.

Users can choose to use this feature on a per-chip basis by using either
platform data or the OF device tree (where applicable).

FUJITA Tomonori ce00f7feb0 Documentation: DMA-API-HOWTO.txt: rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN
ARCH_KMALLOC_MINALIGN was renamed to ARCH_DMA_MINALIGN (the commit
a6eb9fe105).

ARCH_DMA_MINALIGN must be defined instead of ARCH_KMALLOC_MINALIGN to
ensure that kmalloc'ed buffer is DMA-safe.
