please use the gennalloc directly as discuss with Andrew and Russell my patch
will present in the .40
With Jean-Christophe's patch getting merged, would you be dropping
your PV pool patch?
I'll make that decision once JC's patch has actually been merged.  JC's
patch doesn't do any of the consolidation work, so that needs addressing
still.
Agreed this patch just add the support to have physicall address link to the
pool, the consolidation need to be done on the top of it

Hope see the merge soon
