Is there any specific dependency of whether this should be built only
with certain archs ? As the case may be, i found the functions
prototypes defined inside the arch specific headers, which definitely
will not compile on PPC64:

# find . -type f | xargs grep -in isa_virt_to_bus
./arch/alpha/include/asm/io.h:119:#define isa_virt_to_bus virt_to_bus
./arch/arm/include/asm/io.h:33:#define isa_virt_to_bus virt_to_phys
./arch/mips/include/asm/io.h:142:static inline unsigned long
isa_virt_to_bus(volatile void * address)
./arch/parisc/include/asm/io.h:17:static inline unsigned long
isa_virt_to_bus(void *addr) {
./arch/x86/include/asm/floppy.h:182:
isa_virt_to_bus(addr) >= 0x1000000 ||
./arch/x86/include/asm/floppy.h:218:    set_dma_addr(FLOPPY_DMA,
isa_virt_to_bus(addr));
./arch/x86/include/asm/io.h:130:static inline unsigned int
isa_virt_to_bus(volatile void *address)

Then there should be some solution to the problem inside
drivers/net/Kconfig
