Subject: [GIT PULL] x86/cpu changes for v4.20

# HEAD: 995d5f64b62f20f05b8e0972f07ec4d6c23333c9 tools/cpupower: Add Hygon Dhyana support
The main changes in this cycle were:
- Add support for the "Dhyana" x86 CPUs by Hygon: these are licensed
based on the AMD Zen architecture, and are built and sold in China,
for domestic datacenter use. The code is pretty close to AMD support,
mostly with a few quirks and enumeration differences. (Pu Wen)
- Enable CPUID support on Cyrix 6x86/6x86L processors.
