Thank you Uros for the patch. Could you backport this to the 4.8.0?

Hello!
Attached patch adds missing PTA_PRFCHW and PTA_FXSR flags to x86
processor alias table. PRFCHW CPUID flag is shared with 3dnow prefetch
flag, so some additional logic is needed to avoid generating SSE
prefetches for non-SSE 3dNow! targets, while still generating full set
of 3dnow prefetches
