I don't know much about x86 configuration options. It looks like CONFIG_X86_GENERICARCH is fairly new, so I don't know where to look for samples of how it will be set by RH and SuSE.
But if the tlb_uv.o code should be present in "every" distro x86 kernel I don't see the point of having to configure it in. Why not just configure it out for small (embedded) kernels?
