Just looking in arcnet driver shows that phys_to_virt is used like:
union ArcPacket *arcpacket = (union ArcPacket *) phys_to_virt(dev->mem_start
+ recbuf * 512);
saddr = arcpacket->hardheader.source;
dev->mem_start is usually around 0xd0000. ioremap/iounmap are probably used
rather for PCI memory (high addresses).
