Although we probe for the IPA limits imposed by KVM (and the hardware) when computing the memory map, we still use the old style '0' when creating a scratch VM in kvm_arm_create_scratch_host_vcpu(). On systems that are severely IPA challenged (such as the Apple M1), this results in a failure as KVM cannot use the default 40bit that '0' represents. Instead, probe for the extension and use the reported IPA limit if available.
