  Log:
  MPSAFE locking
  
  * Restructure the event handling path.  acpi_tz_thread() now calls
    acpi_tz_timeout() any time an event occurs.  acpi_tz_timeout() checks
    the flags and calls acpi_tz_power_profile(), acpi_tz_establish(), and
    acpi_tz_monitor() as appropriate.  Notifies only do a wakeup and let
    acpi_tz_thread() do the actual work.  This path is cleaner and allows
    locking since the call path is now always a D.A.G.
  * Add the acpi_tz_signal() function to set flags and wake the thread.
  * Remove the tz_tmp_updating flag since calls are serialized by
    acpi_tz_thread().
  * Remove Giant locking.
