[PATCH v2 0/3] Add support for Zhaoxin Processors

[Tony W Wang-oc]

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-rc5 and tested against it.
 - remove GPL "boilerplate" text in the patch.
 - adjust signed-off-by: line match From: line.
 - run patch series through checkpatch.pl.

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