From: Tao Su <tao1...@linux.intel.com> Update SierraForest CPU model to add LAM, 4 bits indicating certain bits of IA32_SPEC_CTR are supported(intel-psfd, ipred-ctrl, rrsba-ctrl, bhi-ctrl) and the missing features(ss, tsc-adjust, cldemote, movdiri, movdir64b)
Also add GDS-NO and RFDS-NO to indicate the related vulnerabilities are mitigated in stepping 3.
