-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.
-Who:	Rene Herman <rene.herman@gmail.com>

 What:	Code that is now under CONFIG_WIRELESS_EXT_SYSFS
 	(in net/core/net-sysfs.c)
 When:	After the only user (hal) has seen a release with the patches
