---------------------------
-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
See also Documentation/power/pm.txt, pci=noacpi
