This is a little bug here, machine check is an EXC_STD exception. It does not show up as generated code problem because EXCEPTION_PROLOG_1 does not actually do anything with this parameter if KVM is false, which it is here. Still, it's wrong. I may just resend the series, because it caused a few conflicts in subsequent patches, and I have a few more to add to the end. Thanks, Nick
