kvm: x86: Skip TLB flush on fast CR3 switch when indicated by guest When PCIDs are enabled, the MSb of the source operand for a MOV-to-CR3 instruction indicates that the TLB doesn't need to be flushed. This change enables this optimization for MOV-to-CR3s in the guest that have been intercepted by KVM for shadow paging and are handled within the fast CR3 switch path.
