 - Fix for a recent cpufreq regression related to acpi-cpufreq and
   suspend/resume from Viresh Kumar.

 - cpufreq stats reference counting fix from Viresh Kumar.

 - intel_pstate driver fixes from Dirk Brandewie and Konrad Rzeszutek
   Wilk.

 - New ACPI suspend blacklist entry for Sony Vaio VGN-FW21M from Fabio
   Valentini.

 - ACPI Platform Error Interface (APEI) fix from Chen Gong.

 - PCI root bridge hotplug locking fix from Yinghai Lu.

* tag 'pm+acpi-3.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  PCI / ACPI: hold acpi_scan_lock during root bus hotplug
  ACPI / APEI: fix error status check condition for CPER
  ACPI / PM: fix suspend and resume on Sony Vaio VGN-FW21M
  cpufreq: acpi-cpufreq: Don't set policy->related_cpus from .init()
  cpufreq: stats: do cpufreq_cpu_put() corresponding to cpufreq_cpu_get()
  intel-pstate: Use #defines instead of hard-coded values.
  cpufreq / intel_pstate: Fix calculation of current frequency
  cpufreq / intel_pstate: Add function to check that all MSRs are valid
