Yinghai is hard at work fixing long-time crappiness of the x86 memory
setup code on 32-bit and 64-bit x86 alike. Contrary to your suggestion
he has not been "ignoring small systems" in any way - he has done the
exact opposite: Yinghai has fixed a ton of small-system bugs and
usability annoyances along the way.
Your attempt trying to cast this much-needed cleanup, fixing and
robustization effort into a negative light is as pityful as it is wrong.
Ingo
