Title:
  armhf: cpufreq doesn't autoload by default

Status in linux package in Ubuntu:
  New

Bug description:
  While cpufreq support on armhf is available for a while, if support is
  compiled as a kernel module, the corresponding module doesn't autoload
  by default, and thus frequency scaling is not active upon boot until a
  user manually load it (or until /etc/modules is modified to forcibly
  load it).

  While in Trusty cpufreq was built-in on armhf, starting with Utopic we
  made support available as a kernel module, making people think that
  cpufreq was either broken or missing in their new kernels.

  To fix it, revert back that decision and make cpufreq compiled-in
  again on armhf - it affects Utopic and Vivid kernels.
