 - Fix for an error code path memory leak in pm_genpd_attach_cpuidle()
   from Jonghwan Choi.

 - Fix for smp_processor_id() usage in preemptible code in powernow-k8
   from Andreas Herrmann.

 - Fix for a suspend-related memory leak in cpufreq stats from Xiaobing
   Tu.

 - Freezer fix for failure to clear PF_NOFREEZE along with PF_KTHREAD in
   flush_old_exec() from Oleg Nesterov.

 - acpi_processor_notify() fix from Alan Cox.
