them. Prepare for removing /proc/acpi

Say N to delete /proc/acpi/ files that have moved to /sys/
config ACPI_PROCFS_POWER
bool "Deprecated power /proc/acpi directories"
depends on PROC_FS
help
For backwards compatibility, this option allows
deprecated power /proc/acpi/ directories to exist, even when
they have been replaced by functions in /sys.
The deprecated directories (and their replacements) include:
/proc/acpi/battery/* (/sys/class/power_supply/*)
/proc/acpi/ac_adapter/* (sys/class/power_supply/*)
This option has no effect on /proc/acpi/ directories
and functions, which do not yet exist in /sys
This option, together with the proc directories, will be
deleted in 2.6.39.
