Subject: [PATCH v3 0/4] x86/mce: Add supports for Zhaoxin MCA

Zhaoxin newer CPUs support MCE, CMCI and LMCE that compatible with
Intel's "Machine-Check Architecture".

To enable the supports of Linux kernel to Zhaoxin's MCA, add
specific patches for Zhaoxin's MCE, CMCI and LMCE. patches about
Zhaoxin's CMCI, LMCE use 3 functions in mce/intel.c, so make these
functions non-static.

Some Zhaoxin's CPUs have MCA bank 8, that only has one error called SVAD
(System View Address Decoder) which be controlled by IA32_MC8.CTL.0.
If enabled, the prefetch on these CPUs will cause SVAD machine check
exception when virtual machine startup and cause system panic. Add a
quirk for these Zhaoxin CPUs MCA bank 8.

v2->v3:
 - Make ifelse-case to switch-case (patch 1/4)
 - Simplify Zhaoxin CPU FMS checking (patch 1/4, 3/4)
 - Revert 1 unused function intel_ppin_init() (patch 2/4)
 - Rework mce_zhaoxin_feature_init() as static (patch 3/4)
 - Rework comment about Zhaoxin MCA SVAD and CMCI (patch 3/4)
 - Rework mce_zhaoxin_feature_clear() as static (patch 4/4)
 - Add comment and change coding style (patch 4/4)

v1->v2:
 - Fix redefinition of "mce_zhaoxin_feature_init" (patch 3/4)
 - Fix redefinition of "mce_zhaoxin_feature_clear" (patch 4/4)

TonyWWang-oc(4):
 x86/mce: Add Zhaoxin MCE support
 x86/mce: Make 3 functions non-static
 x86/mce: Add Zhaoxin CMCI support
 x86/mce: Add Zhaoxin LMCE support
