The current calculation based on the required_dma mask can be significantly off, so that the linear window only overlaps a small part of the DRAM address space. This can lead to the command buffer being unmappable, which is obviously bad. Rework the linear window offset calculation to be based on the command buffer physical address, making sure that the command buffer is always mappable.
