The ARCH=powerpc is the "interesting" part here.

There are many moving targets in the ARCH=powerpc hemisphere for 4xx

Yes, we do. But stable support is only available  with  the  arch/ppc
tree yet.

That's just lucky coincidence...

I'm afraid "normal" here still means arch/ppc  -  hopefully  for  not
long any more. Note: a matching Xenomai patch for arch/ppc will be in
Xenomai 2.4 when it comes out in a few days.
