Bug Description

After upgrading from 3.13 (trusty) to 3.16 (utopic) most cpufreq stuff have vanished.
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
performance powersave
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
intel_pstate
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
2600000
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
performance
$ sudo cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq
2291679
$ cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq
2600000
$

I suppose this is because of the transition to intel_pstate. However, the frequencies seem to be wrong. I'm pretty sure the max freq used to be less than 2000000, and when entering performance mode the cpu ran at something like 1,8 GHz.

However, both /proc/cpuinfo and /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq report something (wrong as it seems), but the cpufreq indicator always shows the cpu to run at lowest possible speed.
