thanks! Sorry about that: we cross-built on ARM but not on SMP non-x86
platforms so this dependency/breakage went unnoticed.

Yes ... all ia64 builds (UP and SMP) are broken at the moment. Please

I'm having trouble replicating this error. With the latest linux-2.6.git

Some place in there. The CONFIG_SMP=n path in ia64 makes quite
radical changes ... rather than putting all the per-cpu stuff into the
top 64K of address space and providing a per-cpu TLB mapping for that

ah, that was the vital clue. The patch below makes the small memory
model only defined on SMP, and makes the config build/link fine here.
Does this build and boot on your box?

thanks a ton - this produced a link error here too.
after half an hour of head scratching, the updated patch below solves
the build problem.
The problem i believe is this code in
this i believe builds an implicit dependency between the mca_asm.o
position within the image and the ia64_mca_data percpu variable it
accesses - it relies on the immediate 22 addressing mode that has 4MB of
scope. Per chance, the .config you sent creates a 14MB image, and the
