 	  Thus this option is a debug option that helps to write ACPI drivers
 	  and can be used to identify ACPI code or EC firmware bugs.
 
-config ACPI_PROC_EVENT

-	depends on PROC_FS
-	default y
-	help
-	  A user-space daemon, acpid, typically reads /proc/acpi/event
-	  and handles all ACPI-generated events.
-
-	  These events are now delivered to user-space either
-	  via the input layer or as netlink events.
-
-	  This build option enables the old code for legacy
-	  user-space implementation.  After some time, this will
-	  be moved under CONFIG_ACPI_PROCFS, and then deleted.
-
-	  Say Y here to retain the old behaviour.  Say N if your
-	  user-space is newer than kernel 2.6.23 (September 2007).
