Thomas wasn't so much doing a personal attack, it was pointing 
out stupidity and then it was mocking the repeated stupidity. He 
very politely explained his point of view (with which I agree), 
and then you guys pressed the issue and there's just so many 
hours in the merge window, so you asked to be flamed ...

Avi, if you cannot be brought to properly reject incomplete 
patches going in the wrong direction then others maintainers 
interested in the code will do it.

If you start to consistently require from KVM contributors 
"incremental updates" in the right direction, not piling crap on 
crap, then such incidents won't happen. This isn't the first 
such incident but there's hope that it might be the last one.

The rule in arch/x86/ (and many other subsystems) is very 
simple: we don't speed up crappy code. If you want to speed it 
up then make it clean first, *then* is it suited for speedups. 
Crappy code is fragile and bound to introduce bugs, and crappy 
code leads to continued increased maintenance overhead, so 
crappy code is basically under a perpetual code freeze until 
it's uncrapped.

Thanks,

	Ingo
