---help---
This option adds support for ACPI suspend states.
With this option, you will be able to put the system "to sleep".
Sleep states are low power states for the system and devices. All
of the system operating state is saved to either memory or disk
(depending on the state), to allow the system to resume operation
quickly at your request.
Although this option sounds really nifty, barely any of the device
drivers have been converted to the new driver model and hence few
have proper power management support.
This option is not recommended for anyone except those doing driver
power management development.

depends on PROC_FS
---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 )
For backwards compatibility, this option allows
depricated /proc/acpi/ files to exist, even when
they have been replaced by functions in /sys.
The deprecated files (and their replacements) include:
/proc/acpi/sleep (/sys/power/state)
/proc/acpi/info (/sys/modules/acpi/parameters/acpica_version)
/proc/acpi/dsdt (/sys/firmware/acpi/tables/DSDT)
/proc/acpi/fadt (/sys/firmware/acpi/tables/FACP)
/proc/acpi/debug_layer (/sys/module/acpi/parameters/debug_layer)
/proc/acpi/debug_level (/sys/module/acpi/parameters/debug_level)
This option has no effect on /proc/acpi/ files
and functions which do not yet exist in /sys.
Say N to delete /proc/acpi/ files that have moved to /sys/
