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" * tag 'pm+acpi-3.16-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpuidle: mvebu: Fix the name of the states cpufreq: unlock when failing cpufreq_update_policy() intel_pstate: Correct rounding in busy calculation ACPI: use kstrto*() instead of simple_strto*() ACPI / processor replace __attribute__((packed)) by __packed ACPI / battery: add quirk for Acer Aspire V5-573G ACPI / battery: use callback for setting up quirks ACPI / LPSS: Take I2C host controllers out of reset x86, kaslr: boot-time selectable with hibernation PM / hibernate: introduce "nohibernate" boot parameter cpufreq: cpufreq-cpu0: fix CPU_THERMAL dependency ACPI / ia64 / sba_iommu: Restore the working initialization ordering
