[PATCH v2 08/46] KVM: SVM: Drop explicit MMU reset at RESET/INIT

From: Sean Christopherson
Date: Tue Jul 13 2021 - 12:33:58 EST


Drop an explicit MMU reset in SVM's vCPU RESET/INIT flow now that the
common x86 path correctly handles conditional MMU resets, e.g. if INIT
arrives while the vCPU is in 64-bit mode.

This reverts commit ebae871a509d ("kvm: svm: reset mmu on VCPU reset").
