Subject[PATCH] isa_virt_to_bus and co on Alpha
From
Date
Richard, Linus, lklm,

The following trivial patchlet (against 2.5.59) adds the missing
isa_virt_to_bus/isa_bus_to_virt API to the Alpha architecture.

This is at least needed by the aha1740 driver. With this patch, the
ol' good Jensen is back running 2.5 ;-).
