I think this should be not removed now. Since there are still interfaces under /proc/acpi (E.G, /proc/acpi/wakeup and /proc/acpi/lid/*).
The origin commit which introduces the kconfig is to make some interfaces that have backup interfaces in the sysfs configurable before removing them actually.
So we still need this kconfig when try to remove remaining /proc/acpi interfaces.
commit b981c591891dc8885de36498d38fa8d8a5481069 Author: Zhang Rui <rui.zhang@intel.com> Date: Mon Jan 29 11:02:30 2007 +0800
ACPI: add a Kconfig option for ACPI procfs interface
Add a kconfig option CONFIG_ACPI_PROCFS to make procfs interface a configurable attribute of ACPI.
No procfs interface is actually deprecated, and no sysfs interface is added in this patch.
CONGI_ACPI_PROCFS is used to mark procfs interface as deprecated once the same function is duplicated in sysfs.
