I'm not yet completely understanding what you mean.

So far the affinity was indirectly assigned to some xnthread by the CPU
the caller of xnshadow_map happened to run on. Now this is done
explicitly, thus in a more robust way (there was an undefined path in
the old code) and without duplicating code (/wrt skins).
