From: "Maciej S. Szmigiero" <maciej.szmigiero@xxxxxxxxxx> kvm_invalidate_memslot() calls kvm_arch_flush_shadow_memslot() on the active, but KVM_MEMSLOT_INVALID slot. Do it on the inactive (but valid) old slot instead since arch code really should not get passed such invalid slot. Suggested-by: Sean Christopherson <seanjc@xxxxxxxxxx> Signed-off-by: Maciej S.
