  Log:
  MPSAFE locking
  
  * Serialize calls to acpi_alloc_resource(), acpi_release_resource(),
    acpi_Enable(), acpi_Disable(), and acpi_debug_sysctl().
  * Acquire the ACPI mutex in acpi_register_ioctl(), acpi_deregister_ioctl(),
    and acpiioctl().
  * Acquire the mutex while disabling subsequent requests to enter a
    sleep state in acpi_SetSleepState().
  * Be sure to re-enable sleep requests and don't run resume methods when
    the current request fails.
  * Don't check if sleep requests are disabled in the ACPIIO_SETSLPSTATE
    ioctl.  acpi_SetSleepState() does this for us.
  * Remove the acquisition of Giant from the struct cdevsw.
  * Remove the ACPI_USE_THREADS option.
