-What:	ACPI procfs interface
-When:	July 2007
-Why:	After ACPI sysfs conversion, ACPI attributes will be duplicated
-	in sysfs and the ACPI procfs interface should be removed.

 What:	/proc/acpi/button

-	  The Procfs interface for ACPI is made optional for backward compatibility.
-	  As the same functions are duplicated in the sysfs interface
-	  and this proc interface will be removed some time later,
