KVM: nVMX: check host CR3 on vmentry and vmexit
This commit adds missing host CR3 checks. Before entering guest mode, the value of CR3 is checked for reserved bits. After returning, nested_vmx_load_cr3 is called to set the new CR3 value and check and load PDPTRs. Signed-off-by: Ladi Prosek <lprosek@redhat.com> Signed-off-by: Radim Krčmář <rkrcmar@redhat.com>
