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.
