This option enables SMP support in Xenomai userspace.
If this option is turned on while no SMP support is enabled
in the kernel, things will still work. However, if SMP is
enabled in the kernel but this option is not turned on,
Xenomai applications will complain with:
feature mismatch: missing="smp/nosmp"
