Linux 3.17-rc1

More ACPI and power management updates for 3.17-rc1

 - Fix for an ACPI-based device hotplug regression introduced in 3.14
   that causes a kernel panic to trigger when memory hot-remove is
   attempted with CONFIG_ACPI_HOTPLUG_MEMORY unset from Tang Chen.

 - Fix for a cpufreq regression introduced in 3.16 that triggers a
   "sleeping function called from invalid context" bug in
   dev_pm_opp_init_cpufreq_table() from Stephen Boyd.

 - ACPI battery driver fix for a warning message added in 3.16 that
   prints silly stuff sometimes from Mariusz Ceier.

 - Hibernation fix for safer handling of mismatches in the 820 memory
   map between the configurations during image creation and during
   the subsequent restore from Chun-Yi Lee.

 - ACPI processor driver fix to handle CPU hotplug notifications
   correctly during system suspend/resume from Lan Tianyu.

 - Series of four cpuidle menu governor cleanups that also should
   speed it up a bit from Mel Gorman.

 - Fixes for the speedstep-smi, integrator, cpu0 and arm_big_little
   cpufreq drivers from Hans Wennborg, Himangi Saraogi, Markus Pargmann
   and Uwe Kleine-König.

 - Version 3.0 of the analyze_suspend.py suspend profiling tool
   from Todd E Brandt.

This is the bulk of GPIO changes for the v3.17 development
cycle, and this time we got a lot of action going on and
it will continue:

- The core GPIO library implementation has been split up in
  three different files:
  - gpiolib.c for the latest and greatest and shiny GPIO
    library code using GPIO descriptors only
  - gpiolib-legacy.c for the old integer number space API
    that we are phasing out gradually
  - gpiolib-sysfs.c for the sysfs interface that we are
    not entirely happy with, but has to live on for
    ABI compatibility

- Add a flags argument to *gpiod_get* functions, with some
  backward-compatibility macros to ease transitions. We
  should have had the flags there from the beginning it
  seems, now we need to clean up the mess. There is a plan
  on how to move forward here devised by Alexandre Courbot
  and Mark Brown.

- Split off a special <linux/gpio/machine.h> header for the
  board gpio table registration, as per example from the
  regulator subsystem.

- Start to kill off the return value from gpiochip_remove()
  by removing the __must_check attribute and removing all
  checks inside the drivers/gpio directory. The rationale
  is: well what were we supposed to do if there is an error
  code? Not much: print an error message. And gpiolib already
  does that. So make this function return void eventually.

- Some cleanups of hairy gpiolib code, make some functions
  not to be used outside the library private and make sure
  they are not exported, remove gpiod_lock/unlock_as_irq()
  as the existing function is for driver-internal use and
  fine as it is, delete gpio_ensure_requested() as it is
  not meaningful anymore.

- Support the GPIOF_ACTIVE_LOW flag from gpio_request_one()
  function calls, which is logical since this is already
  supported when referencing GPIOs from e.g. device trees.

- Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use
  the gpiolib irqchip helpers cutting down on GPIO irqchip
  boilerplate a bit more.

- New driver for the Zynq GPIO block.

- The usual incremental improvements around a bunch of
  drivers.

- Janitorial syntactic and semantic cleanups by Jingoo Han,
  and Rickard Strandqvist especially.

ACPI and power management updates for 3.17-rc1

 - ACPICA update to upstream version 20140724.  That includes
   ACPI 5.1 material (support for the _CCA and _DSD predefined names,
   changes related to the DMAR and PCCT tables and ARM support among
   other things) and cleanups related to using ACPICA's header files.
   A major part of it is related to acpidump and the core code used
   by that utility.  Changes from Bob Moore, David E Box, Lv Zheng,
   Sascha Wildner, Tomasz Nowicki, Hanjun Guo.

 - Radix trees for memory bitmaps used by the hibernation core from
   Joerg Roedel.

 - Support for waking up the system from suspend-to-idle (also known
   as the "freeze" sleep state) using ACPI-based PCI wakeup signaling
   (Rafael J Wysocki).

 - Fixes for issues related to ACPI button events (Rafael J Wysocki).

 - New device ID for an ACPI-enumerated device included into the
   Wildcat Point PCH from Jie Yang.

 - ACPI video updates related to backlight handling from Hans de Goede
   and Linus Torvalds.

 - Preliminary changes needed to support ACPI on ARM from Hanjun Guo
   and Graeme Gregory.

 - ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui.

 - Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros
   (Rafael J Wysocki).

 - ACPI-based device hotplug cleanups from Wei Yongjun and
   Rafael J Wysocki.

 - Cleanups and improvements related to system suspend from
   Lan Tianyu, Randy Dunlap and Rafael J Wysocki.

 - ACPI battery cleanup from Wei Yongjun.

 - cpufreq core fixes from Viresh Kumar.

 - Elimination of a deadband effect from the cpufreq ondemand
   governor and intel_pstate driver cleanups from Stratos Karafotis.

   Mikulas Patocka.

 - Fix for the imx6 cpufreq driver from Anson Huang.

 - cpuidle core and governor cleanups from Daniel Lezcano,
   Sandeep Tripathy and Mohammad Merajul Islam Molla.

 - Build fix for the big_little cpuidle driver from Sachin Kamat.

 - Configuration fix for the Operation Performance Points (OPP)
   framework from Mark Brown.

 - APM cleanup from Jean Delvare.

   Andrey Utkin, Himangi Saraogi, Rickard Strandqvist, Thomas Renninger.

This is the 3.2.62 stable release

Here are the PPC and ARM changes for KVM, which I separated because
they had small conflicts (respectively within KVM documentation,
and with 3.16-rc changes).  Since they were all within the subsystem,
I took care of them.

Stephen Rothwell reported some snags in PPC builds, but they are all
fixed now; the latest linux-next report was clean.

New features for ARM include:
- KVM VGIC v2 emulation on GICv3 hardware
- Big-Endian support for arm/arm64 (guest and host)
- Debug Architecture support for arm64 (arm32 is on Christoffer's todo list)

And for PPC:
- Book3S: Good number of LE host fixes, enable HV on LE
- Book3S HV: Add in-guest debug support

This release drops support for KVM on the PPC440.  As a result, the
PPC merge removes more lines than it adds. :)

I also included an x86 change, since Davidlohr tied it to an independent
bug report and the reporter quickly provided a Tested-by; there was no
reason to wait for -rc2.
