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.
