PNP now initializes device dma masks, which prevents oopses when generic dma calls are made using pnp device nodes. This assumes PNP only uses ISA DMA, with 24 bit addresses; and that it's safe to init those masks for all devices (rather than finding out which devices have been assigned DMA channels, and handling only those).
