load_pdptrs can be handed an invalid cr3, and it should not oops. This can happen because we injected #gp in set_cr3() after we set vcpu->cr3 to the invalid value, or from kvm_vcpu_ioctl_set_sregs(), or memory configuration changes after the guest did set_cr3(). We should also copy the pdpte array once, before checking and assigning, otherwise an SMP guest can potentially alter the values between the check and the set. Finally one nitpick: ret = 1 should be done as late as possible: this allows GCC to check for unset "ret" should the function change in future.
