Note that the non-SMP flavours have been identical to the SMP builds
since 2.6.13-1; this was to avoid having to drop then re-add these
flavours if upstream resolved the issue - but that never happened.
Note that this is a measurable performance penalty on non-SMP systems.

This bug breaks module loading on non-SMP ia64 kernels. The workaround
is to temporarily use an SMP config for the non-SMP kernels. (Note that
John Wright is running benchmarks to determine the overhead of running
an SMP kernel on UP systems to help decide if this should be a
permanent change).
