3com 3c515: make it compile on 64-bit architectures
This driver isn't enabled most places because of the ISA config dependency, but alpha still has it. And I think the 'Jensen' actually did have an ISA slot. However, it doesn't build cleanly, because the "Vortex bus master" code just casts the skb->data pointer to 'int': outl((int) (skb->data), ioaddr + Wn7_MasterAddr); which is all kinds of broken. Even on a good old traditional PC/AT it would be broken because the high bits will be random kernel address bits, but presumably the hardware ignores those bits. I mean, it's ISA. We're talking 16MB dma limits. The "good old days". Make the build happy with this kind of craziness by using the proper isa_virt_to_bus() handling that the full bus master code uses anyway (the Vortex bus mastering is a limited special case). Who knows, this might even work. Reported-by:Guenter Roeck <linux@roeck-us.net> Signed-off-by:
