Binbin Wu 3d412266bc hv: ept: build 4KB page mapping in EPT for RTVM for MCE on PSC
Deterministic is important for RTVM. The mitigation for MCE on
Page Size Change converts a large page to 4KB pages runtimely during
the vmexit triggered by the instruction fetch in the large page.
These vmexits increase nondeterminacy, which should be avoided for RTVM.
This patch builds 4KB page mapping in EPT for RTVM to avoid these vmexits.
