That really doesn't change the fact that it is a completely different
beast, and putting it under entry/ is actively misleading.  Having vdso/
as a separate top level is a good thing, I believe.

I really dislike deep hierarchies, as I said, because my experience has
been that they are more confusing than they are helpful, especially over
time.  The arch-example of badness is of course arch/x86/kernel, which
is a total catch-all, but
