That ones you quoted are very much irrelevant now. And the behaviour
of the swiotlb disabling will have to change (this patchset is a bit
of a preparation for now) as we now use per-device dma_ops and the
dma-iommu can dip into the swiotlb pool for untrusted devices. In
practive we'll basically have to always initialize the swiotlb buffer
now.
