@ -91,24 +91,6 @@ config ACPI_EC_DEBUGFS
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
bool "Deprecated /proc/acpi/event support"
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).
config ACPI_AC
