Then submit a patch that changes it to the version you prefer. I already
said that I am fine with the removal of nofullflush. But completly
reverting is the wrong way. For AMD IOMMU I want to use the
iommu=fullflush way because I want to reuse a parameter thats already
there. Thats why I am against your reverting patch.
So now I stop repeating my points again and again. EOD.
