 Why:    Implementation became generic; users should now include
        linux/semaphore.h instead.
 Who:    Matthew Wilcox <willy@linux.intel.com>
+---------------------------
+What:   CONFIG_THERMAL_HWMON
+When:   January 2009
+Why:    This option was introduced just to allow older lm-sensors userspace
+        to keep working over the upgrade to 2.6.26. At the scheduled time of
+        removal fixed lm-sensors (2.x or 3.x) should be readily available.
