#     powerpc/pseries/iommu: Rename "direct window" to "dma window"
#     
#     
#     A previous change introduced the usage of DDW as a bigger indirect DMA
#     mapping when the DDW available size does not map the whole partition.
#     
#     As most of the code that manipulates direct mappings was reused for
#     indirect mappings, it's necessary to rename all names and debug/info
#     messages to reflect that it can be used for both kinds of mapping.
#     
#     Also, defines DEFAULT_DMA_WIN as "ibm,dma-window" to document that
#     it's the name of the default DMA window.
#     
#     Those changes are not supposed to change how the code works in any
#     way, just adjust naming.
