Also I have tested Wei's patches with fixes. It is pretty stable against my 
setup because the direct map has not been actually removed. I am able to run 
XTF tests, boot dom0, launch, restart and destroy guests without breakage. From 
a stability point of view, it probably makes more sense for Wei's patches to go 
in first. From the reviews, it looks like my patches to actually remove the 
direct map can benefit from more RFCs, and can be separated from Wei's into a 
second batch.
