#     powerpc/pseries/dma: Enable SWIOTLB
#     
#     So far the pseries platforms has always been using IOMMU making
#     SWIOTLB unnecessary. Now we want secure guests which means devices can
#     only access certain areas of guest physical memory; we are going to
#     use SWIOTLB for this purpose.
#     
#     This allows SWIOTLB for pseries. By default there is no change in
#     behavior.
#     
#     This enables SWIOTLB when the "swiotlb" kernel parameter is set to
#     "force".
#     
#     With the SWIOTLB enabled, the kernel creates a directly mapped DMA
#     window (using the usual DDW mechanism) and implements SWIOTLB on top
#     of that.
