[Xenomai] How does the adeos and xenomai project stay synchronized with the linux kernel project?

(apologies for the previous incomplete email)

I've used and followed Xenomai off and on since it forked from RTAI. I'm 
building a new xenomai x86 system after a few years of doing other 
things. I'm noticing that the adeos patches are few and relatively old 
compared to the kernel for the x86 architecture. Kernel version 3.2 has 
moved from .21 to .35 for instance. Meanwhile my (non-rt) systems all 
use 3.4 or 3.6.

So my question is (with the deepest respect for the effort it must take) 
why? Why do the adeos patches lag so much?

Also why were the linux-3.2.21 x86 patch typos which prevent compilation 
not fixed? When such basic thing is not taken care of it makes me doubt 
the integrity of the whole project.

In my community (robotics) xenomai is the go-to RT system for me and 
most of my peers. However the xenomai roadmap and task-market are 
bitrotted and there don't seem to be project status updates on the wiki 
or mailing list which makes it hard to contribute or make plans.

I guess I just want to call attention to the fact that things are 
looking a little rough at xenomai.org and ask whether passers by like 
myself should try to help a little or move on?

kind regards,
