intel pstate support for vaio pro

[Yu Watanabe]

Dear all,

I use kernel-3.11.0-0.rc2.git0.2.fc20.x86_64 on Sony Vaio Pro.
This machine has Haswell processor, however, the intel_pstate cpufreq driver
does not loaded.

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver
acpi-cpufreq

I googled this issue and found a patch at
https://spicious.com/sony-vaio-pro-11-with-ubuntu.html

Could you apply this patch to the rawhide and f19 kernel?
