Pull ARM SoC fixes from Olof Johansson:
 "Another week, another small batch of fixes.

  Most of these make zynq, socfpga and sunxi platforms work a bit
  better:

   - due to new requirements for regulators, DWMMC on socfpga broke past
     v3.17
   - SMP spinup fix for socfpga
   - a few DT fixes for zynq
   - another option (FIXED_REGULATOR) for sunxi is needed that used to
     be selected by other options but no longer is.
   - a couple of small DT fixes for at91
   - ...and a couple for i.MX"

Pull ACPI and power management updates from Rafael Wysocki:
 "This is material that didn't make it to my 3.18-rc1 pull request for
  various reasons, mostly related to timing and travel (LinuxCon EU /
  LPC) plus a couple of fixes for recent bugs.

  The only really new thing here is the PM QoS class for memory
  bandwidth, but it is simple enough and users of it will be added in
  the next cycle.  One major change in behavior is that platform devices
  enumerated by ACPI will use 32-bit DMA mask by default.  Also included
  is an ACPICA update to a new upstream release, but that's mostly
  cleanups, changes in tools and similar.  The rest is fixes and
  cleanups mostly.

  Specifics:

   - Fix for a recent PCI power management change that overlooked the
     fact that some IRQ chips might not be able to configure PCIe PME
     for system wakeup from Lucas Stach.

   - Fix for a bug introduced in 3.17 where acpi_device_wakeup() is
     called with a wrong ordering of arguments from Zhang Rui.

   - A bunch of intel_pstate driver fixes (all -stable candidates) from
     Dirk Brandewie, Gabriele Mazzotta and Pali Rohár.

   - Fixes for a rather long-standing problem with the OOM killer and
     the freezer that frozen processes killed by the OOM do not actually
     release any memory until they are thawed, so OOM-killing them is
     rather pointless, with a couple of cleanups on top (Michal Hocko,
     Cong Wang, Rafael J Wysocki).

   - ACPICA update to upstream release 20140926, inlcuding mostly
     cleanups reducing differences between the upstream ACPICA and the
     kernel code, tools changes (acpidump, acpiexec) and support for the
     _DDN object (Bob Moore, Lv Zheng).

   - New PM QoS class for memory bandwidth from Tomeu Vizoso.

   - Default 32-bit DMA mask for platform devices enumerated by ACPI
     (this change is mostly needed for some drivers development in
     progress targeted at 3.19) from Heikki Krogerus.

   - ACPI EC driver cleanups, mostly related to debugging, from Lv
     Zheng.

   - cpufreq-dt driver updates from Thomas Petazzoni.

   - powernv cpuidle driver update from Preeti U Murthy"

Pull thermal management updates from Zhang Rui:
 "Sorry that I missed the merge window as there is a bug found in the
  last minute, and I have to fix it and wait for the code to be tested
  in linux-next tree for a few days.  Now the buggy patch has been
  dropped entirely from my next branch.  Thus I hope those changes can
  still be merged in 3.18-rc2 as most of them are platform thermal
  driver changes.

  Specifics:

   - introduce ACPI INT340X thermal drivers.

     Newer laptops and tablets may have thermal sensors and other
     devices with thermal control capabilities that are exposed for the
     OS to use via the ACPI INT340x device objects.  Several drivers are
     introduced to expose the temperature information and cooling
     ability from these objects to user-space via the normal thermal
     framework.

     From: Lu Aaron, Lan Tianyu, Jacob Pan and Zhang Rui.

   - introduce a new thermal governor, which just uses a hysteresis to
     switch abruptly on/off a cooling device.  This governor can be used
     to control certain fan devices that can not be throttled but just
     switched on or off.  From: Peter Feuerer.

   - introduce support for some new thermal interrupt functions on
     i.MX6SX, in IMX thermal driver.  From: Anson, Huang.

   - introduce tracing support on thermal framework.  From: Punit
     Agrawal.

   - small fixes in OF thermal and thermal step_wise governor"
