This patch came from "Srivatsa S. Bhat" <srivatsa.bhat@linux.vnet.ibm.com>,
I think I need to defer.
I spent all day trying to get an alpha cross compiler to build an
unmodified kernel and modules, only to find I didn't need to go that
far and could reproduce the failure with just building vmlinux.
Sorry for my slow response,
Robin
