[PATCH?] 2.6.3 - unresolved isa_* symbols on alpha

[Jakub Bogusz]

On alpha CONFIG_ISA is set (to y), but isa_virt_to_bus, isa_page_to_bus,
isa_bus_to_virt are not defined, which results in the following
unresolved symbols:

*** Warning: "isa_virt_to_bus" [drivers/scsi/wd7000.ko] undefined!
*** Warning: "isa_page_to_bus" [drivers/scsi/wd7000.ko] undefined!
*** Warning: "isa_bus_to_virt" [drivers/scsi/wd7000.ko] undefined!
*** Warning: "isa_virt_to_bus" [drivers/char/tpqic02.ko] undefined!
*** Warning: "isa_virt_to_bus" [drivers/char/synclink.ko] undefined!
*** Warning: "isa_bus_to_virt" [drivers/net/ni65.ko] undefined!
*** Warning: "isa_virt_to_bus" [drivers/net/ni65.ko] undefined!
*** Warning: "isa_bus_to_virt" [drivers/net/ni52.ko] undefined!
*** Warning: "isa_virt_to_bus" [net/irda/irda.ko] undefined!
*** Warning: "isa_virt_to_bus" [drivers/net/cs89x0.ko] undefined!
*** Warning: "isa_bus_to_virt" [drivers/net/3c515.ko] undefined!
*** Warning: "isa_virt_to_bus" [drivers/net/3c515.ko] undefined!
*** Warning: "isa_virt_to_bus" [drivers/net/3c505.ko] undefined!

Because virt_to_bus, page_to_bus, bus_to_virt are defined in
asm-alpha/io.h, I copied three defines from asm-i386/io.h - I'm not sure
if it's correct (and should it be in __KERNEL__ or outside __KERNEL__
part), but at least it avoids these unresolved symbols.
