Bug Description

Support for the Skylake H/S processors (0x5e) has been added to linux 4.3, but it would be nice if this could be backported to Wily as well. The upstream patch is https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/cpufreq/intel_pstate.c?id=1c9391238753ffb370f02743b5f43bac6dea304b.

It might also be a good idea to include https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/cpufreq/intel_pstate.c?id=ba88d4338f226766f510e207911dde8c1875e072 since that patch fixes enabling HWP for non-boot CPUs and Skylake uses HWP.
