Hi,
I'm upgrading from v4.7 to v4.8 on MIPS/loongson2_cpufreq with
cpufreq/ondemand and I noticed that /proc/cpuinfo is always reporting
(regardless of system load):
BogoMIPS : 697150.20
and sysfs:
/sys/devices/system/cpu/cpufreq/policy0/affected_cpus:0
/sys/devices/system/cpu/cpufreq/policy0/cpuinfo_cur_freq:797800
