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?
