[code changes removed]
OK, the changes you sent worked, it compiles now. I still have to go
back and rebuild my source tree with all the other patches that I use
before I can build something I can boot with, but a base elf source
tree does compile now. Here are two patches, the first is a patch to
the BusLogic.patch file and the second is a patch to the irq.h for a
tree patched with the original patch.
