  ACPI: use for_each_possible_cpu() instead of for_each_cpu()
  ACPI: delete newly added debugging macros in processor_perflib.c
  ACPI: UP build fix for bugzilla-5737
  Enable P-state software coordination via _PDC
  P-state software coordination for speedstep-centrino
  P-state software coordination for acpi-cpufreq
  P-state software coordination for ACPI core
  ACPI: create acpi_thermal_resume()
  ACPI: create acpi_fan_suspend()/acpi_fan_resume()
  ACPI: pass pm_message_t from acpi_device_suspend() to root_suspend()
  ACPI: create acpi_device_suspend()/acpi_device_resume()
  ACPI: replace spin_lock_irq with mutex for ec poll mode
  ACPI: Allow a WAN module enable/disable on a Thinkpad X60.
  sem2mutex: acpi, acpi_link_lock
  ACPI: delete unused acpi_bus_drivers_lock
  sem2mutex: drivers/acpi/processor_perflib.c
  ACPI add ia64 exports to build acpi_memhotplug as a module
  ACPI: asus_acpi_init(): propagate correct return value
  ...
