It is documented in the kernel source in >=20 Sorry to chime in again, but wouldn't this allow to build on platforms which have neither ISA_DMA_API nor ISA, like oldish sparc systems with proprietary S-BUS? Why not ISA_DMA_API || EISA || PCI ? Cheers, Hannes --=20 Dr. Hannes Reinecke zSeries & Storage hare@suse.de +49 911 74053 688 SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 N=FCrnberg GF: J.
