-What:	CONFIG_ACPI_PROCFS_POWER
-When:	2.6.39
-Why:	sysfs I/F for ACPI power devices, including AC and Battery,
-        has been working in upstream kernel since 2.6.24, Sep 2007.
-	In 2.6.37, we make the sysfs I/F always built in and this option

-	Remove this option and the ACPI power procfs interface in 2.6.39.
