3.16.7-ckt1 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Aaro Koskinen <aaro.koskinen@xxxxxx> commit aa08ed55442ac6f9810c055e1474be34e785e556 upstream. During 3.16 merge window, parts of the commit 8e8acb32960f (MIPS/loongson2_cpufreq: Fix CPU clock rate setting) seem to have been deleted probably due to a mismerge, and as a result cpufreq is broken again on Loongson2 boards in 3.16 and newer kernels. Fix by repeating the fix. Signed-off-by: Aaro Koskinen <aaro.koskinen@xxxxxx> Cc: Rafael J.
