Merge tag 'pm+acpi-3.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management fixes from Rafael Wysocki:
1) Four fixes for cpufreq regressions introduced by the changes that
removed Device Tree parsing for CPU device nodes from cpufreq
drivers from Sudeep KarkadaNagesha.
2) Two fixes for recent cpufreq regressions introduced by changes
related to the preservation of sysfs attributes over system
suspend/resume cycles from Viresh Kumar.
3) Fix for ACPI-based wakeup signaling in the PCI subsystem that
fails to stop PME polling for devices put into the D3cold power
state from Rafael J Wysocki.
4) Fix for bad interactions between cpufreq and udev on systems
supporting intel_pstate where acpi-cpufreq is available as well
from Yinghai Lu.
* tag 'pm+acpi-3.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpufreq: return EEXIST instead of EBUSY for second registering
PCI / ACPI / PM: Clear pme_poll for devices in D3cold on wakeup
ARM: shmobile: change dev_id to cpu0 while registering cpu clock
ARM: i.MX: change dev_id to cpu0 while registering cpu clock
cpufreq: imx6q-cpufreq: assign cpu_dev correctly to cpu0 device
cpufreq: cpufreq-cpu0: assign cpu_dev correctly to cpu0 device
cpufreq: unlock correct rwsem while updating policy->cpu
cpufreq: Clear policy->cpus bits in __cpufreq_remove_dev_finish()
