ACPI and power management fixes and new device IDs for 3.13-rc7

- VGA switcheroo was broken for some users as a result of the ACPI-based
  PCI hotplug (ACPIPHP) changes in 3.12, because some previously ignored
  hotplug events started to be handled.  The fix causes them to be
  ignored again.

- There are two more issues related to cpufreq's suspend/resume handling
  changes from the 3.12 cycle addressed by Viresh Kumar's fixes.

- intel_pstate triggers a divide error in a timer function if the P-state
  information it needs is missing during initialization.  This leads to
  kernel panics on nested KVM clients and is fixed by failing the
  initialization cleanly in those cases.

- PCI initalization code changes during the 3.9 cycle uncovered BIOS
  issues related to ACPI wakeup notifications (some BIOSes send them
  for devices that aren't supposed to support ACPI wakeup).  Work around
  them by installing an ACPI wakeup notify handler for all PCI devices
  with ACPI support.

- The Calxeda cpuilde driver's probe function is tagged as __init, which
  is incorrect and causes a section mismatch to occur during build.  Fix
  from Andre Przywara removes the __init tag from there.

- During the 3.12 cycle ACPIPHP started to print warnings about missing
  _ADR for devices that legitimately don't have it.  Fix from Toshi Kani
  makes it only print the warnings where they make sense.

Linux 3.13-rc6

ACPI and power management fixes and new device IDs for 3.13-rc6

- Fix for a cpufreq regression causing stale sysfs files to be left
  behind during system resume if cpufreq_add_dev() fails for one or
  more CPUs from Viresh Kumar.

- Fix for a bug in cpufreq causing CONFIG_CPU_FREQ_DEFAULT_* to be
  ignored when the intel_pstate driver is used from Jason Baron.

- System suspend fix for a memory leak in pm_vt_switch_unregister()
  that forgot to release objects after removing them from
  pm_vt_switch_list.  From Masami Ichikawa.

- Intel Valley View device ID and energy unit encoding update for the
  (recently added) Intel RAPL (Running Average Power Limit) driver
  from Jacob Pan.

- Intel Bay Trail SoC GPIO and ACPI device IDs for the Low Power
  Subsystem (LPSS) ACPI driver from Paul Drews.

Linux 3.13-rc5

drm/tegra: Changes for v3.14-rc1

This series of changes brings DRM panel support as well as initial code
to register DSI hosts and peripherals and bind them to DSI drivers. The
panel and DSI code are both used by the simple panel driver.

The Tegra-specific changes build on top of this work to add support for
various panels found on Tegra boards. New drivers enable the DSI host
found on Tegra114 and a special hardware block that calibrates the pads
used for DSI and CSI. The host1x and the display controller drivers gain
basic Tegra124 support. To round of the new features, the DRM driver now
sports a very simple PRIME implementation.

In addition there are various improvements such as the host1x API being
exported so that client drivers (like the Tegra DRM driver) can be built
as modules. HDMI now does better power management and legacy FBDEV can
now be disabled via Kconfig (though it's still enabled by default). A
few sparse warnings have been squashed and various parts of the code
have become more robust.

Post-3.13-rc3 power management fixup

This reverts two cpufreq commits that fixed issues for some people,
but broke things for others, so revert them and we'll need to fix the
original problems differently.

Linux 3.13-rc3

Power management fixes for 3.13-rc3

 - cpufreq regression fix from Bjørn Mork restoring the pre-3.12
   behavior of the framework during system suspend/hibernation to
   avoid garbage sysfs files from being left behind in case of a
   suspend error.

 - PNP regression fix to restore the correct states of devices after
   resume from hibernation broken in 3.12.  From Dmitry Torokhov.

 - cpuidle fix to prevent cpuidle device unregistration from crashing
   due to a NULL pointer dereference if cpuidle has been disabled
   from the kernel command line.  From Konrad Rzeszutek Wilk.

 - intel_idle fix for the C6 state definition on Intel Avoton/Rangeley
   processors from Arne Bockholdt.

 - Power capping framework fix to make the energy_uj sysfs attribute
   work in accordance with the documentation.  From Srinivas Pandruvada.

 - epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has
   been compiled with CONFIG_PM_SLEEP unset (in which case that flag
   should not have any effect).  From Amit Pundir.

 - cpufreq fix to prevent governor sysfs files from being lost over
   system suspend/resume in some (arguably unusual) situations.  From
   Viresh Kumar.
