From 62663ea8220366472fe20462831f2d69d7987439 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Tue, 3 Feb 2009 17:46:46 +0100 Subject: ACPI: cpufreq: Remove deprecated /proc/acpi/processor/../performance proc entries They were long enough set deprecated... Update Documentation/cpu-freq/users-guide.txt: The deprecated files listed there seen not to exist for some time anymore already.
