[PlanetCCRMA] Performance degradation with kernel-rt-3.14.17-200.rt9.1.fc20.ccrma.x86_64

[Oleg Samarin]

Hello!

I use Fedora 20 with PlanetCCRMA realtime kernel.

After upgrading the kernel from kernel-rt-3.12.12-300.rt19.1.fc20.ccrma to 
the last one - kernel-rt-3.14.17-200.rt9.1.fc20.ccrma, the huge sound
distortion started occurring. When I boot my station with kernel-rt-3.12.12,
everything seems all right.

The most probably reason is a bug in intel_pstate driver, that prevents CPU
 speeding up: https://bugzilla.kernel.org/show_bug.cgi?id=70941,  There is a
patch that should solve this problem. 

Could you include this patch in the next build of kernel-rt?
