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.
