This removes window_size as it is basically a copy of nb_table shifted by SPAPR_TCE_PAGE_SHIFT. As new dynamic DMA windows are going to support windows as big as the entire RAM and this number will be bigger that 32 capacity, we will have to do something about @window_size anyway and removal seems to be the right way to go. This removes dma_window_start/dma_window_size from sPAPRPHBState as they are no longer used. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
