From 47f5c892b06797336a34f1096b4b617623aa1960 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Thu, 15 Jul 2010 10:46:33 +0800 Subject: ACPI: remove deprecated ACPI procfs I/F Rmove deprecated ACPI procfs I/F, including /proc/acpi/debug_layer /proc/acpi/debug_level /proc/acpi/info /proc/acpi/dsdt /proc/acpi/fadt /proc/acpi/sleep because the sysfs I/F is already available and has been working well for years.
