Comparing the xenomai-2.6.2 x86/patches directory and
http://www.kernel.org/pub/linux/kernel/projects/rt, it appears there's a
common kernel version in 3.2.21.

I'm preparing RPM packages for 3.5 because I assume that's where most
development and bug fixing is going on, and because I hope the work will
be useful beyond the LinuxCNC community.  Unfortunately, RT_PREEMPT
seems to skip linux 3.5 entirely, jumping from 3.4 to 3.6.
