This is a note to let you know that I've just added the patch titled MIPS: Don't register r4k sched clock when CPUFREQ enabled to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: mips-don-t-register-r4k-sched-clock-when-cpufreq-enabled.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 07d69579e7fec27e371296d8ca9d6076fc401b5c Mon Sep 17 00:00:00 2001 From: Huacai Chen <chenhc@xxxxxxxxxx> Date: Fri, 22 Jul 2016 11:46:31 +0800 Subject: MIPS: Don't register r4k sched clock when CPUFREQ enabled From: Huacai Chen <chenhc@xxxxxxxxxx> commit 07d69579e7fec27e371296d8ca9d6076fc401b5c upstream. Don't register r4k sched clock when CPUFREQ enabled because sched clock need a constant frequency. Signed-off-by: Huacai Chen <chenhc@xxxxxxxxxx> Cc: John Crispin <john@xxxxxxxxxxx> Cc: Steven J .
