Weird. psmouse-base.c builds ok for me. Perhaps there is a compiler version difference? I'm running a rather old 3.4.6 that came with my RHEL 4.5 release.

Yup ... my script is a little different. It uses $ sed -e '/CONFIG_SMP/d' arch/ia64/configs/tiger_defconfig > .config $ make oldconfig But the net effect should be equivalent.

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 range to a different physical address ... it just makes all the per-cpu stuff link as ordinary variables in .data. The error messages indicate that some of the new code is unaware of this. -Tony
