[Xenomai-core] [PATCH] x86-userspace: Turn on SMP by default

[Jan Kiszka]

A signigicant portion of x86 systems is SMP these days. Turn on the
corresponding user space option to reflect the situation, specifically
as running SMP-enabled libraries on a single-core system is just
slightly suboptimal while the other way around does not work, forcing
the user to rebuild the Xenomai libs.
