-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.

Create /proc/acpi/sleep
Deprecated by /sys/power/state
-config ACPI_PROCFS
- bool "Procfs interface (deprecated)"
- default y
- ---help---
- 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,
- it's marked as deprecated.
- ( /proc/acpi/debug_layer && debug_level are deprecated by
- /sys/module/acpi/parameters/debug_layer && debug_level.
- /proc/acpi/info is deprecated by
- /sys/module/acpi/parameters/acpica_version )
