As a new x86 CPU Vendor, Shanghai Zhaoxin Semiconductor Co., Ltd.
("Zhaoxin") provide high performance general-purpose x86 processors.
CPU Vendor ID "Shanghai" belongs to Zhaoxin.
To enable the supports of Linux kernel to Zhaoxin's CPUs, add a new vendor
type (X86_VENDOR_ZHAOXIN, with value of 10) in
arch/x86/include/asm/processor.h.
To enable the support of Linux kernel's specific configuration to
Zhaoxin's CPUs, add a new file arch/x86/kernel/cpu/zhaoxin.c.
This patch series have been applied and tested successfully on Zhaoxin's
Soc silicon. Also tested on other processors, it works fine and makes no
harm to the existing codes.
v1->v2:
- Rebased on 5.2.0-rc2 and tested against it.
- remove GPL "boilerplate" text in the patch.
- adjust signed-off-by: line match From: line.

v1:
- Rebased on 5.2.0-rc1 and tested against it.
- Split the patch set to small series of patches.
- Rework patch descriptions.
