Binbin Wu 241a811f42 hv: ept: apply MCE on page size change mitigation conditionally ... Only apply the software workaround on the models that might be affected by MCE on page size change. For these models that are known immune to the issue, the mitigation is turned off. Atom processors are not afftected by the issue. Also check the CPUID & MSR to check whether the model is immune to the issue: CPU is not vulnerable when both CPUID.(EAX=07H,ECX=0H).EDX[29] and IA32_ARCH_CAPABILITIES[IF_PSCHANGE_MC_NO] are 1. Other cases not listed above, CPU may be vulnerable. Tracked-On: #4121 Signed-off-by: Binbin Wu <binbin.wu@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>		2019-11-18 13:40:24 +08:00
