Merge tag 'pm+acpi-3.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI and power management fixes from Rafael Wysocki:
 "These are fixes mostly (ia64 regression related to the ACPI
  enumeration of devices, cpufreq regressions, fix for I2C controllers
  included in Intel SoCs, mvebu cpuidle driver fix related to sysfs)
  plus additional kernel command line arguments from Kees to make it
  possible to build kernel images with hibernation and the kernel
  address space randomization included simultaneously, a new ACPI
  battery driver quirk for a system with a broken BIOS and a couple of
  ACPI core cleanups.

  Specifics:

   - Fix for an ia64 regression introduced during the 3.11 cycle by a
     commit that modified the hardware initialization ordering and made
     device discovery fail on some systems.

   - Fix for a build problem on systems where the cpufreq-cpu0 driver is
     built-in and the cpu-thermal driver is modular from Arnd Bergmann.

   - Fix for a recently introduced computational mistake in the
     intel_pstate driver that leads to excessive rounding errors from
     Doug Smythies.

   - Fix for a failure code path in cpufreq_update_policy() that fails
     to unlock the locks acquired previously from Aaron Plattner.

   - Fix for the cpuidle mvebu driver to use shorter state names which
     will prevent the sysfs interface from returning mangled strings.
     From Gregory Clement.

   - ACPI LPSS driver fix to make sure that the I2C controllers included
     in BayTrail SoCs are not held in the reset state while they are
     being probed from Mika Westerberg.

   - New kernel command line arguments making it possible to build
     kernel images with hibernation and kASLR included at the same time
     and to select which of them will be used via the command line (they
     are still functionally mutually exclusive, though).  From Kees
     Cook.

   - ACPI battery driver quirk for Acer Aspire V5-573G that fails to
     send battery status change notifications timely from Alexander
     Mezin.

   - Two ACPI core cleanups from Christoph Jaeger and Fabian Frederick"
