Besides changing the segment bases, is there anything else to do to run KVM-enabled kernels under TCG? (I know nothing about MIPS and it shows). We should consider adding a knob to run them in TCG mode.
This is not blocking this series, and I'm okay with helping or even doing the work, if somebody tells me what to do. :)
