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"
