_____________________________________________________________________________________________________________
Add Zhaoxin x86 processor support
We add the code to support Zhaoxin processor because CPU Vendor ID
"Shanghai" and "CentaurHauls" belongs to Zhaoxin now and this part
of the code is maintained and upgraded by Zhaoxin now.
Background:
Shanghai Zhaoxin Semiconductor Co., Ltd ("Zhaoxin") , established in 2013,
headquartered in Zhangjiang, Shanghai, China. Zhaoxin aims at providing
general-purpose x86 processors.
