[PATCH v3] x86/intel: insert Ice Lake-X (server) and Ice Lake-D model numbers

2020-12-23 Thread Igor Druzhinin
LBR, C-state MSRs should correspond to Ice Lake desktop according to External Design Specification vol.2 for both models. Ice Lake-X is known to expose IF_PSCHANGE_MC_NO in IA32_ARCH_CAPABILITIES MSR (confirmed on Whitley SDP) which means the erratum is fixed in hardware for that model and
