Merge branch 'x86-cpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 cpu updates from Ingo Molnar:
"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"
