   It's not a good idea to have the patch to the defferent subsystems lumped
all together in a single series...

   I was expecting some real changes on how the gen2/3 diff. features in this patch,
but I only saw new info having no real changes where they were needed and having the
changes that did not need to be converted yet...
   Anwyay, I have stopped here for today.
